Smooth Silicone sponge rubber sheet

Smooth Skin & Closed Cell Structure

Different from regular rough silicone sponge sheets, our smooth silicone sponge rubber sheet comes with a dense, seamless smooth outer layer. The closed-cell internal structure prevents water, dust and gas penetration. When compressed, it quickly rebounds to its original shape, maintaining reliable sealing even under repeated squeezing. The smooth surface does not leave residues on contact surfaces, is easy to cut and bond, and resists sticking to many materials. It avoids leaks caused by uneven porous surfaces, making it ideal for gasket production.

Premium Silicone Material & Performance

Made of food grade or industrial grade silicone compound, this smooth silicone sponge sheet has outstanding heat and cold resistance. It can continuously work within a wide temperature range, remaining flexible and stable without hardening, cracking or melting. The material is weather resistant, UV resistant and ozone resistant, suitable for long-term outdoor use. It is non-toxic, low odor and has great compression set resistance.

Key Advantages

• Smooth sealed surface: No open pores, excellent sealing performance, no residue transfer

• Closed cell foam structure: Lightweight, water and air tight, good cushioning & shock absorption

• Wide temperature tolerance: Stable performance under high heat and low temperature conditions

• Great compression recovery: Bounces back after repeated compression, long service life

• UV & ozone resistant: Handles outdoor and harsh environmental exposure

• Easy fabrication: Simple to cut, punch, die-cut into custom gaskets and pads

• Multiple grades available: Industrial grade and food safe options for different projects

Smooth Silicone Sponge Rubber Sheet | High Temp Silicone Foam Sheet for Sealing & Insulation Meta Description：Smooth silicone sponge rubber sheet with fine smooth surface. Flexible closed cell silicone foam, heat resistant, weatherproof, good compression recovery. Widely used for gaskets, sealing, heat insulation, available in rolls and sheets, custom sizes.

Smooth Silicone Sponge Rubber Sheet, also known as smooth silicone foam sheet, is a lightweight closed-cell silicone sponge material with a fine, smooth outer skin. Unlike ordinary porous silicone sponge, this variant features a uniform smooth surface without rough open pores. It combines soft cushioning performance, excellent high-temperature resistance and stable sealing capability, widely adopted for industrial sealing, thermal insulation, shock absorption and anti-skid applications.

Typical Applications

• Heat resistant gaskets, sealing strips for ovens, machinery and heating equipment

• Shock absorption pads for electronic equipment and automotive components

• Thermal insulation lining for industrial cabinets and lighting fixtures

• Food & beverage machinery sealing (food grade option)

• Door and window sealing for high temperature workshops

• Anti-vibration cushion pads for medical devices
