Nylacast Oilon was a break through of the first magnitude in the world of cast nylons, developed in the early 70s by Nylacast and introduced to the market in 1974. Oilon was the very first authentic lubricated Nylon, havinga blended liquid lubricant system built in during the processstages, which obviously resulted in a substantial increase inbearing life, 5 times that of Natural cast nylon and 25 timesthat of phosphor bronze! The lubricant contained within thematerial will not drain, machine, spin, leech or dry out andnever needs replenishment.

Nylacast Impact is a grade specifically developed for applications requiring high impact resistance and/or noise reduction capabilities. The important characteristics of these materials are their improved insensitivity against stresses, sharp edges, notches, scratches etc. Impact is ideally suited to applications such as support rollers for the aggregate processing industry, dollies used in conjunction with piledrivers and crane feet pads as well as roller coaster wheels in relation to noise reduction. However there are many industries and applications where this type of material would be very beneficial over the basic grade of Natural cast nylon.

Nylacast PA 6 Natural is the basic PA 6 grade from which all the other grades of cast nylon stem. Generally accepted as the primary engineering polymer, natural cast nylon is suitable for virtually any plain bearing application, not to mention a huge range of other applications for which this versatile grade finds a use. By varying the conditions of polymerisation the mechanical properties of cast nylon may be altered to suit specific applications and the performance of the basic polymer can be enhanced with the addition of various additives, fillers, lubricants and colorants (see further grades). Compared with injection molding and extrusion grades of polyamide, cast nylons stand out with their improved mechanical, thermal and chemical resistance properties.

Nylacast Nylanite is an unreinforced, self lubricating, semi-crystalline thermoplastic polyester, demonstrating dimensional stability similar to Acetal, combined with the comparable wear resistance of nylon. Heavily loaded mechanical precision components subjected to sustained abrasive environments are particularly suited to this material.

Nylacast Polyethylene is well known in the polymer family and is often referred to as PE. It has an extremely low coefficient of friction, good chemical and corrosion resistance with excellent impact strength making it an extremely adaptive thermoplastic. Polyethylene is available in various grades, offering different properties.

Nylacast Polypropylene is a light weight copolymer material with high impact ,stress cracking and chemical resistance. Not only does this material offer these characteristics but also exhibits great flexibility and toughness at low temperatures with low moisture intake.

Nylacast H.S Blue is heat stabilized cast nylon, easily distinguished by its blue color. Additives in the form of high temperature resistant colorants, heat stabilizers and UV stabilizers allow HS Blue to better retain its mechanical properties in applications operating at higher temperatures.

Nylacast Aquanyl PA 6/12 is a copolymer of nylon 6 and nylon 12 produced via the anionic polymerization process using the monomer’s of caprolactam and Laurinlactam. Laurinlactam has a similar effect to a plasticizer, but being a copolymer does not suffer the “Leeching out” problems of many plasticisers. The aim is to impart a greater degree of resilience to the material, for which purpose the copolymerisation method is very successful.

Nylacast Peek is a high performance engineering thermoplastic. It is very strong and rigid. The characteristics of PEEK show that it has the highest tensile strength in the plastics family. It can be used on a continuous basis in temperatures of 480°F (250°C) without any loss of its properties.

Nylacast Nylube was introduced into the Nylacast product rangein 1989 as a logical progression to Oilon with already outstanding performance as a bearing material. Since that time, it has proved to be Nylacast’s supreme wear resisting grade and one of the most important developments from Nylacast in new materials. Nylube contains a combined liquid/solid lubricant system which allows for a coefficient of friction as low as 0.08. This is below that of almost any other polymer available at present.
