Silicone sponge extrusion Manufacturers in China
Properties of Silicone Sponge Extrusions
1）Silicone rubber can withstand extreme temperatures, usually between -60°C to +250°C (-76°F to +482°F).
2）Silicone sponges are highly flexible and can be compressed or bent without losing their effectiveness, making them ideal for sealing applications where flexibility is needed. And can retains its shape well even after being compressed over long periods.
3）Silicone sponge extrusions are light, the lowest density is 0.3g/cm3.
4）Silicone sponge is resistant to ozone, UV, and outdoor environmental conditions, making it perfect for outdoor use or applications exposed to sunlight.
5）The material is non-conductive, offering excellent electrical insulation properties, which makes it ideal for sealing sensitive electronic components.
Usage of Silicone Sponge Extrusions
1）Used for doors, windows, and HVAC systems.
2）Prevent dust, water, and air from entering electrical enclosures, protecting sensitive components.
3）Seal food processing equipment, ensuring no contamination.
4）Medical equipment may use silicone sponge for cushioning, sealing, or vibration damping, especially in devices requiring biocompatibility.
