Plastic balls are manufactured using standard and special polymer resins in diameters from 1MM -150MM.Using plastic balls it is possible to replace stainless steel or metal balls in several industrial applications at a lower price.
Plastic balls offer an advantage in terms of extremely low specific weight which means extreme lightness. They are also highly heat-resistant and grant the highest silentness during operation, thus they are noiseless and friction-free when running and don’t require any lubrication when compared with traditional metal balls.
Another important feature is the excellent oxidation and abrasion resistance; even in highly corrosive environments their usage allows a long product life. Moreover they are thermal and electrical and not magnetic insulators. It is possible to choose the most suitable type of synthetic material between wide range of plastics which possess different features.
This material is Insoluble in common solvents, alkalis, dilute mineral acids and acid organic substances. It is highly resistant to alkalis, oils and petrol greases at temperatures till 150°C, inorganic salt solutions, aromatic hydrocarbons, low alcohols, petrol, ether, petrol mixtures, mineral oils. It has high resistance, rigidity and hardness properties.
Derlin (Acetate Resin, Pom)
Polymer resins which offer excellent mechanical and chemical resistance and good electrical properties. They are resistant to inorganic salt solutions, aliphatic, aromatic and chlorinated hydrocarbons, low alcohols, ether, petrol mixtures, mineral oils and greases. These balls are often used in linear sliding guides of tables and drawers, in furniture bearings, rolls, valves and electronic components.
It has an excellent chemical resistance, low specific weight (lower than water’s one) and the highest melting point between thermoplastic materials. It is an excellent electrical insulator and it has a low electrical constant coefficient. It is often used when floating on fluids is required. Highly suitable for blood transfusion equipment, level gauges, roll-on deodorants. It is highly resistant to chemical substances like acids, alkalis, alcohols, petrol, water, oils, greases, cleansers, fruit juices, milk. It is not resistant to aromatic and chlorate hydrocarbons. It is perfectly suitable for all medical and pharmaceutical applications.
It is exceptionally resistant to most industrial acids, inorganic salt solutions, caustic substances, cryogenic fluids and hydrocarbons. There isn’t any solvent which can damage it. It is self-lubricating and recommended for all those types of uses which require a high chemical resistance.
It has low density compared to other plastic materials and it is extremely suitable for floating. It is characterized by a high sturdiness and remarkable resistance to lengthening, together with optimal electric and dielectric properties. It absorbs little water, it has a high chemical resistance, it resists diluted acids, alkalis, solvents, alcohols, fuel, water, greases and oils. It doesn’t resist to oxidizing acids, ketone, aromatic or chlorate hydrocarbons and detergents. It is an odorless material and there are no contraindications for food use.
