CP80, developed by Junyuan Petroleum Group through research and development. This substance can replace and reduce the use of CFCs (Chlorofluorocarbons) and HCFC (Hydrochlorofluorocarbon), which are both GHG emissions, in the production of heat absorbing foam. This substance can contribute to reducing risks of global warming.

Applications of Cyclopentane 80:

Used as solvent for solution polymerization of polyisoprene rubber and cellulose ether, replacing freon as foaming agent for thermal insulation materials of refrigerators and freezers and other hard PU foam, and as reference material for chromatographic analysis.

• Blowing agent for Polyurethane foams (PU foams)
• Insulation boards for building insulation
• Refrigerators, freezers

Normal Pentane is used in consumer merchandise such as spot lifters, cleaners and foaming shave gels and in commercial products such as a blowing agent for expanded polystyrene (foam) insulation. It may also be used as a solvent (extra pure grade) in laboratory, chemical analysis, and other settings where a highly volatile non-polar solvent is needed.

Product Applications

In addition to the above mentioned, Normal Pentane (Pentane) is used principally as a blowing agent in foam production, as a propellant in aerosols and as reaction media for polymerisation processes. It is also used in the laboratory as solvents that can be conveniently and rapidly evaporated.

Highest quality 99+% n-Pentane. Pentanes are relatively inexpensive and are the most volatile liquid alkanes at room temperature, so they are often used in the laboratory as solvents that can be conveniently and rapidly evaporated.

However, because of their nonpolarity and lack of functionality, they dissolve only nonpolar and alkyl-rich compounds. Pentanes are miscible with most common nonpolar solvents such as chlorocarbons, aromatics, and ethers. They are often used in liquid chromatography.

Blend Cyclopentane/Isopentane (50-50) : It is a mixture of 50% of Isopentane and 50% of Cyclopentane. The advantage of using Cyclopentane/Isopentane Pentane Blend 50 / 50 is that it can reduce the foaming cost without affecting other physical properties of foam.

Cyclopentane was first used in Europe as a blowing agent for the production of polyurethane foam in1993 (see German blue angel plan for details). By the end of 1995, almost all European household appliance manufacturers had started to use cyclopentane foaming technology.

Blend Cyclopentane/Isopentane (50-50) acts as a blowing agent. It provides high insulation performance at stable processing conditions. It offers good thermal conductivity. Blend Cyclopentane/Isopentane (50-50) is used in the production of polyurethane foams. The foam is applied to insulation in household, commercial appliances, pipes, reefers, cooling containers and in construction area as boards and panels.

PACKAGING

• ISO Tank Container
• Packaging technical characteristics available upon request to the commercial department.
  Feasibility of filling packaging of the customers if they are in conformity with the legislation.
  Contact us for any other specific packaging.
  According to the density of pentane blends, the filling rate volume of the ISO tank container can not be less than 80%, and the maximum can not exceed 95%.

By adding Isopentane with a boiling point of 28 ° C to Cyclopentane (boiling point of 49 ° C), it can be ensured that the foaming agent can function at a lower temperature and at the initial stage of the polyurethane reaction.

At a lower temperature, the mixture of polyol and isocyanate is still relatively liquid and has a smaller viscosity, which is easier to expand than when the polyurethane raw material rises above 50 ℃. This earlier and more evenly distributed foaming reaction greatly improved the flow performance (filling capacity) of the polyurethane system. This improvement in flow performance can be easily demonstrated by experiments in the laboratory.

In the same formula, gradually increase the proportion of Isopentane to observe the change of fluidity. For example, taking Blend Cyclopentane/Isopentane (50-50) as an example, the ratio of height to mass, an index of fluidity, can be improved by 9%. However, if more isopentane is added, it will help to improve the ratio of height to mass, but the impact will gradually decrease.

USES AND APPLICATIONS

The improvement of fluidity can ensure that the box is filled with a lower filling amount or a lower overall density. However, it is important not only to fill the box at a lower density, but also to maintain the shape stability of foam at a lower density.

In addition, the addition of Isopentane to Cyclopentane will increase the internal pressure of the cell. For example, the internal pressure of Cyclopentane foamed foam rises from 45 kPa to 55 kPa for Cyclopentane / Isopentane foamed foam (the mass ratio of Cyclopentane to Isopentane is 7:3).

The higher internal pressure of the cell reduces the influence of the external force on the foam, that is, the pressure difference between the inside and outside of the cell.

When designing and developing the formula of Cyclo/Isopentane foaming system, the strength of foam should be increased, and it has good compatibility with Cyclo/Isopentane. It is required that the combined polyether blended with pentane should be a clear and transparent liquid.

