NP500A High-Performance Epoxy Sheet: NEMA G-10 Grade, MIL-I-24768/2 Certified

NP500A is constructed of a woven glass fabric combined with easy-machining, non-brominated epoxy resin. It is engineered to provide NEMA grade G-10 properties, but is easier to machine and more cost effective in many applications. NP500A meets or exceeds the requirements of MIL-I-24768/2 and IEC 60893-2-EPGC 201.
