FLAME RETARDANT EPOXY PREPREGS, LAMINATES, AND PRINTED WIRING BOARDS OF ENHANCED THERMAL STABILITY

摘要

Boehmite (alumina monohydrate) when used with a typical epoxy resin advanced with phosphorus makes it possible to improve thermal stability and to increase the ignition time of laminates formed from prepregs made using this fortified resin. Such laminates have exceptionally high thermal stability and showed similar longer times to ignition as compared to corresponding resins in which alumina trihydrate was used.
