PA66 vs PBT: Key Differences for Automotive Parts
Selecting the right engineering plastic is critical in automotive injection molding. Among commonly used materials, PA66 (Nylon 66) and PBT (Polybutylene Terephthalate) are widely applied in structural and functional automotive components. Although both are engineering thermoplastics, they differ significantly in heat resistance, mechanical strength, and dimensional stability. Heat Resistance Heat resistance is one of the…
