PP plastic balls are made of Polypropylene (PP) material, which is a lightweight, highly ductile thermoplastic polymer with excellent chemical resistance, heat resistance and good mechanical strength. PP material has low density and excellent wear resistance, and is widely used in a variety of industrial and living fields.
| Name | PP plastic ball |
| Grade | G0-G3 |
| Tolerance | (±0.01mm-0.05mm) |
| Density | 0.85g/cm³ |
| Performance | 1. Polypropylene has low density (lower than water) 2. Low water absorption 3. Higher melting point (in thermoplastics) 4. Excellent insulation performance, low dielectric coefficient 5.
