Silicones

$0.00

Silicone elastomers are a family of high-performance materials based on polydimethylsiloxane (PDMS) chemistry. They are known for their thermal stability, flexibility, biocompatibility, and excellent electrical insulation, making them widely used in medical, automotive, and electrical applications where performance under extreme conditions is critical.

Key Types of Silicone Elastomers

PDMS (Polydimethylsiloxane)

A base silicone polymer with a flexible Si–O backbone that provides:

  • Outstanding thermal resistance (–50°C to 200°C+)

  • Excellent dielectric properties

  • Low toxicity and high biocompatibility
    Used extensively as the foundation for medical-grade silicones, sealants, and insulation materials.

HTV (High-Temperature Vulcanizing Silicone)

A gum-based silicone compound cured at elevated temperatures.

  • High mechanical strength

  • Excellent heat and aging resistance

  • Suitable for compression, transfer, and injection molding
    Common in automotive seals, gaskets, and industrial components.

RTV (Room-Temperature Vulcanizing Silicone)

Cures at ambient temperatures (one-part or two-part systems).

  • Easy to apply and process

  • Strong adhesion to many substrates

  • Ideal for sealing, potting, and encapsulation in electrical and electronics applications

FVMQ (Fluorosilicone Rubber)

A fluorinated silicone elastomer providing:

  • Exceptional fuel, solvent, and chemical resistance

  • Wide service temperature range

  • Superior performance in aggressive automotive and aerospace environments
    Used in fuel system seals, diaphragms, and O-rings.
