Nylon (PA) refers to a plastic composed of polyamide resins. This type of resin can be prepared by condensation of diamines and diacids, or by ring opening polymerization of lactams formed by dehydration of amino acids. Unlike PS, PE, PP, etc., PA does not gradually soften with increasing heating temperature, but rather softens within a narrow temperature range close to its melting point, which is very obvious at 215-225 ℃. Once the temperature is reached, flow occurs.
There are many varieties of PA, mainly including PA6, PA66, PA610, PA11, PA12, PA1010, PA612, PA46, PA6T, PA9T, MXD-6 aromatic amides, etc PA6, PA66, PA610, PA11, and PA12 are the most commonly used
Nylon engineering plastics appear as crystalline resins with keratin, toughness, shiny surface, white (or milky white) or slightly yellow, transparent or semi transparent in appearance, and are easily colored in any color. As an engineering plastic, the molecular weight of nylon is generally between 15000 and 30000. Their densities are slightly greater than 1, with a density of 1.14-1.15g/cm3. Tensile strength:>60.0MPa. Elongation rate:>30%. Bending strength: 90.0MPa. Gap impact strength: (kJ/m2)>5.
The shrinkage rate of nylon is 1% to 2% Attention should be paid to the dimensional changes in moisture absorption after molding. The water absorption rate is 100%, and it can absorb 8% when it is relatively saturated with moisture The operating temperature can be between -40 and 105 ℃. Melting point: 215-225 ℃. The mechanical properties of PA with a suitable wall thickness of 2-3.5mm, such as tensile and compressive strength, vary with temperature and moisture absorption. Therefore, water is a plasticizer for PA. After adding fiberglass, its tensile and compressive strength can be increased by about 2 times, and its temperature resistance can also be correspondingly improved. PA itself has a very high wear resistance, so it can be operated continuously without lubrication. If you want to achieve special lubrication effects, sulfides can be added to PA.
