Description

Bleached linen with melamine resin system. NP329 provides better arc resistance than NP320E. Also, resistant to ammonia based refrigerants. Hard, durable material should be heated to punch, but machines very well with standard machining equipment.

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.
