Q What precision and sizes are available for PP plastic balls?
APP plastic balls achieve G10-G200 precision (tolerances ±0.0025mm to ±0.025mm) with a surface finish of Ra 0.02-0.05μm. Sizes range from 0.5mm to 150mm, available in solid or hollow forms.
Q How do PP plastic balls perform in different temperatures?
AWith a thermal expansion coefficient of 11.5-12.5×10⁻⁶/°C and a melting point of 160-171°C, PP plastic balls remain stable from -10°C to 110°C, suitable for varied industrial conditions.
Q Can Polypropylene (PP) plastic balls be customized?
AYes, PP plastic balls can be customized for size, color, solid or hollow design, and surface treatments (e.g., UV-resistant coating or chrome plating) to meet specific application needs.
Q How durable are Polypropylene (PP) plastic balls?
APP plastic balls offer Shore D 70-80 hardness, tensile strength of 30-40 MPa, and high fatigue resistance, ensuring durability in low-to-moderate load environments. They withstand impacts and continuous use up to 110°C.
Q What are Polypropylene (PP) plastic balls made of?
A
Polypropylene (PP) plastic balls are made from a lightweight thermoplastic polymer (density 0.90-0.91 g/cm³) with excellent chemical resistance. They are non-toxic, FDA-compliant, and often include UV stabilizers for outdoor use.
