Temperature range
Maintains performance from extreme cold to high heat. Operates reliably across wide temperature ranges.
Durability
Designed for long-term mechanical performance. Resists wear, aging, and environmental stress.
Flexibility
Retains elasticity under varying conditions. Supports dynamic and sealing applications.
Low compression set
Maintains sealing force after repeated compression. Ensures long-term shape recovery.
Flame retardancy
Inherently resistant to ignition and flame spread. Suitable for safety-critical applications.
Electrical insulation
Provides stable dielectric performance. Ideal for electrical and electronic components.
Weather resistance
Resists UV, ozone, and environmental exposure. Performs reliably in outdoor applications.
Hydrophobicity
Naturally repels water and moisture. Supports waterproof and sealing designs.
Transparency
Can be formulated for optical clarity. Easily pigmented for functional or aesthetic designs.
Silicone elastomers are used in sealing, insulation, vibration damping, thermal management, and protective applications across automotive, healthcare, energy, electronics, and industrial markets.
Liquid Silicone Rubber (LSR) is pumpable and typically molded for high-volume precision parts, while High Consistency Rubber (HCR) is more solid and commonly processed via extrusion or compression molding.
Select grades are formulated to meet biocompatibility requirements and are suitable for medical devices, pharmaceutical processing, and regulated food contact applications.
Yes. Silicone elastomers maintain performance across a wide temperature range, making them suitable for both high heat and low temperature environments.
Certain grades meet UL94 V0 flammability standards and are designed for safety critical and fire-resistant applications.
Yes. Silicone elastomers can be formulated for electrical conductivity, antistatic performance, EMI shielding, or enhanced thermal conductivity for heat management applications.
