Plastic balls of various specifications

The acrylic resin is a colorless, cylindrical granule with a smooth surface; the particle size ranges from 2 mm to 5 mm in any direction, and it contains no mechanical impurities. The powder is an off-white, free of agglomerates;合格品 may exhibit a slight yellowish tint. Polypropylene resin is non‑toxic, with a density of 0.90–0.91 g/cm³, making it one of the lightest among general‑purpose plastics. It exhibits excellent mechanical and heat‑resistance properties, with a service temperature range of –30°C to 140°C. Additionally, it boasts superior electrical insulation and chemical stability, virtually non‑hygroscopic, and chemically inert when exposed to most chemicals. However, it is corrosive when in contact with fuming sulfuric acid, fuming nitric acid, chromic acid solutions, halogens, benzene, carbon tetrachloride, chloroform, and similar substances.

Detailed Introduction

The acrylic resin is a colorless, cylindrical granule with a smooth surface; the particle size ranges from 2 mm to 5 mm in any direction, and it contains no mechanical impurities. The powder is off-white, free of agglomerates, though a slight yellowish tinge is permissible in conforming products. Polypropylene resin is non‑toxic, with a density of 0.90–0.91 g/cm³, making it one of the lightest among general‑purpose plastics. It exhibits excellent mechanical properties and heat resistance, with a service temperature range of –30 to 140°C. Additionally, it offers superior electrical insulation and chemical stability, virtually non‑hygroscopic, and chemically inert when exposed to most common chemicals. However, it is corrosive when in contact with fuming sulfuric acid, fuming nitric acid, chromic acid solutions, halogens, benzene, carbon tetrachloride, chloroform, and similar substances.

Polypropylene resin, with a density of 0.90–0.91 g/cm³, is one of the lightest among commodity plastics. It boasts excellent mechanical properties and heat resistance, with a service temperature range of –30 to 140°C. We welcome both new and existing customers to call us for inquiries and procurement.

Plastic balls are primarily categorized by material into: PP plastic balls, POM plastic balls, PA plastic balls, PMMA plastic balls, ABS plastic balls, PS plastic balls, PE plastic balls, nylon plastic balls, solid plastic balls, hollow plastic balls, and foam‑filled plastic balls. These balls exhibit high hardness and rigidity, excellent stress resistance, superior wear resistance, self‑lubrication, fatigue resistance, as well as high density and a high degree of crystallinity. Their precision ranges from ±0.02 to 0.001 mm, with no parting lines and exceptionally smooth surfaces, making them ideal for a wide range of applications. Plastic balls are widely used in industries such as automotive, sensors, valves, pumps, sanitary ware, electronics, ball valves, bearings, and electrical appliances. Available sizes for PP, POM, PA, and PE plastic balls include 3.175, 3.97, 4.0, 4.76, 5.56, 6.35, 8.00, 9.52, 10.0, 12.7, 15.87, 19.05, 25.4, and 35.2 up to 100 mm. With their outstanding precision, we deliver superior quality and service to our customers. We warmly welcome domestic and international partners to discuss business opportunities and inquire about our plastic ball products.
