NP130 (NEMA FR-4) consists of a woven glass fabric substrate combined with a halogenated epoxy resin system. It is produced to printed circuit board quality standards, is flame retardant and meets or exceeds the requirements of MIL-I-24768/27, Type GEE-F, and IPC 4101, sheet 21.
The Safety Data Sheet (SDS) (formerly Material Safety Data Sheet (MSDS)) includes information such as the physical, health, and environmental health hazards of the material.
Brominated epoxy resin systems used in FR-4 and FR-5 materials were originally created to stop or retard potential fire hazards caused by over-heating or electrical failure resulting in arcing. While HBr is very effective at flame retardation, the resulting white smoke (HBr) can corrode copper, standard grade mild and stainless steels and most other metals. In 1998 NEMA updated their standards to differentiate G-10 and G-11 from FR-4 and FR-5. This update specifically excludes the use of bromine or other halogen flame retardants in the production of G-10 or G-11.
