The difference between cyclopentane and R141B
Source: | Author:Tom | Published time: 2020-11-21 | 41 Views | Share:
As a new foaming agent for rigid polyurethane foams, cyclopentane is used to replace chlorofluorocarbons (CFCS), which are destructive to the atmospheric ozone layer. Now has been widely used in the production of fluorine-free refrigerators, freezers, cold storage, pipe insulation and other fields. With Montreal and other deadlines for banning ODS approaching, CFCS and HCFCS products will soon be banned, and cyclopentane is set to become the leading player in the polyurethane foaming agent field.

R-141b is also known as dichlorofluoroethane and HCFC141b.  It is a highly purified liquid and can be used as a detergent and foaming agent in place of R11 and R113.  R-141b has a wide range of applications in the field of plastic foam.  R-141b has excellent properties such as low gas phase thermal conductivity.  Compared to R11, R141b has destroyed one-tenth of the atmospheric ozone layer equivalent to R11 and has therefore been identified as an ideal substitute for fully halogenated CFCS.
