High Performance PTMEG Series

Bcc PTMEG series of high performance two-component MDI elastomers when processed and cured at elevated temperatures can give you the performance of a standard hot-cast prepolymer.  The PTMEG series, when used with BC 8590A isocyante, cures to a range of hardness from 60-95 Shore A, giving mechanical testing values far above standard room temperature systems.
