Import 9mm 12mm 12.7mm Pp Plastic Solid Balls — Buy in Bulk from Supplier in China

These PP plastic solid balls are precision-moulded polypropylene spheres available in diameters of 9mm, 12mm, and 12.7mm, with a density of approximately 0.85g/cm³. The material offers inherent chemical resistance to acids, alkalis, alcohols, salt solutions, oils, greases, and most solvents, while maintaining excellent electrical insulation properties with a low dielectric coefficient. Supplied in grades G0 to G3, they meet dimensional tolerances of ±0.01 to ±0.05mm, making them suitable for applications requiring consistent floating behaviour or calibration accuracy.

Polypropylene is a thermoplastic with the highest melting point in its class, and these balls are non-porous with low water absorption, which prevents degradation in wet environments. Typical industry use includes fluid level indicators, medical devices like blood transfusion components, and calibration tools where buoyancy and chemical inertness are critical. The material is standard for food-grade and industrial applications, though it is not resistant to aromatic hydrocarbons or chlorinated solvents.

Common buyers include manufacturers of laboratory equipment, medical devices, and industrial flow systems, particularly where lightweight, corrosion-resistant, and electrically inert components are required. The supplier, based in Taian, Shandong, can facilitate sample orders for testing, with mass production lead times of 2 to 3 weeks for larger quantities. Buyers should confirm compatibility with their specific chemical environment, as polypropylene’s resistance varies by compound.

Taian Porei Import & Export Co., Ltd. is based in Taian, Shandong Province, China, operating from an address on Dongyue Road. The company specialises in the supply of plastic components, including precision-moulded polypropylene products, and maintains a response framework for sample and bulk enquiries. While the supplier’s profile does not list active response metrics, it explicitly welcomes sample orders for quality testing, including mixed samples for evaluation.

The supplier’s trade process begins with a buyer specifying requirements or applications, followed by a quotation tailored to those needs or the supplier’s recommendations. Once samples are confirmed, a deposit secures the formal order, with production arranged thereafter. The company supports multiple shipping methods, including express couriers like DHL, UPS, FedEx, or TNT, as well as air and sea freight, with typical sample lead times of 3 to 5 days and mass production requiring 2 to 3 weeks for larger orders.
