Description

Fine weave (less than 4 ounce/square yard) cotton fabric commonly called linen, combined with phenolic resin to provide better machining than BP11NPN. BP21NPN should be used for smaller and more intricate shapes than BP11NPN, when a finer surface finish is required.

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.
