PA6 Chinese name polyamide, English name (abbreviated as PA), is the main molecular chain containing repeated amide group - [NHCO] - thermoplastic resin. Its name is determined by the specific number of carbon atoms of the monomer, such as nylon -6, 66, 1010, and so on.
The utility model has the advantages of high crystallinity, high melting point, high surface hardness, wear resistance, small friction coefficient, self lubrication and sound insulation. Low temperature performance, good heat resistance (can be used below 100 degrees). Non-toxic, odorless, mildew, self extinguishing, good weather resistance, but poor dyeability.
Is the largest chemical industry company in the United States - the famous chemist Carlo Seth and his research team.
Nylon series is the most important engineering plastics. The product is widely used, covering almost every field, is the five most widely used varieties of Engineering plastics.
Currently on the market commonly used extruded nylon board mainly has the following:
1: Nylon 6 (white): the material has the best comprehensive performance, including mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These properties, together with good electrical insulation and chemical resistance, make nylon 6 a "generic" material used in the manufacture of mechanical structural parts and parts.
2: Nylon 66 (cream): compared with nylon 6, the mechanical strength, rigidity, heat resistance and wear resistance, better anti creep properties, but the decrease of impact strength and mechanical damping performance, very suitable for automatic lathe machining.
3: Nylon 4.6 (red brown): compared with ordinary nylon, nylon 4.6 is characterized by rigid save strength, good creep resistance, in a wide range of temperature, the more heat aging, therefore, nylon 4.6 for nylon 6, nylon 66, POM and PET in stiffness, creep resistance, heat aging fatigue strength and wear resistance of the high temperature field is not up to the requirements of "" (80 -150 C)
4: nylon 66+GF30 (black): compared with pure nylon 66, the nylon filled with the addition of 30% glass fiber reinforced, its heat resistance, strength, stiffness. Creep resistance and dimensional stability, wear resistance and other properties are improved, the maximum allowable temperature.
5: nylon 66+MOS2 (black): this nylon filled with MoS2, compared with nylon 66 and its rigidity, hardness and dimensional stability are improved, but the impact strength decreased, MoS2 grain formation improves the effect of crystal structure, the material bearing and wear resistance were improved.
Good aging resistance, good mechanical damping capacity, good sliding properties, excellent abrasion resistance, good machining performance, precision for effective control, creeping phenomenon, good wear resistance, good dimensional stability.
Gears and parts of anticorrosive equipment. Wear resistant parts, transmission parts, household electrical appliances parts, auto parts, screw rod to prevent mechanical parts, chemical machinery parts, chemical equipment, etc..
