Material Notes:
Cast nylon 6 produced with the addition of graphite and a special lubricator which gives to this product better properties than natural PA6G. Whilst retaining the general features of OMNIAMID G it is more shock resistant and self-lubricating. It is also easier to machine and U.V. ray resistance is better than that of natural Omniamid.Features:Wear resistance: better than natural PA6Tensile stress and compressive strength: same as Omniamid G, whilst the shock resistance is higher, the fatigue resistance is more elevated.Self-lubricating: the friction coefficient is lowAgeing resistance: weatherproof and good resistance at low temperatureBlack colourWeak Point:It is hygroscopic even if to a lower extent than natural PA6G. Because of the molecular structure, large-sized cast pieces have better quality than those of small dimensions.Application:Mechanical: thanks to its good mechanical features and the possibility to obtain large-sized pieces, this material is mainly used to produce large diameter gears, pulleys, wheels and anti-wear guides. Due to the excellent abrasion resistance it is used in the building of parts for construction machines, excavators and earthmovers to produce gear wheels, guide bearings, bearings, sliding bearings etc. In the shipbuilding industry its improved weather resistance makes it suitable for rollers, haulage, sliding guides, bearings. In cable-car systems its uses include pulleys, wheels and sliding blocks.Food contact: it cannot be used in contact with food.Electrical: usage in the electrical field is to be avoided as the electrical properties change with the change in moisture content. It is sometimes used when its mechanical features are requested.Chemical: it is resistant to alkali, inorganic compounds and solvents.Information provided by Omnia Plastica s.p.a. for semifinished products such as sheet, rod, and tube.
