Fluorosilicon elastomer WEI-R-1000

　　Composition: copolymer of methyl-(3,3,3-trifluoropropyl) siloxane and small amount of vinyl monomer

　　Characteristics:Fluorosilicon elastomer WEI-R-1000 is a heat vulcanization elastomer with high molecular weight. It appears as transparent gum. This product unites good performances of fluoroelastomer and siliconelastomer as follows, therefore can be used as seal materials in special positions with requirements to resist high and/or low temperature, oil and other medium.

　　wide application temperature range: -60℃～200℃good resistance to solvent and oil like fluoroelastomerstrong elongation retention at high temperature like siliconelastomergood electric insulationlow leakage, comply to requirements by environment protectionItem
