Polyurethane is a compact and elastic elastomer.
Formed components are usually manufactured by depressurised casting in open metallic moulds. According to the production requirements of the finished part, armouring or stiffening made of metal can be inserted.
Precipitation is effected by heat. After the component has been cast and removed, it is tempered in a thermal chamber ensuring the component’s usage properties.
Good elasticity with high structural cohesiveness. The e-module is nearly twice as high as with rubber. The working temperature lies in between -40°C and + 80°C, temporarily also up to ca. + 110°C.
