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.
