Copolymerized Gum For HTV
Description
Composition: Copolymer of methyl-(3,3,3-trifluoropropyl)siloxane, small amount of vinyl monomer and other organic silicone. TPD-FS-EH2100 is a high temperature vulcanized elastomer with high molecular weight. It has combined the advantages of both silicone rubber and fluororubber, 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(-70~200℃)
- Good resistance to solvent, oil and other chemical mediums
- 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 to improve the properties of blending materials of silicone rubber and fluorocarbon rubber, and the properties of blending materials of silicone rubber and fluorosilicone rubber. 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.
