Liquid silicone rubber material for composite insulator

Product Description
2-part catalyzed by platinum, high voltage resistant and low viscosity liquid silicone rubber, which is particularly suitable for producing composite insulator, mixing ratio of parts A:B=1:1, The appearance of A is transparent and B is grey.

Key Features
  • Low viscosity, be apt to injection molding
  • Long pot life
  • High dielectric strength
  • Excellent tracking resistance
  • Excellent surface hydrophobic property

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
Composite insulator
