Flexible Polyurethane Elastomers
Elastomeric Casting Resins are high quality PUR systems with a wide range of shore hardness levels (Shore A 40 to D 67) used in manifold application areas.
The tough elastic systems are mainly used for high abrasion resistant liners (face casting process) for core boxes and match plates with long working life.
