Description

Composition: Copolymer made by D3f and methyl-vinyl-cyclosiloxane

Fluorosilicone Elastomer Topda FS-EH2000 is the copolymer made by D3f and methyl-vinyl-cyclosiloxane through polymerization. It is a high temperature vulcanized elastomer with high molecular weight. It has combined the advantages of both silicone rubber and fluorine rubber, therefore it can be used as sealing materials in special places with requirements of resistance to high and/or low temperature, oil, solvent and other mediums.  

Features

• Wide application temperature range(-60~200℃)
• Good resistance to solvent, oil and other chemical mediums
• Low volatile content
• Easily mixed with different types of fillers such as silica, calcium carbonate, etc.

Application

Used to produce fluorosilicone rubber parts with various hardness, such as O-rings, gaskets, sealing strips, oil seals, sensor material, diaphragms and clips for spacers. 

Used as sealing materials in poor condition of environment, which requires material to resist to high & low temperatures, fuels, lubricants, hydraulic oil, transformer oil or nonpolar chemical reagents.
