We are Professional on Sponge rubber extrusion, closed cell sponge extrusion manufacture. Extruded sponge and high density foam extrusions materials is from expanded EPDM or neoprene, Closed cell sponge rubber extrusions profiles mainly adopt to continuous extrusion and vulcanization methods, for peroxide cured rubber or by discontinuous extrusion and autoclave (steam) vulcanization. Foam rubber and foam extrusion are soft and compressible, even though often interchangeably.

Foam extrusion, in simple terms, consists of mixing a chemical foaming agent with a polymer, and extruding the mixture at a temperature high enough to melt the polymer. The chemical foaming agent reacts or decomposes, resulting in a gas being liberated which is dispersed in the polymer melt.

Extruded gasket, foam sealing strip, Sponge seal as important sealing production, we ensure provide high quality rubber extrusion and rubber profile reasonable price to merchant.
