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.
Car manufacturing Used in the manufacture of fuel filters, fuel filters, tanks, traps, oil storage tanks, engine cylinder head covers, radiator water tanks, balanced rotating shaft gears. Can also be used in automotive electrical accessories, terminals and so on. In addition, it can be used as drive, control, etc.
Electrical and electronics industry It can be used to make electric rice cookers, electric vacuum cleaners, high-frequency electronic food heaters, terminal posts, switches and resistors for electrical products.
Medical equipment Used for medical blood transfusion, blood collection, infusion set, etc. PA monofilament can be used for surgical sutures, wigs, etc. In addition, digital rotary disks of electronic typewriters, binding posts, transmission gears, belt filters of printing machines, etc.
Other aspects Used for making disposable lighters, alkaline dry battery pads, motorcycle driver’s helmets, office machine housings, angle wheels, seats and backs of office chairs, skates, fishing lines, etc. PA film has excellent gas barrier properties, It has good oil resistance, low temperature impact resistance and penetration resistance, and can be used for packaging frozen foods such as meat and ham sausage. Polyamide can also be rods and plates, also used as gears or other transmissions.
