Low Compression Set Silicone Rubber (precipitated or fumed) is a one-part, solid-state silicone that maintains exceptional elasticity and minimal permanent deformation under prolonged compression or high-temperature conditions. With superior weatherability, chemical resistance, and easy processability, it’s widely used in seals, O-rings, medical components, and food-contact applications, where long-lasting sealing performance and shape recovery are critical.
Features
- High resilience
- Low compression deformation
Application
Rubber roller, Automobile accessories, Sealing
