PA12 plastic ball has similar characteristics to PA11 plastic ball, but the crystal structure is different. PA12 plastic ball is a good electrical insulator and will not affect the insulation performance due to moisture like other polyamides. It has good impact resistance and chemical stability. There are many improved varieties of PA12 plastic balls in terms of plasticizing properties and strengthening properties. Compared with PA6 and PA66, these materials have a lower melting point and density, and a very high moisture regain. PA12 has no resistance to strong oxidizing acids. The viscosity of PA12 mainly depends on humidity, temperature and storage time. It is very fluid. The shrinkage rate is between 0.5% and 2%, which mainly depends on the material variety, wall thickness and other process conditions. PA12 plastic ball polyamide 12 or nylon 12 Typical application range: water meter and other commercial equipment, cable sleeves, mechanical cams, Sliding mechanism, photovoltaic backplane and bearing, etc.

Polyamide resin, the English name is 1olyamide, or PA for short. Commonly known as nylon (Nylon), it is a general term for polymers containing amide groups in the repeating units of the macromolecular chain. Among the five major engineering raw materials, it has the largest output, the most variety, and the most versatile variety. The main varieties are nylon 6, nylon 66 plastic balls, nylon 11 plastic balls, nylon 12, nylon 610 plastic hollow balls, nylon 612 plastic hollow balls, nylon 46 plastic balls, nylon 1010 plastic balls, etc., of which nylon 6, nylon 66 production The largest, accounting for more than 90% of nylon production. Nylon 11 and nylon 12 have low temperature toughness. Nylon 46 has excellent heat resistance and has been developed rapidly. Nylon 1010 is a unique variety of my country using castor oil as raw material.
