IsoMold CMR 2001

IsoMold CMR 2001 is a two-part polyurethane molding system. IsoMold CMR 2001 is mixed 1:1 by weight and by volume. IsoMold CMR 2001 cures to a soft (Shore A 20 ± 2 ); rubber. IsoMold CMR 2001 was formulated specifically to be used to manufacture corner molds. It is also suitable when molds of detailed masters that contain some undercuts are required. Some of the most common uses of IsoMold CMR 2001 are to make molds for point-of-purchase displays; rapid prototypes; special effects; concrete casting applications; and sculpture reproductions.



  • Concrete casting applications
  • Point of Purchase Displays
  • Sculpture Reproductions


  • Convenient Mixing Ratio
  • Excellent release characteristics
  • Low shrinkage
  • Picks up fine detail in molding/casting applications
