Plastic Ball
Material: Plastic
Size: 1.0mm-30mm
Grade: G1~G3
Certificate: ISO9001, TS16949, ISO14001
Feature: excellent fatigue and corrosion resistance, impact strength and in many cases natural lubricity
Application: For crafts, accessories, household toolsPolyamide (Nylon) Balls (PA)
Profile
Nylon balls are insoluble in diluted mineral acids and most organic acids, and common solvents. Nylon balls are exceptionally resistant to alkalis, petroleum oil and greases at temperatures up to 300°F. Acids such as lactic acid, photographic solutions, etc., have little or no effect.
Nylon balls are an excellent choice for applications that require a lightweight, resilient and abrasion-resistant material that performs well in hot, chemically aggressive and humid environments. Used without lubrication, nylon balls provide greater toughness and ductility than most plastics.
Nylon balls are also an environmentally favorable choice, because of the way they are made, and can be reused.

Hardness
R119Polypropylene Balls (PP)
Profile
Polypropylene balls have excellent chemical resistance and low density, as well as the highest melting point of the volume thermoplastics. Polypropylene balls also have high tensile strength. They are an excellent electrical insulator, with low dielectric constant and loss factors. Polypropylene balls are highly resistant to acids, alkalis, alcohols and many inorganic chemicals, and are non-toxic.

Polyoxymethylene (POM) Balls
Profile
Polyoxymethylene (POM) balls offer predictable mechanical, chemical and electrical properties over a broad temperature range for extended periods of time. Polyoxymethylene (POM) balls exhibit good fatigue resistance, impact resistance, tensile and shear strength and dimensional stability. They have very low moisture absorption characteristics.
Polyoxymethylene (POM) balls maintain a natural lubricity, giving them a low coefficient of friction against metals. Because of this, polyoxymethylene (POM) are used in pump, valve, slide and rolling applications. Most resins used for polyoxymethylene (POM) balls meet FDA, USDA and UL requirements.

Zhongshan Qianrun Precision Steel Ball Co., Ltd. is a leading manufacturer of precision steel balls in China. Products include stainless steel ball, chrome steel ball, carbon steel ball, glass ball, ceramic ball and plastic ball. Available size is from 0.5mm to 50.8mm. The technology have advanced rapidly through several years' efforts, the grade precision finally reaches G5. It is a qualitative leap so that Q. R. Company fill missing technology in domestic market.
Our precision steel balls are widely used in bearing, lithium battery, micro motor, precision tool, automobile part, precision instrument, medical equipment and cosmetic industry. 70% products export to worldwide buyers, 30% for domestic industrial customers. Because of high quality and good service, Q. R. Constantly gets customers approval and the high praise. Here we would like to thank all of their supports to accompany us grow together.
Customer supreme and best service is our aim. Q. R. Is a reliable steel ball manufacturer and certificated with ISO9001: 2008, ISO14000, TS16949. Meanwhile, we have applied for technology patent for our own designed roller soring machine HRT-1201, which being 4 times efficiency compare with traditional machine, but 1/4 labor cost only. This new machine is designed by totally enclosed type, shapely and clean, good dustproof design & high-efficiency working performance.
