Introduction of PA66

Polyamide 66 (PA66), also known as nylon 66, is an engineering thermoplastic that belongs to the polyamide. It is a high-performance material known for its exceptional mechanical strength, heat resistance, and versatility. PA66 is synthesized from hexamethylenediamine and adipic acid, resulting in a linear polymer structure with repeating amide groups.

 

This polymer structure contributes to its remarkable properties, making it a preferred choice for applications requiring strong and durable components, such as automotive parts, electrical connectors, industrial equipment, and consumer goods. Its high heat deflection temperature, excellent chemical resistance, and resistance to impact make PA66 a reliable material in demanding engineering applications.
