Ensinger PEI

CHT SilSo Clear 21002 Liquid Silicone
Categories: Polymer; Thermoset; Silicone; Silicone Rubber; Liquid Silicone Rubber (LSR)

Material Notes: Description: This product is a transparent and colorless silicone formulation and is ideal for optical injection molding applications. The viscosity profile enables excellent flow around components and is excellent for potting complex parts. The chemical composition results in a cured product that is hydrolytically stable as well as reversion resistant. The silicone elastomer provides electrical insulation and physical shock resistance of components and enables environmental protection.

Key Features

  • Convenient mixing 1:1 ratio for use in automatic dispensing equipment or hand mixing
  • Contains no solvents
  • Non-yellowing catalyst system
  • Stable transmittance over time
Key Applications
  • Injection molding
  • Optical / magnifying lenses
  • LED modules
  • Solar collection products
Application: SilSo Clear 21002 is designed for optical injection molding applications such as lenses, lightguides and LEDs.
