R141a

Name of Product

R141a (1,1-dichloro-1-fluoroethane) (HCFC-141b)

Brief Description

Because of its low gas phase thermal conductivity SOLKANE® 141b is the best available replacement to CFC11 as a blowing agent for rigid polyurethane insulating foams. Compared to FC11, SOLKANE® 141b is approximately ten times less harmful to stratospheric ozone and is therefore recognized as a viable solution allowing the rapid phase-out of CFCs.