This Blend Cyclopentane/Isopentane (50-50) is the ideal compromise between the mechanical and heat resistances of the resulting foam. Harmless to the ozone layer, it is especially fit as a substitute for the HCFC 141 b.

SECTION 4 First aid measures Description of first aid measures

Indication of any immediate medical attention and special treatment needed
For acute or short term repeated exposures to petroleum distillates or related hydrocarbons:
Primary threat to life, from pure petroleum distillate ingestion and/or inhalation, is respiratory failure.
Patients should be quickly evaluated for signs of respiratory distress (e.g. cyanosis, tachypnoea, intercostal retraction, obtundation) and given oxygen. Patients with inadequate tidal volumes or poor arterial blood gases (pO2 50 mm Hg) should be intubated.
Arrhythmias complicate some hydrocarbon ingestion and/or inhalation and electrocardiographic evidence of myocardial injury has been reported; intravenous lines and cardiac monitors should be established in obviously symptomatic patients. The lungs excrete inhaled solvents, so that hyperventilation improves clearance.
A chest x-ray should be taken immediately after stabilisation of breathing and circulation to document aspiration and detect the presence of pneumothorax. Epinephrine (adrenalin) is not recommended for treatment of bronchospasm because of potential myocardial sensitisation to catecholamines. Inhaled cardioselective bronchodilators (e.g. Alupent, Salbutamol) are the preferred agents, with aminophylline a second choice.
Lavage is indicated in patients who require decontamination; ensure use of cuffed endotracheal tube in adult patients. [Ellenhorn and Barceloux: Medical Toxicology]
Any material aspirated during vomiting may produce lung injury. Therefore emesis should not be induced mechanically or pharmacologically. Mechanical means should be used if it is considered necessary to evacuate the stomach contents; these include gastric lavage after endotracheal intubation. If spontaneous vomiting has occurred after ingestion, the patient should be monitored for difficult breathing, as adverse effects of aspiration into the lungs may be delayed up to 48 hours.

MATERIAL DATA
Exposure controls
Appropriate engineering
controls Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection. The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard “physically” away from the worker and ventilation that strategically “adds” and “removes” air in the work environment.
Personal protection
Eye and face protection Safety glasses with side shields. Chemical goggles.
Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document,
describing the wearing of lenses or restrictions on use, should be created for each workplace or task.
Skin protection See Hand protection below
Hands/feet protection The selection of suitable gloves does not only depend on the material, but also on further marks of quality which vary from manufacturer to manufacturer. Where the chemical is a preparation of several substances, the resistance of the glove material can not be calculated in advance and has therefore to be checked prior to the application.
The exact break through time for substances has to be obtained from the manufacturer of the protective gloves and has to be observed when making a final choice.
Personal hygiene is a key element of effective hand care.
Polyethylene gloves
Wear chemical protective gloves, e.g. PVC.
Wear safety footwear or safety gumboots, e.g. Rubber
Body protection See Other protection below
Other Protection
Overalls. PVC Apron.
PVC protective suit may be required if exposure severe. Eyewash unit.

* CPI – Chemwatch Performance Index A: Best Selection
B: Satisfactory; may degrade after 4 hours continuous immersion C: Poor to Dangerous Choice for other than short term immersion
NOTE: As a series of factors will influence the actual performance of the glove, a final selection must be based on detailed observation. –
* Where the glove is to be used on a short term, casual or infrequent basis, factors such as “feel” or convenience (e.g. disposability), may dictate a choice of gloves which might otherwise be unsuitable following long-term or frequent use. A qualified practitioner should be consulted.

Respiratory protection
Type AX Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent)
Cartridge respirators should never be used for emergency ingress or in areas of unknown vapour concentrations or oxygen content.
The wearer must be warned to leave the contaminated area immediately on detecting any odours through the respirator. The odour may indicate that the mask is not functioning properly, that the vapour concentration is too high, or that the mask is not properly fitted. Because of these limitations, only restricted use of cartridge respirators is considered appropriate.
Cartridge performance is affected by humidity. Cartridges should be changed after 2 hr of continuous use unless it is determined that the humidity is less than 75%, in which case, cartridges can be used for 4 hr. Used cartridges should be discarded daily, regardless of the length of time used

