Product Description

Description

General Purpose Fluorosilicone Rubber Compound Topda FS-R8200 is light yellow translucent uncatalyzed fluorosilicone rubber base mixed evenly with some kinds of fillers and additives. It can be used as seal material in special condition with requirements of resistance to high and low temperature, oil and some other chemical mediums. 

Features

  • Integrated advantages of both silicone rubber and fluororubber
  • Wide working temperature range(-60°C-200°C)
  • Good resistance to solvent & fuel oil 
  • Easily pigmented 
  • High tensile force retention at high temperature which is like silicone rubber
  • High insulation
  • High selective permeability
