Polyester heat resistance
WebHigh resistance against high energy radiation (gamma and X-rays) Polyamide 6-10 is used to manufacture insulators for the electrical market. This is because of its good insulating properties, heat resistance, and flame retardancy. Limitations of PA 6-10 include: High mold shrinkage, and high cost compared to other low water absorption polyamides. Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain.
