Polyurethanes ECOPUR, G-ECOPUR, H-ECOPUR, S-ECOPUR, T-ECOPUR, X-ECOPUR
Polyurethanes are thermoplastic elastomers which demonstrate the characteristics of elastomers over a wide temperature range and in addition have the processing behaviour of thermoplastics. They can be melted at high temperature and can be processed with traditional thermoplastic processing techniques. Polyurethanes offer outstanding mechanical properties like wear restistance.

Elastomers NBR, HNBR, FPM, XNBR, EDPM, Silicon rubber
Elastomers, respectively rubber materials are polymers, which are chemically cross-linked by the vulcanization process. Due to their chemical bonds, they do not melt, but rather begin to decompose at high temperatures.

Thermoplastics PTFE PA PEEK POM
Thermoplastics include standard and special hard grade materials with outstanding wear resistance for mechanical applications and top performance PTFE compounds with highest chemical and temperature resistance, optimized for sealing applications and Advanced Engineered Plastic Parts (AEPP). Most of the materials comply with FDA regulations.
