Sponge rubber extrusion creates a cellular structure with interconnected air or gas-filled cells. It can provide cushioning, flexibility, and compressibility.
Sponge rubber exhibits excellent compression and recovery properties. So it can compress under pressure and quickly regain its original shape after release.
Sponge rubber profiles offer inherent thermal and acoustic insulation properties. It can reduce heat transfer and sound transmission.
Sponge rubber profiles are highly flexible and conform to irregular surfaces or contours. It can ensure proper fit and sealing.
Sponge rubber exhibits resistance to moisture, water absorption, and certain chemicals. It is suitable for humid or wet environments and contact with certain substances.
The sponge or foam rubber profiles suit various. Industries and applications, including automotive, construction, HVAC, electronics, packaging, and more. They are used for sealing applications (gaskets and weatherstripping), insulation, cushioning, soundproofing, shock absorption, and vibration dampening.
Sponge rubber extrusions are commonly made of neoprene, EPDM (ethylene propylene diene monomer), silicone, and polyurethane. When selecting the material, it depends on the properties. Such as density, hardness, temperature, and chemical resistance.
The working temperature of sponge rubber extrusion depends on the specific type of rubber material used in the manufacturing process. Here are the approximate working temperature ranges for some used sponge rubber materials:
