Sponge rubber

Characteristics

Our sponge rubber convinces through its numerous application possibilities and provides both firmness and elasticity as well as abrasion resistance. 

The material consists of vulcanised natural rubber, is predominantly open-pored (especially small densities: application as floating boards for plasterers, cleaning rollers) to closed-pored (vacuum lifting systems).

Pore levels are available from very fine to coarse (depending on the application), volume weight classes are produced from 160 kg/m3 to 180/200 kg/m3, 250/270 kg/m3, 300/350 kg/m3, 500 kg/m3 and 600 kg/m3 as standard. 

Standard colour is orange, numerous special colours are possible.

Sponge rubber can be produced to meet any of your requirements. We sell spheres for cleaning pipework of any type, rollers as pressure rollers in various machines and of course blanks for industrial use.
