PA6, also known as Nylon 6, is a translucent or opaque, milky white particle.NylonHigh mechanical strength, good toughness, with high tensile and compressive strength. Tensile strength exceeds that of metal, compressive strength is comparable to metal, but its rigidity is not as good as metal. Tensile strength is close to yield strength, more than double that of ABS. Excellent absorption of impact and stress vibration, with impact strength much higher than that of general plastics and superior to acetal resins. NylonExcellent fatigue resistance; parts can maintain their original mechanical strength after multiple bending cycles. Often used in applications where cyclic fatigue is pronounced, such as on escalator handrails and bicycle plastic wheel rims.
