Primary Benefits of Silicone Sponge Sheet
Wide operational temperature range: Silicone sponge can withstand temperatures between -60°C and 260°C.
Water sealing: It’s made possible by the closed cell structure, which also allows for effective water sealing with only moderate compressive stresses.
Resistance to compression set: Silicone has great resistance to compression set, particularly at temperatures that are higher.
Ozone and UV protection: Due in part to their organic structure, silicone goods have exceptional UV and ozone resistance. Long-lasting performance is provided by this.
Rugged: In situations where silicone is necessary, silicone sponge pieces are more robust than some other commercially available alternatives.
