Specialist Silicone Rubber Manufacturer

Trancy cellular silicone rubber includes silicone foam and sponge. Silicone foam is made from a liquid silicone rubber, have a smooth surface on one or both surfaces. It may be closed cell, open cell or a combination of open and closed cells, which tends to be softer, lower in density. Silicone sponge is compounded with a gum type silicone. It is a closed cell structure with a characteristic of fine fabric impression on the skin surfaces.

Silicone foam and sponge feature flame retardant, low smoke, vibration suppression and shock absorption, continuing sealing requirements. They suit for sealing, isolating, confinement, and shock absorption. Therefore, they are widely used in many industries, such as communication, electronics, vehicle, rail, aerospace, energy, food, marine, construction, furniture, etc.


  • Flame Resistance:  the highest UL flame rating of UL94V-0 offers world-class fire protection.
  • Continuing Sealing: super sealing with low density and thickness tolerance and excellent resilience.
  • Shock Absorption: protect electronics and vehicles effectively due to exceptional vibration insulation.
  • Electrical Insulation: superb electrical insulation improves electrical shock strength.
  • Heat Insulation: withstand extreme temperatures and enable consistent performance in extreme temperatures from -70℃ to 260℃.
