Nylon-66 - English name is Polyadiohexylenediamine, which is called nylon 66 in China's chemical fiber industry. Its scientific name is polyhexamethylene adipamide. It is a translucent milky white crystalline polymer, insoluble in general solvents, only soluble in m-cresol, etc. The mechanical strength and hardness are very high, and the rigidity is very high. Most of this product is non-toxic, but when the monomer content in the resin is too high, it is not suitable for long-term contact with skin or food. Countries often have food hygiene regulations for this. Nylon 66 should be stored in a tightly closed and dry environment.
Nylon 66 is widely used in the fields of engineering plastics, civil silk, and high-strength industrial silk. In industry, nylon 66 is widely used to make various mechanical, automotive, chemical, electronic, and electrical components, especially suitable for high-strength or wear-resistant parts, such as various gears, rollers, sliding wheels, roller shafts, bearings, impeller in pump bodies, fan blades, high-pressure sealing rings, valve seats, gaskets, bushings, various shells, tool handles, support frames Cable cladding, car lampshade, etc.
