ESTHERM™ MOLDING COMPOUND

Estherm™ Molding Compound is accomplished by use of ATSP’s high glass transitiontemperatures (up to 310℃ unfilled) and high thermal stability vitrimer resins.Vitrimers are thermosets that due to possessing exchangeable bonds within theirbackbone chain have plasticity and bonding enabled at temperatures above their glasstransition temperatures. This allows fully cured thermosets to be molded and producechemically contiguous components that have excellent structural, tribological, andthermo mechanical properties.
