A different molecular structure, chemical; nylon molecular backbone containing repeating amide groups of-[NHCO]-thermoplastic resin collectively. Polypropylene yarn and polypropylene fibers.
Second, characteristic differences in performance;
Nylon for toughness angle-shaped translucent or milky white crystalline resin, as engineering plastics such as nylon molecular weight is generally 1.5-30,000. Nylon with high mechanical strength, high softening point, heat resistance, low coefficient of friction, wear-resistant, self-lubricating, shock absorbing and noise reduction, oil resistance, resistance to acid, alkali and solvents in General, good electrical insulation, self-extinguishing, nontoxic, odorless, good weather resistance, poor staining properties. Disadvantage is that water-absorbent, affect dimensional stability and electrical properties of fiber reinforced resin can be reduced water absorption, making it able to work under high temperature and high humidity. Nylon and fiberglass affinity are very good. Often used to make Combs, toothbrushes, hook, fan, bag rope, fruit bags and so on. Non-toxic, but not long-term contact with acid and alkali.
