What Is Pa66?

What is PA66 made of?
Polyamide PA66 or nylon 66 was first synthesized in 1935 and began production in 1938. It is one of the most commonly used thermoplastics for cable tie production. It is made by polycondensation of hexamethylenediamine and adipic acid (two monomers, each containing 6 carbon atoms). Its molecular structure is as follows:

Polyamide PA66 has high strength performance, high hardness and deformation stability and higher heat resistance. It belongs to linear polyamide like polyamide 6. But polyamide PA66 has lower water absorption and higher heat resistance. The melting temperature of PA66 is about 260 °C. And it can keep its shape continuously at temperatures up to 180 °C and temporarily keep its shape at 200 °C.

Application: Polyamide PA66 is widely used in the production of plastics for engineering and technical tasks such as textile industry, automobile manufacturing, machinery manufacturing industry, electrical products, household appliances, sports equipment, etc.
