Common Silicone Rubber for Molding&Extrusion
6.5Mpa Common Silicone Rubber Polymer For Automotive Strong Electrical Insulation
DESCRIPTION
Silicones are a versatile family of high-performance materials that can take on various forms - liquids, solids, semi-viscous pastes, oils, greases, and rubber - due to their unique molecular structure. We utilize this versatile rubber material in diverse settings, from highly aesthetic components to food-grade kitchen utensils.
This semi-organic synthetic rubber, made up of a chain of silicon and oxygen atoms, is often mistaken for the chemical element silicon. Unlike most other types of rubber that contain carbon and hydrogen atoms, silicone consists of a unique molecular structure that provides exceptional qualities.

ADVANTAGES
1. Exceptional Heat Resistance
Silicone rubber stands out for its unparalleled heat resistance, with some compounds capable of withstanding temperatures up to 305°C. Its thermal stability ensures that it retains its structure and properties across a wide temperature range, extending to low temperatures of -100°C, where it maintains its flexibility.
2. Hygienic and Safe
Silicone rubber's non-porous nature makes it highly resistant to bacterial build-up, making it a popular choice for kitchen utensils. Its non-toxic and water-repellent properties make it ideal for food and beverage applications where food-grade compounds offer peace of mind. Additionally, silicone rubber is recyclable at specialized plants, contributing to its safety and sustainability.
