RIM Materials

Polyurethane, the material for all applications. Virtually no other material combines aesthetics, ergonomics and function in such an ideal form.

PUR material systems from the leading raw material manufacturers Covestro and BASF are used at Thieme.
The materials are purchased as preformulated systems and processed into high-quality shaped part.
