Heat-Resistant Silicone Sheet
−60°C to 200°C
Main applications
heat-resistant silicone sheet for a perfect seal
Key Features
Wide service range: −60°C to 200°C
Characteristic of silicone rubber — elastic from deep cold to high heat, with sealing that stays stable through temperature swings
Excellent elasticity and recovery
Fully recovers after compression — no permanent set under repeated compression, maintaining long-term sealing
Dielectric performance
Silicone's inherent insulating character — also usable as high-temperature insulating pads and gaskets
Chemical, ozone and UV resistance
The weathering resistance characteristic of silicone — no property loss outdoors or in chemical environments
Freely cut and fabricated
In sheet form it is cut immediately to any size or shape — gaskets, pads and seals made on the spot

Notes
- ※FDA-approved food-grade silicone is available separately — confirm the grade when specifying for food or pharmaceutical plant.
- ※Choosing hardness (Shore A): lower hardness seals better, higher hardness resists abrasion and pressure better.
