Nylon Tube

Nylon, also known as polyamide (PA), is a general term for thermoplastic resins that contain repeated amide groups [-NHCO]- in their molecular backbone. This includes aliphatic PA, aliphatic-aromatic PA, and aromatic PA. Among them, aliphatic PA has a wide variety, high production, and extensive applications, with its naming determined by the specific number of carbon atoms in the synthetic monomer.

Nylon boasts numerous properties, thus finding extensive application in the automotive, electrical equipment, mechanical components, transportation equipment, textile, and papermaking machinery industries. With the accelerated trend towards miniaturization in the automotive sector, high-performance electronic and electrical equipment, and lightweighting of machinery, the demand for nylon will continue to grow significantly. Particularly, as a structural material, nylon is subject to stringent requirements in terms of its strength, heat resistance, and cold resistance.

Nylon's inherent drawbacks are also significant factors limiting its applications, particularly for the two major varieties, PA6 and PA66. Compared to PA46, PAl2, and others, they possess a strong price advantage, although certain properties may not meet the requirements of certain industries. Therefore, it is necessary to enhance specific properties through modification for a particular application field, thereby expanding its scope of use. Due to PA's strong polarity, high moisture absorption, and poor dimensional stability, these can be improved through modification.
