NPEB-400 is a brominated epoxy resin, which is manufactured from tetrabromo bisphenol-A and epichlorohydrin.It provides excellent flame retardant because of high bromine content. NON FLAMABLE, however the excellent properties in physics and electronics are the same as BPA-ECH types.Recommended for use in electrical mould- ing and lamination applications where fire resistance is essential.
NPEB-400 is a brominated epoxy resin from Nan Ya, manufactured from tetrabromo bisphenol-A and epichlorohydrin. Its high bromine content (46–50%) gives it strong flame-retardant properties, while its physical and electrical properties otherwise match standard BPA-ECH (bisphenol-A/ epichlorohydrin) epoxy resins. It is recommended for electrical molding and lamination applications where fire resistance is essential.
