Material	Polypropylene Balls(PP)
Size	Φ2.381mm-Φ38.1mm
Grade	G0-G3 (±0.01-0.05mm)
Density	Around: 0.85g/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, withblood 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 (±0.01-0.05mm)
Density	Around: 1.1g/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

Material	DELRIN Balls (ACETAL RESIN-POM)
Size	Φ2.381mm-Φ38.1mm
Grade	G0-G3 (±0.01-0.05mm)
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
Applications	POM ball table and drawer slide device is typically used, bearings, rollers, valves, and electronic apparatus, sailing apparatus.

Material	Balls-PTFE
Size	Φ2.381mm-Φ38.1mm
Grade	G0-G3 (±0.01-0.05mm)
Feature	Based frictionless known material having excellent chemical stability, resistance to corrosion, sealing, high lubricity non-tackiness, electrical insulation and good anti-aging Stamina. Continuous use temperature range of -180 ° C to 350 ° C. PTFE , ball so excellent frictionless known to most corrosive resistant possessed electrically insulating material,
Applications	Particularly suitable for use in cryogenic liquids and acids under the conditions of the instrument.
