Good product, good way


PA has good comprehensive properties, including mechanical properties, heat resistance, abrasion resistance, chemical resistance and self-lubrication, and has a low coefficient of friction, a certain flame resistance, easy processing, suitable for glass fiber and Other fillers are filled and modified to improve performance and expand application range.


Polyamide (PA) is commonly known as nylon (Nylon), English name Polyamide, it is a general term for polymers containing amide groups in the repeating unit of the main chain of the macromolecule. Polyamides can be obtained by ring-opening polymerization of lactams, or by polycondensation of diamines and diacids. Polyamide (PA) refers to a polymer containing a polar amide group (-CO-NH-) in the main chain.


1. Excellent mechanical properties. Nylon has high mechanical strength and good toughness.
2. Good self-lubricity and friction resistance. Nylon has good self-lubricity and a small coefficient of friction, so that it has a long service life as a transmission component.
3. Excellent heat resistance. Such as nylon 46 and other highly crystalline nylons have a high heat distortion temperature and can be used at 150 ° C for a long period of time. PA66 passes
After the glass fiber is reinforced, its heat distortion temperature reaches above 250 ° C.
4. Excellent electrical insulation performance. Nylon has high volume resistance and high breakdown voltage resistance. It is an excellent electrical and electrical insulation material.
5. Excellent weather resistance.
6. Water absorption. Nylon has high water absorption, and saturated water can reach more than 3%. A certain extent affects the dimensional stability of the part.
