Warm punching, composite grade with woven glass covers for improved flexural, tensile and impact strength. It has better electrical properties and higher mechanical strength than NP611.
NP634 is a combination of a NP611 core combined with phenolic glass cover plies. A non-NEMA grade, NP634 provides higher mechanical strength and dimensional stability than NP611.
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.
