Density Classes (Sponge Rubber)

Porosity

According to customer requirements

The Elastoform® (sponge rubber) product range has density classes ranging from 160 to 600 kg/m³ and can therefore meet every requirement. 

Due to our own recipe development we are able to fulfil special customer requirements. 

The porosities of our products range from very fine to very coarse. 

BOSIG can respond to special customer requirements in order to achieve the desired porosity together with the customer.
