The materials used are the decisive factor when it comes to the properties of our products. The material selected from a wide range of possible options (compounds) depends on the various use scenarios, required temperature ranges, media resistance, approvals, etc. We work with all standard materials in the industry such as NBR, EPDM, FPM, VMQ, FVMQ, HNBR, ACM and CR across the entire Shore hardness scale.
In cooperation with our customers, we can also offer or develop custom compounds.
