The production of plastic ball material mainly includes POM polyacetal, PA66 nylon, PP polypropylene, PE polyethylene, PTFE, PTFE, etc. The following is the material property table of the plastic ball.
1. The material property table of POM plastic ball, the specific gravity g/cc is 1.42, the hardness is 120, the wear resistance coefficient kg f/cm2 is equal to 0.37, the water absorption rate is equal to 0.22-0.25, and the heat distortion temperature is 160-170 degrees. POM plastic balls features high rigidity, high mechanical strength and high self-lubricity.
2. Material properties of PA66 plastic ball, the specific gravity g/cc is 1.14, the hardness is 110, the wear resistance coefficient is equal to 0.18, the water absorption rate is equal to 8.4, and the heat distortion temperature is 180-230. PA66 plastic ball has high wear resistance, fatigue resistance and high strength.
3, PP plastic ball material property table, specific gravity 0.91, hardness 90, wear resistance coefficient 385-560, water absorption rate 0.03, heat distortion temperature 120. PP plastic ball electric appliance has high insulation, light weight and high tensile strength.
