Silicone Sponge Rubber Sheets & Rolls
Silicone sponge sheet, also called silicone sponge rubber, is a closed cell elastomeric material. The sheets stay flexible across extreme temperatures, resist compression set, and keep their resiliency under extended compression. In Stigall Industrial Products' silicone sponge, the cells are completely enclosed and do not interconnect, so the sponge is impervious to the transmission of water or moisture.
Stigall Industrial Products supplies silicone sponge rubber sheets and rolls for sealing, cushioning, vibration control, and insulation. Request a free quote today, or talk to a specialist about your application.
Benefits of Silicone Sponge Rubber Sheets & Rolls
- UL approved silicone sponge materials
- High compressibility and low compression set for sealing applications
- UV and ozone resistant, which supports long-term outdoor performance
- Wide temperature range: Closed cell silicone sponge is flexible from -103° to 401°F (-75 to +205 °C)
- Flame retardant: Used for fire and smoke-blocking applications
- Excellent resistance to weathering: Closed cellular structure means this product provides good water sealing.
- Good thermal insulator
- Meets AMS-3195 (medium density), AMS-3196 (firm density), FAR 25.853, and 21 CFR 177.2600
Silicone Sponge Rubber Sheet Uses
Silicone sponge rubber sheets and rolls are perfect for applications requiring a soft, compressible material. This product is commonly used in press relief pads and other environmental cushioning and gasketing applications. It’s closed cell structure makes it ideal for gasketing, cushioning, insulating and protective applications.
- Gaskets
- Flame retardant cushions
- Solvent resistant gaskets
- Weather and water seals
- Sound and vibration insulation
- Hot and cold thermal insulation
- Cushioning
- Food processing machinery seal
- Pharmaceutical equipment
- Oven seals
How to Choose Silicone Sponge Sheet
Match these attributes to your application before you request a quote:
- Density: soft, medium, firm, or extra firm.
- Form: sheets or continuous rolls, extruded or stripped to size.
- Backing: pressure-sensitive adhesive on one side, stripped to your dimensions.
- Temperature: flexible from -103°F to 401°F (-75°C to +205°C).

- Application: gasketing, cushioning, vibration control, insulation, or sealing.
Silicone Sponge vs. Silicone Foam and Solid Silicone
Silicone sponge is a closed cell, cellular material sold by density: soft, medium, firm, and extra firm. Solid silicone sheet has no air pockets and is specified by durometer, from 30 to 90 Shore A. If your application needs a dense, uniform sheet, see our solid silicone rubber sheet.

Frequently Asked Questions
Closed cell silicone sponge is an elastomeric material with a cellular structure in which the cells are completely enclosed and do not interconnect. It stays flexible across extreme temperatures and resists compression set.
Yes. Because the cells do not interconnect, closed cell silicone sponge is impervious to the transmission of water or moisture, which makes it a good water seal.
Closed cell silicone sponge is flexible from -103°F to 401°F (-75°C to +205°C).
Silicone sponge rubber sheets and rolls are available in soft, medium, firm, and extra firm. Medium density meets AMS-3195 and firm density meets AMS-3196.
Stigall offers flame retardant silicone sponge for fire and smoke-blocking applications, as well as UL approved silicone sponge materials. Request a quote and tell us which approval you need.
Yes. Silicone sponge comes in sheets or continuous rolls, can be extruded or stripped to size, and can be supplied with pressure-sensitive adhesive on one side.
