Low Compression Set Fluorosilicone Rubber Compound Topda FS-R8400 is translucent uncatalyzed fluorosilicone rubber base mixed evenly with some kinds of fillers and additives. Its compression set is lower than that of normal fluorosilicone rubber compound.
- Low compression set
- Integrated advantages of both silicone rubber and fluororubber
- Easily pigmented
- Wide working temperature range(-60°C-200°C)
- Good resistance to solvent & fuel oil
- High tensile force retention at high temperature which is like silicone rubber
- High insulation
- High selective permeability
- Meet requirements of environment protection

How to use
Properties obtained using 0.6-0.8 phr 2,5-bis (tert-butylperoxy)-2,5-dimethyl hexane (DHBP). Molded 15min at 170℃, post-cured 4hr at 200℃. If other cure temperature needed, vulcanization system shall be changed.
Used as sealing materials to resist petroleum oil, lubricant oil, hydraulic oil, transformer oil, and non-polar chemical reagents in low temperature and/or high temperature environments.
Used to produce molded, extruded, and calendered fluorosilicone parts, such as O-rings, gaskets, sealing rings, oil seals, sealing strips, sensor materials, diaphragms, membranes, and clips for fluorosilicone gaskets and pipes.
It is available in 12.5 Kg per plastic bag and 2 bags in 1 carton.
