cyclopentane is used in the manufacture of synthetic resins and rubber adhesives and also as a blowing agent in the manufacture of polyurethane insulating foam, as found in many domestic appliances such as refrigerators and freezers, replacing environmentally damaging alternatives such as cfc-11 and hcfc-141b. more advanced technologies, such as computer hard drives and outerspace equipment employ multiply alkylated cyclopentane (mac) lubricants because of their extremely low volatility.
