When an application requires 내열성, 유연성, compression recovery and reliable sealing, silicone sponge rubber is an excellent material choice. 우리의 High Temperature Resistant Silicone Sponge Rubber Sheet – Red Silicone Foam Pad Mat is designed for demanding industrial environments where conventional EVA foam, PE foam or standard sponge materials may not provide sufficient thermal stability.
The closed-cell silicone sponge structure combines the flexibility of rubber with the lightweight and cushioning characteristics of foam. It can be used for high-temperature gaskets, sealing pads, 열 절연, vibration isolation, cushioning and heat press applications.
Silicone sponge products are commonly available in a wide temperature range, with specifications depending on the formulation, 밀도, compression and operating conditions. Published industrial silicone sponge specifications commonly cover approximately -60°C to +200°C or higher, while specialized high-temperature grades can withstand significantly higher intermittent temperatures.
Silicone sponge rubber sheet is a cellular form of silicone rubber containing numerous small cells that give the material its soft and compressible structure.
Compared with solid silicone rubber sheet, silicone sponge provides:
Closed-cell silicone sponge is particularly useful where air and water sealing are important.
The main advantage of silicone sponge is its ability to maintain flexibility and physical performance over a broad temperature range.
Depending on the selected silicone compound and application conditions, silicone sponge sheets can be designed for continuous or intermittent exposure to elevated temperatures. Some high-temperature silicone sponge products are specified for temperatures up to approximately +270℃, with higher intermittent-temperature capability.
For this reason, silicone sponge is widely used in heat sealing, thermal shielding, 산업 장비, automotive components and high-temperature gasket applications.
Silicone rubber also performs well at low temperatures. Industrial silicone sponge specifications commonly extend to approximately -60℃, making the material suitable for applications involving significant temperature fluctuations.
This broad operating window makes silicone sponge particularly useful for outdoor equipment, transportation components and industrial machinery.
The cellular structure allows the sheet to compress easily and conform to irregular surfaces.
This makes it suitable for:
Silicone rubber has strong resistance to ozone, UV radiation, oxidation and weathering, which helps it maintain performance in outdoor and demanding industrial environments.
Silicone sponge rubber can also provide electrical insulation and is used in electronic and electrical components where thermal resistance and flexible sealing are required.
Silicone sponge rubber is widely used to manufacture flexible gaskets and seals. Its compressibility allows it to fill small gaps and compensate for surface irregularities.
Typical applications include:
Silicone sponge sheets can be used as resilient pads in heat transfer and heat press equipment. Their flexibility and temperature resistance help provide uniform contact between the heated surface and workpiece.
The cellular structure provides thermal insulation, making silicone sponge useful around components exposed to elevated temperatures.
It can be used as:
The soft sponge structure absorbs vibration and mechanical impact, making it suitable for machinery, automotive and electronic equipment.
Silicone sponge rubber can provide a combination of thermal resistance, 유연성, cushioning and electrical insulation, making it useful for selected electronic and electrical applications.
EVA foam is an excellent material for packaging, sports products, 신발류, toys and general-purpose cushioning. 하지만, silicone sponge is more appropriate when the application involves significantly higher temperatures.

Commercial silicone sponge sheets are available in multiple thicknesses and densities, and manufacturers can provide customized dimensions for different sealing and insulation requirements.
In addition to supplying silicone sponge sheets, custom fabrication can turn the material into finished components.
Depending on the design, processing options can include:
For production applications, customers can provide a 2D drawing, CAD file, sample or detailed dimensions. We can evaluate the design and recommend the appropriate material thickness, density and fabrication method.
Before purchasing high-temperature silicone sponge, 다음 요소를 고려하십시오:
Specify both the continuous operating temperature and peak temperature. A material’s maximum intermittent temperature should not automatically be treated as its continuous working temperature.
Thicker silicone sponge provides greater cushioning and insulation, while thinner sheets are easier to compress and integrate into compact assemblies.
A softer grade is suitable for low-pressure sealing and cushioning. A firmer grade may be better when greater compression resistance and dimensional stability are required.
For gasket applications, determine the available compression force and required sealing pressure. Silicone sponge can be selected according to the required compression and recovery characteristics.
Silicone generally performs well against environmental exposure, ozone and UV, but compatibility with specific chemicals must be verified before production. Certain solvents, fuels and aggressive chemicals may require a different elastomer or a specialized silicone formulation.
For OEM manufacturers, packaging companies, equipment manufacturers and industrial distributors, custom silicone sponge rubber can be supplied according to project requirements.
We can help evaluate:
For large-volume projects, custom cutting and converting can help reduce material waste and simplify assembly.
The temperature capability depends on the silicone formulation and application. General industrial silicone sponge products may operate around -60°C to +200°C, while specialized high-temperature grades can reach approximately +270°C or higher for intermittent exposure. Always confirm the technical data sheet for the specific grade before use.
Closed-cell silicone sponge has low water absorption and can provide good water and air sealing when properly compressed.
예. Silicone sponge is commonly used for gaskets, 물개, packing materials and thermal sealing applications.
예. Silicone sponge sheets can be converted into custom pads, 개스킷, strips and other shapes using suitable cutting and fabrication processes.
For applications involving elevated temperatures, silicone sponge is generally the more appropriate material because silicone has substantially better thermal stability. EVA foam is better suited to general cushioning, 포장, sports and consumer-product applications.
