Application :
Cleaning agents, used to clean metal and solder.
Foam blowing agents, used to manufacture rigid or soft PU foam
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 CFC11, 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.
Package : in bulk or in 235kg drums
