This article systematically analyzes the core characteristics of PA materials such as tensile strength (\uff1e60MPa) and wear resistance coefficient (0.15-0.4), compares its cost-effectiveness with metal materials, and reveals the influence mechanism of its water absorption rate (saturated 8%) on performance through DuPont laboratory data. Combined with BASF\u2019s latest technical report, this article discusses how glass fiber reinforced PA66-GF30 can increase the heat deformation temperature to above 250\u2103, providing a decision-making basis for engineering material selection.<\/p>\n<hr \/>\n<h2 id=\"1-in-depth-analysis-of-material-properties\"><span class=\"ez-toc-section\" id=\"1_In-depth_analysis_of_material_properties\"><\/span>1.
