Reinforced Reaction Injection Molding (R-RIM)

In R-RIM, short reinforcing fibers (glass, carbon, wollastonite) or fillers are added to the polyol component before processing. The PU mixture is poured into the closed mold, where it cures quickly.


  • Dimensional stability and inherent stiffness even at high temperatures
  • Excellent impact strength
  • Higher design freedom of components
  • Good paintability, even at temperatures up to 180 ┬░C, inline painting is possible
  • Low mold investment
  • Low cavity pressure enables low clamping force
  • The use of recycled carbon fibers and hollow glass microspheres enable weight savings of up to 30%
