High-Temp Grade— high temperature and special duty

+250°C · CONTINUOUS
Choose one of three special compositions according to the operating environment.
  • Hi-Temp Silicone+250 °C continuous, +300 °C briefly. For semiconductor thermal stacks and ovens.
  • Thermal-ConductiveCeramic filled, for heat-dissipation pads (0.8–3.0 W/mK).
  • Flame-RetardantUL94 V-0, self-extinguishing. For electrical and battery insulation.
— Applications

Applications

/ SEMICONDUCTOR

Thermal Stack

High-temperature, high-purity silicone pads fitted into hot plates, chucks and bonding stages on wafer processing equipment.

/ MEDICAL · FOOD

Medical / Food Contact

FDA and USP Class VI grades for surfaces in direct contact on medical devices and food processing equipment.

/ ELECTRICAL

HV Insulation

Dielectric strength around 20 kV/mm makes it a high-voltage insulating spacer in switchgear, transformers and EV battery packs.
