HPE industrial elastomers

from 40 Shore A to 55 Shore D.

COLD-CURING for small and massive parts
very high Wearproofness and Durability
  • Offers high mechanical properties with a curing at room temperature or in an oven
  • Good chemical resistance, suitable for submarine or engine environments
  • Very versatile from tiny seals to massive concrete moulds, from wheels to vehicle hoses and from hand casting to industrial production with 2-component mixing machines

space

Great chemical resistance
  • Adapted to underwater environment even in very deep conditions
  • Resistant to regular engine fluids
  • Used for wearproof concrete moulds

space

Upscale mechanical properties
  • Stronger than TPU, approaching the performance of hot cast elastomers
  • High level of durability with increased abrasion and tear resistance, even on notched parts

space

Versatile ways of processing for higher user-friendliness
  • Low exothermic reaction for any part size
  • Can be hand-casted or used in a two-component mixing machine
  • Various curing options: in an oven for faster curing, at room temperature for big parts

space

sustainability meets performance
  • The formula is adapted to hand casting with no need to handle heated materials
  • Low rate of free monomers for a safer use of the isocyanates
