General Characteristics of Open Cell Silicone Sponge

 

 

Open cell silicone sponge will have a specific set of characteristics in addition to features offered by the core elastomer. Some open cell silicone sponge is very unique because it operates similar to a spring by returning to the original sate following compression. This is due to the chemical makeup of the material and the free flowing movement of air.
Breathable and soft, open cell silicone sponge can easily conform to sealing applications in comparison to closed cell foam. At the same time, open cell foams can be manufactured at both low densities and high densities. A few key highlights of open cell silicone sponge include:
● Flexibility retained even in low temperatures
● Resilient material
● Resistant to bases and acid

 

Open Cell Silicone Sponge Used
 

Gaskets and seals: Open cell silicone sponges are used to create airtight and watertight seals in various industries, such as automotive, aerospace, and electronics. They provide excellent resistance to weathering, UV radiation, and extreme temperatures. See our Custom Cut Gaskets & Seals page.

 

Cushioning and shock absorption: Open cell silicone sponges are used as padding or cushioning material in packaging, electronics, and medical devices. They can absorb shocks and vibrations, protecting delicate components or products during transport or use.

 

Thermal insulation: Due to their low thermal conductivity, open cell silicone sponges are used to insulate and protect components that are exposed to high temperatures, such as in industrial ovens, furnace seals, or engine gaskets.

 

Sound dampening: Open cell silicone sponges can be used as soundproofing material in various applications, including architectural settings, automotive industry, or HVAC systems. They can reduce noise transmission and improve acoustic isolation.

 

Electrical insulation: Open cell silicone sponges are used as electrical insulators due to their excellent dielectric properties. They can be used to cover electrical wires or components, providing protection against electrical shocks or short-circuits.
