Product Details

20 mm plastic balls


Plastic ball (POM)

Material

DELRIN Balls (ACETAL RESIN-POM)

Size

φ1.0mm-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.


Plastic ball (PP)

Material

Polypropylene Balls(PP)

Size

φ1.0mm-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, 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.


Plastic ball (PA)

Material

Nylon Balls (Zytel®, Polymide--PA)

Size

φ1.0mm-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
