Understanding Silicone Rubber
Silicone rubber is a high-performance synthetic elastomer composed of silicone and other molecules (carbon, hydrogen, and oxygen). It is characterized by high viscosity and elasticity, as well as superior abrasion resistance, chemical stability, insulating properties, temperature resistance, and weatherability compared to organic rubber.
Key Properties
Operating temperature range: -100°C to 350°C (depending on exposure duration)
Weatherability: Resistant to wind, rain, UV radiation, and ozone
Moisture resistance: 1% water absorption in various water temperatures
Steam resistance: Indefinite resistance to unpressurized steam
Chemical resistance: Resistant to oils, solvents, polar organic compounds, and diluted acids/alkalis
Electrical insulation: 1TΩ*m-100TΩ*m across wide temperature and frequency ranges
Types of Silicone Rubber
Silicone rubber varies by viscosity and processing method:
Solid Silicone Rubber (HTV): Long polymer chains processed by conventional methods