SECTION 11 Toxicological information

Information on toxicological effects

Inhaled
Inhalation of vapours may cause drowsiness and dizziness. This may be accompanied by narcosis, reduced alertness, loss of reflexes, lack of coordination and vertigo.
Limited evidence or practical experience suggests that the material may produce irritation of the respiratory system, in a significant number of individuals, following inhalation. In contrast to most organs, the lung is able to respond to a chemical insult by first removing or neutralising the irritant and then repairing the damage. The repair process, which initially evolved to protect mammalian lungs from foreign matter and antigens, may however, produce further lung damage resulting in the impairment of gas exchange, the primary function of the lungs. Respiratory tract irritation often results in an inflammatory response involving the recruitment and activation of many cell types, mainly derived from the vascular system.
Acute effects from inhalation of high concentrations of vapour are pulmonary irritation, including coughing, with nausea; central nervous system depression – characterised by headache and dizziness, increased reaction time, fatigue and loss of co-ordination
Central nervous system (CNS) depression may include nonspecific discomfort, symptoms of giddiness, headache, dizziness, nausea, anaesthetic effects, slowed reaction time, slurred speech and may progress to unconsciousness. Serious poisonings may result in respiratory depression and may be fatal.
Symptoms of pentane inhalation exposure may include, hyperactivity, anaesthesia and a persistent taste of gasoline. Light anaesthesia occurs in mice after 10 minutes exposure to 70000 ppm n-pentane.
Inhalation of high vapour concentrations may result in coughing, headache, mild depression, incoordination, blurred vision, confusion, loss of appetite, nausea, vomiting, irregular heartbeat and unconsciousness.
Concentrations of 270 to 400 mg/l isopentane may cause narcosis and cardiac sensitisation .

Material is highly volatile and may quickly form a concentrated atmosphere in confined or unventilated areas. The vapour may displace and replace air in breathing zone, acting as a simple asphyxiant. This may happen with little warning of overexposure.
An acute exposure due to inhalation of cyclopentane can result in light headedness. As with all alicyclic hydrocarbons, cyclopentane is a central nervous system depressant. Symptoms of acute exposure, in high concentrations include excitement, loss of equilibrium, stupor, coma, and, occasionally, respiratory failure.
Inhalation of vapours or aerosols (mists, fumes), generated by the material during the course of normal handling, may be damaging to the health of the individual.

Ingestion
Swallowing of the liquid may cause aspiration of vomit into the lungs with the risk of haemorrhaging, pulmonary oedema, progressing to chemical pneumonitis; serious consequences may result.
Signs and symptoms of chemical (aspiration) pneumonitis may include coughing, gasping, choking, burning of the mouth, difficult breathing, and bluish coloured skin (cyanosis).
Accidental ingestion of the material may be damaging to the health of the individual.
Ingestion of pentanes may result in diarrhoea, haemorrhage of the mucous membranes, or when the liquid vapourises in the trachea, asphyxiation leading to brain damage or death. Ingestion may also cause nausea, vomiting and abdominal swelling. Large doses (1 ml/kg) may cause central nervous system depression, ventricular fibrillation and kidney, liver and bone marrow damage.
Considered an unlikely route of entry in commercial/industrial environments. The liquid may produce gastrointestinal discomfort and may be harmful if swallowed. Ingestion may result in nausea, pain and vomiting. Vomit entering the lungs by aspiration may cause potentially lethal
chemical pneumonitis

Skin
Contact Repeated exposure may cause skin cracking, flaking or drying following normal handling and use.
Symptoms of pentane exposure may include drying, cracking, itching, blistering, redness, pigmentation, swelling, burning and pain. Because pentane boils just below body temperature, absorption is not expected to be a significant route of entry. Toluene by comparison is absorbed through the skin at 20 times the rate of n-pentane
Entry into the blood-stream through, for example, cuts, abrasions, puncture wounds or lesions, may produce systemic injury with harmful
effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.

Eye
Limited evidence exists, or practical experience suggests, that the material may cause eye irritation in a substantial number of individuals and/or is expected to produce significant ocular lesions which are present twenty-four hours or more after instillation into the eye(s) of experimental animals. Repeated or prolonged eye contact may cause inflammation characterised by temporary redness (similar to windburn) of the conjunctiva (conjunctivitis); temporary impairment of vision and/or other transient eye damage/ulceration may occur.
Eye-contact with the liquid pentanes may result in inflammation of the iris and mucous membranes resulting in pain and lachrymation. Eye contact with liquid or very high vapour concentrations may result in drying, redness, swelling and pain.

Chronic
Prolonged or repeated skin contact may cause drying with cracking, irritation and possible dermatitis following.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems.
Chronic exposure to pentanes may result in chemical pneumonitis, pulmonary oedema or peripheral neuropathy. Prolonged or repeated inhalation may cause dizziness, weakness, weight loss, anaemia, nervousness, pain in the limbs and peripheral numbness (“pins and needles”)
