PA with good mechanical properties

Polyamide is mainly used for synthetic fibers, and its most prominent advantage is that its wear resistance is higher than all other fibers, 10 times higher than cotton wear resistance and 20 times higher than wool wear resistance. Adding some polyamide fibers to blended fabrics can greatly improve their wear resistance; When stretched to 3-6%, the elastic recovery rate can reach 100%; Can withstand tens of thousands of twists and turns without breaking.  Polyformaldehyde

The strength of polyamide fiber is 1-2 times higher than cotton, 4-5 times higher than wool, and 3 times higher than viscose fiber. However, polyamide fibers have poor heat and light resistance, as well as poor retention, resulting in clothes that are not as stiff as polyester. In addition, both nylon-66 and nylon-6 used for clothing have the disadvantages of poor moisture absorption and dyeing properties. Therefore, new varieties of polyamide fibers - nylon-3 and nylon-4- have been developed, which have the characteristics of light weight, excellent wrinkle resistance, good breathability, as well as good durability, dyeing and heat setting. Therefore, they are considered to have great development prospects. AS Resin

This type of product has a wide range of applications and is a good material for replacing metals such as steel, iron, and copper with plastic. It is an important engineering plastic; Cast nylon is widely used as a substitute for wear-resistant parts in mechanical equipment, replacing copper and alloys as wear-resistant components in equipment. Suitable for producing wear-resistant parts, transmission structural components, household appliance parts, automotive manufacturing parts, screw prevention mechanical parts, chemical machinery parts, and chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, blades, screws, high-pressure washers, screws, nuts, sealing rings, shuttles, sleeves, shaft sleeve connectors, etc.  Polyformaldehyde
