Fluoropolymer elastomer SCF 26,32.
Offer type: salePublished: 28.01.2017
Ftorkauchuki — elastic high molecular weight polymers. SKF-26 is a copolymer of vinylidene fluoride and HEXAFLUOROPROPYLENE, and SKF-32 – a copolymer of vinylidene fluoride and chlorotrifluorethylene.
For resistance to aggressive environments, including gasoline and various oils, ftorkauchuki far superior to all other non-fluorinated rubbers. When immersed in fuming nitric acid for 7 days at 20°C, there is swelling of the rubber samples, but retained good elasticity. The elasticity is maintained at the boil samples in fuming nitric acid for several days, while regular, does not contain fluorine rubbers, in these conditions, are destroyed in a few minutes.
Ftorkauchuki SKF-32 and SKF-26 have very high thermal resistance. Prolonged heating for hundreds of hours at 200°C does not cause significant degradation of rubbers. While retaining their strength and elasticity. Decomposition temperature perkauskas above 300° C.
Ftorkauchuki SKF-32 and SKF-26 dissolve in esters, ketones, swell in aromatic hydrocarbons and certain other solvents.
