Liquid silicone rubber material of low viscosity and pressure injection molding

Product Description
2-part liquid silicone rubber, which is particularly suitable for injection molding with tracking resistance 1A3.5 grade, mixing ratio of parts A:B=1:1, catalyzed by platinum. The appearance of A is transparent and B is grey.

Key Features
  • Injection molding
  • Rapid vulcanization
  • Excellent tracking resistance
  • Long usable life

At the temperature of 20°C and in the condition of air-proof, the shelf life is 5 days after mixing A and B, the shelf life will decrease with the increasing of the temperature.

Applications
  • Lightning arrester
General Information
