BLOWING AGENT FOR A THERMAL INSULATING FOAM AND METHOD FOR FORMING A THERMAL INSULATING FOAM

摘要

A blowing agent for a thermal insulating foam comprising at least one fluoroalkene of Formula I: XCFzR3�z (I) where X is a C2 or a C3 unsaturated, substituted or unsubstituted, alkyl radical, R is independently CI, F, Br, I or H, and z is 1 to 3, said blowing agent having a Global Warming Potential (GWP) of not greater than 1000. The invention is also for a foamable composition and foam premix comprising said agent and method of forming a thermal insulating foam using said agent.
