COMPOSITIONS FOR VIBRATION DAMPING

摘要

A vibration damping composition including (a) at least one saturated thermosettable component such as a polyurethane precursor, or an epoxy resin having one or more epoxy groups; (b) a crosslinking agent for the saturated thermosettable component; and (c) a thermoplastic interpolymer resin such as a alpha -olefin/vinyl aromatic interpolymer, for example an ethylene-styrene interpolymer (ESI); wherein the glass transition temperature of the cured saturated thermosettable component is between -20 DEG C and +100 DEG C; and the vibration damping composition provides efficient damping at 0-60 DEG C with a maximum damping factor >15 percent that is stable at 0-30 DEG C.
