Precision balls manufactured with plastic materials have several advantages regarding steel balls. They present a high resistance to corrosion being at the same extremely light and they have a good resistance to heat. They are also very appropriate in the applications where it is necessary a noise reduction and lubrication is not required.
This material presents an excellent resistance to wear and impact with a low coefficient of friction. The approximate maximum temperature resistance is 100ºC. It resists usual solvents, hydrocarbons, low strength alcohols and acetone.
Similar to nylon, it presents a bigger density.
Material of high density and resistance to the temperature (aprox. 250ºC). Non inflammable. It resists almost all chemical and solvent products.
Low density material, 0.8 grams / cm³, floats partially submerged in water. With good mechanical characteristics, balls made of this material are excellent electrical insulators. Service temperature: - 30 +110 ºC.
TORLON: Excellent mechanical characteristics due to its high toughness. Resists up to 200 ºC. Widely used in nautical applications.
POLYURETHANE (PUR): Plastic with similar characteristics to rubber but with greater resistance to wear and abrasion.
