Integral skin foams employing pentafluorobutane blowing agents

   
   

It has been found that non-chlorinated pentafluorobutane blowing agents may be used alone or in combination with water in flexible integral skin foams. For example, foams prepared using 1,1,1,3,3-pentafluorobutane (HFC 365mfc) alone or in combination with water or other non-cholorinated hydrocarbons such as heptafluoropropane exhibit improved physical characteristics, such as resistance to abrasion and cracking, on flex comparable to conventional chlorinated fluorocarbon blown foam.

È stato trovato che gli agenti di salto non-clorurati del pentafluorobutane possono essere usati da solo o congiuntamente ad acqua in pelle integrale flessibile spuma. Per esempio, spuma preparato usando 1,1,1,3,3-pentafluorobutane (HFC 365mfc) da solo o congiuntamente ad acqua o altro non-cholorinated gli idrocarburi quali le caratteristiche fisiche migliorate esposizione del heptafluoropropane, quale resistenza ad abrasione ed a spezzarsi, sulla flessione paragonabile a gomma piuma saltata fluorocarburo clorurata convenzionale.
