Acetal balls offer predictable mechanical, chemical and electrical properties over a broad temperature range for extended periods of time. They exhibit good fatigue resistance, impact resistance, tensile and shear strength and dimensional stability. They have very low moisture absorption characteristics. Delrin balls maintain a natural lubricity, giving them a low coefficient of friction against metals.
Most resins used for these balls meet Other names include polyoxymethylene (POM) and polyacetal.
Delrin is a DuPont product: Celcon is a Hoechst Celanese product.
Material | DELRIN Balls (ACETAL RESIN-POM) | ||||
Size | Φ0.91mm—Φ100mm | ||||
Grade | G0-G3 (±0.01-0.12mm) | ||||
Density | Around: 1.4g/cm3 | ||||
Feature | Performance: it is similar to nylon, but slightly harder than nylon, slightly larger than the density recommended products applied to the required low water absorption | ||||
Color | Available color red blue green black orange etc | ||||
Applications | Spray agitators, light safety valves, low load bearings. Special pumps and valves, sliding rails for furniture, fluids flow check devices, medical instruments. They are used in foodstuff, chemical, electronic, pharmaceutical industry. | ||||

Material | Polypropylene Balls(PP) | ||||
Size | Φ2mm—Φ100mm | ||||
Grade | G0-G3 (±0.01-0.12mm) | ||||
Density | Around: 0.88g/cm3 | ||||
Feature | Has good resistance, chemical resistance, low density (density less than water), low water absorption, the highest melting point of the thermoplastic with excellent electrical insulator and low dielectric coefficient, often used for floating capacity requirements, with blood transfusion, level calibration indicator. It has a high resistance to chemical substances, such as acid, alkali, alcohol, many inorganic substances, salt solutions, solvents, gasoline, water, oil, grease, cleaning agents, fruit juices, milk and the like, but not resistant to aromatic carbon hydrogen compounds and chlorate....... | ||||
Applications | PP ball is mainly used for transfusion, level calibration indicator. | ||||
Material | Nylon Balls (Zytel®, Polymide--PA66) | ||||
Size | Φ2.381mm—Φ38.1mm | ||||
Grade | G0-G3 (±0.01-0.12mm) | ||||
Density | Around: 1.14g/cm3 | ||||
Feature | The nylon has preferably the alkali metal, to adapt to the neutral characteristics of petroleum products and all kinds of chemical products. | ||||
Applications | Used in check valve, light load, the knob pull switch, low-cost, but also for better flexibility requirements, high hardness aspects | ||||
