Description

SENMA's High-Temperature Vulcanized (HTV) Silicone Rubber is an industrial-grade elastomer engineered for extreme thermal and mechanical stress environments. Through precision vulcanization, this solid silicone rubber delivers unmatched durability and heat resistance, making it ideal for critical sealing and insulation applications.

High-Temperature Performance
SENMA’s HTV Silicone Rubber withstands continuous exposure from -50°C to +200°C (peak 250°C), maintaining flexibility and structural integrity under prolonged heat. Its low compression set (≤15% at 200°C) ensures reliable sealing in demanding conditions, outperforming conventional rubbers in thermal aging resistance.

Engineered for Industrial Demands
With high tensile strength (6–10 MPa) and elongation (400–600% ), this material resists cracking and deformation under dynamic loads. Available in customizable hardness (Shore A 30–80), it meets diverse OEM requirements for gaskets, seals, and vibration dampers.

Certified & Safe
Compliant with RoHS, REACH, and FDA standards, our HTV silicone rubber is suitable for food contact, medical devices, and electronics. Flame-retardant options (UL94 V0/HB) are available for high-risk applications.

Global Applications

Trusted by industries including:

  • Automotive: Engine gaskets, turbocharger hoses
  • Energy: Solar panel seals, transformer insulation
  • Industrial: Conveyor belts, high-temperature seals
  • Electronics: Keypad membranes, thermal pads
