Cyclopentane uses: it is used to replace freon for refrigerators, freezers and other rigid PU foam foaming agents. It is used as solvent for solvent polymerization of polyisoprene rubber and cellulose ether, instead of Freon used in refrigerator, freezer and other hard PU foam foaming agents. Instead of freon, it is used as a thermal insulation material for refrigerators and freezers and other foaming agents for rigid PU foam.
