PA66(polyamide 66 or nylon 66), compared with PA6, PA66 is more widely used in the automotive industry, instrument shells and other products requiring impact resistance and high strength.
Polyamide resin, English name is polyamide, short for PA. Commonly known as Nylon, it is a general term for polymers containing amide groups in the backbone repeat unit of macromolecules. Among the five engineering plastics, it has the largest output, the largest variety and the widest use. The main varieties of nylon are nylon 6 and nylon 66, which occupy an absolutely dominant position. Nylon 6 is polycaprolactam, while nylon 66 is polyhexanediamine adipate, nylon 66 is L2 % harder than nylon 6; Followed by nylon 11, nylon 12, nylon 610, nylon 612, in addition to nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, new varieties of nylon 6I, nylon 9T and special nylon MXD6(barrier resin), etc., a large number of modified varieties of nylon. Such as reinforced nylon, monomer casting nylon (MC nylon), reaction injection molding (RIM), nylon, aromatic nylon, nylon, transparent high impact (super tough nylon, nylon, conductive plating nylon, flame retardant nylon, nylon and other polymer blend and alloy, etc., meet the special requirements and widely used for metal, wood, such as traditional material substitution
