RIM materials

Reaction Injection Molding

Polyurethane, the material for all applications. Hardly any other material combines aesthetics, ergonomics and function in this ideal form.

Thieme uses PUR material systems from the leading raw material manufacturers Covestro and BASF.
The materials are purchased as pre-formulated systems and processed into high-quality molded parts.

The material offers

  • economic efficiency
  • Freedom of design
  • High dimensional stability
  • High rigidity
  • Low weight
  • Impact resistance
  • Sound absorption
  • Good thermal properties
  • Chemical resistance
  • Flame retardant according to UL Subject 94
  • Recyclability

Advantages of PUR
