Plastic Ball
Polyurethane Balls (PUR)
Specification Commercial name PU,PUR
Ball Diameter 1.5mm 100mm Precision Grade I
II III Mechanical Data Hardness (Shore D)
80-100 Density 1.14g/m3 Youngs Modulus
360GPa Tensile Strength 70-140MPa Service
temperatureºC -40/80
Corrosion Protection Polyurethane has good
corrosion resistance to mineral oils, greases,
petroleum products, dilute acids, and alkalis.
Strong acids and bases do not cause the balls to
resist. Poor resistance when exposed to steam,
aromatic hydrocarbons, heated, moist air, and
organic polar solvents. Application Check
valves and pumps both use polyurethane balls as
seals.In the food business, specialized bearings
and safety valves are routinely employed.

Plastic Ball
Polyvinyl Chloride Balls (PVC)
Specification Commercial name PVC Ball Diameter
1.5mm 100mm Precision Grade I II
III Mechanical Data Hardness (Shore D)
75-155 Density 1.4g/m3 Youngs Modulus
3250MPa Tensile Strength 55-90Mpa Service
temperatureºC -50/60 ºC
PVC balls are relatively hard and can be polished
to a shine. PVC balls have good chemical and
biological resistance also provide good impact
and abrasion resistance. Corrosion Protection
It is eroded by a variety of organic solvents and
is not recommended to be used above 70ºC. Poor
tolerance to aromatic and halogenated
hydrocarbons, ketones, cyclic ethers and
aldehydes. Application Used for electroplating
industry and petrochemical valves, sealing
valves, industrial equipment valves.

C
Corrosion Resistance It possesses excellent
corrosion resistance in the majority of
conditions, with the exception of sulfuric
acid-containing solutions and situations with
high alkali concentrations. Applications Special
bearing/high-speed, vacuum pump, compressor,
mechanical centrifugal, shaft/spindle,
recirculating ball screw, flowmeter, measuring
instrument. It is used in the aerospace and
military industry.
