Silicone Sponge Rubber Strips

Closed-cell silicone sponge strips are highly elastic, soft foam sealing strips with a unique porous structure. Unlike solid rubber strips, they offer an ultra-soft touch, excellent compression resilience, and uniform cushioning performance. Unlike ordinary EPDM or PU sponge, silicone sponge extruded strips do not produce odors or aging powder when heated, ensuring cleanliness and stability over long-term use. With reliable high and low temperature resistance, it is an ideal sealing, shockproof, and heat-insulating material for high-temperature equipment. It is widely used in the customization and supply of home appliances, electronics, and industrial equipment for manufacturers.

Our silicone sponge gasket strips are made from high-quality silicone sponge material through precise extrusion. A wide range of sizes, densities, colors, and professional grades are available, providing customized solutions to meet your specific needs. Our silicone sponge profile maintains stable softness and elasticity even in extreme temperature environments, and can even withstand intermittent use up to 230°C. Its fine uniform internal pore structure allows it to perfectly fit irregular uneven gaps, achieving a tight seal while providing effective cushioning and noise reduction. Sponge extrusion profiles come in a variety of shapes and designs, from tubes, cords, strips, to profiles, and can be supplied with self-adhesive backing (SAB) as needed, ensuring you always get the product best suited to your needs.


Key Features of Silicone Sponge Strips:

1. High & low temperature resistant – Stable performance from -60°C to 200°C, suitable for hot and cold environments.
2. Ultra-soft & high resilience – Fits irregular gaps tightly, no gap leakage after long compression
3. Heat insulation & energy saving – Excellent thermal insulation performance for heating equipment
4. Shock absorption & noise reduction – Buffers vibration and reduces equipment operating noise
5. Aging & ozone resistant – Long service life, no powdering or cracking
6. Excellent dustproof, waterproof, airtight, and thermal insulation effects.
