Cyclopentane
1.  Molecular formula: C5H*0
2. Cyclopentane can be used as a new foaming agent for rigid polyurethane foam and can be substituted for CFCS which distroies the atmospheric ozone layer. Now it is widely used in producing non-CFCs refrigerator, freezer and cold storage and tubing insulating materials. With the coming of the deadline to use ODS by Montreal protocol; CFCs and HCFCs will prohibited soon, and cyclopentane will be play a key role in the polyurethane foam applications.
