Description

NP572 is a high strength, medium weave glass epoxy laminate that retains a minimum of 50 percent of its room temperature flexural strength when tested at 150ᴼC and its Tg is guaranteed to be 180°C or greater. NP572 is certifiable to IEC 60216-3, IEEE STD 98-2002 and ASTM D2304 for Class H insulation in electrical devices. NP572 is also certifiable to MIL-I-24768/3, Type GEB and IEC 60893-3-2-EP GC 308 and EP GC203.
