Description

NP500CR consists of a glass fabric with a specially formulated epoxy resin system resulting in excellent electrical characteristics and superior physical properties at cryogenic temperatures (-270°C to 135°C operating temperature range). It has very low thermal conductivity and has been produced specifically for use in cryogenic applications.

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.
