Chemicals company Lanxess, which makes glass fiber materials, has developed Vibrathane 7085, a new, polyester-based prepolymer for hot cast elastomers. It has MDI end groups (methylene diphenyl diisocyanate) and cures with 1,4-butanediol to polyurethane cast elastomers, with a low compression set and a high tear strength at hardnesses of 83 to 87 Shore A.

Possible applications for the material include die cutting blankets and anvils, bushings for torque rods of trucks, buses and trailers, and noise-damping shaking screens for ore processing.
