Description

Low Shrinkage Tin Cure Liquid Silicone Rubber for Injection Molding

HN-620 A/B is a two-component tin cure liquid silicone rubber with low shrinkage of ≤0.2%, engineered for injection molding and crafts making. Cured at room temperature with a 100:2 mixing ratio, it offers high tear strength and easy perfusion for detailed and durable molds.

Key Features

  • Low Shrinkage ≤0.2% - Precise reproduction of the finest and most complex details
  • High Tear Strength - 19.8-24.3 kN/m for long service life and frequent mold turnover
  • High Elongation 600-720% - Excellent flexibility for complex segmented molds
  • Easy Perfusion & Good Fluidity - Self-leveling, easy foaming release for complete mold filling
  • High & Low Temperature Resistance - Acid, alkali and aging resistant for demanding environments
  • Easy Demolding - Finished products will not turn white, reusable many times
  • Customizable - Color, hardness, viscosity and operating time adjustable per requirements
