novapress® ACTIV

Description:

• A special composite material that combines two types of rubber. Consists of a hard, oil-resistant inner layer and soft outer layers. This achieves controlled properties in contact with oils while maintaining stable mechanical properties.

Typical areas of use:

Construction of transformers and equipment
Mechanical engineering
Component parts for the automotive industry

The above technical data was obtained in laboratory conditions using standard materials. The guarantee of the functionality of the gasket joint cannot be fully ensured due to the large difference in installation and production conditions. We reserve the right to change the material if this will serve to further technical development
