Polypropylene balls (PP balls) are featured by low weight, excellent heat resistance, excellent electric insulation. Thus, the application of polypropylene balls is now in expanding on automobile, home electric appliances and many other areas. Our polypropylene balls are made of polypropylene. This is a thermoplastic synthetic resin with excellent properties, which has good heat resistance, electrical insulation, and wear resistance. And it’s a lightweight, easy-to-recycle material. Therefore, since its inception, it has been widely developed and applied in many fields such as machinery, electronic appliances, construction, textile, packaging, and so on. Our products have a uniform ball shape, precise processing, low water absorption, and no welding marks. After multiple production steps such as multiple grinding and fine polishing, the balls are very delicate.
