Description

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.

This material data has been provided by Norplex Micarta.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
