Description

It is a specially designed long-chain polyphthalamide (PPA) that combines a low water absorption and excellent mechanical properties over a broad temperature range. Depending on the grade the key features are: Mechanical properties at high temperature, low water absorption, outstanding fuel barrier, heat resistance, a low friction coefficient, Low wear, chemical resistance, long term heat resistance, high reflectivity, less color change by heat and light, high flowability

This material data has been provided by M-Base.

"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.
