RIM Molding Materials

Thieme Corporation molds polyurethane (PUR) material systems. Polyurethane is the material used for all of our part applications. Virtually no other material combines aesthetics, ergonomics and function in such an ideal form.

Generally, PUR material systems from the leading raw material manufacturers Bayer and BASF are used at Thieme. The materials are purchased as preformulated systems and are processed into high-quality parts.

Thieme Corporation consistently molds the following polyurethane material systems:
