As a new blowing agent for rigid polyurethane foam, Cyclopentane CAS 287-92-3 is used to replace chlorofluorocarbons (CFCS), which have a damaging effect on the atmospheric ozone layer. Cyclopentane CAS 287-92-3 has been widely used in the production of fluorine-free refrigerators, freezers, cold storage, pipeline insulation and other fields. . As Montreal and other conventions ban ODS deadlines approaching, CFCs and HCFCs products will soon be banned, and cyclopentane will surely become the protagonist in the field of polyurethane foaming agents.

Safety & Storage & Handling

*Keep away from open flames, hot surfaces, and sources of ignition.

*Keep containers tightly closed in a dry, cool, and well-ventilated place. Flammables area. Keep away from heat, sparks, and flame.

*Wear personal protective equipment/face protection. Avoid contact with skin, eyes, or clothing. Avoid ingestion and inhalation.  Use only non-sparking tools. Use spark-proof tools and explosion-proof equipment. To avoid ignition of vapors by static electricity discharge, all metal parts of the equipment must be grounded. Take precautionary measures against static discharges.
