Nylacast

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.

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 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 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 Moly is a cast nylon material in which improved crystallization occurs by the addition of Molybdenum Disulphide. On account of this the superficial hardness increases (providing excellent machine ability) and simultaneously the general mechanical and anti-friction properties are improved. Due to the fact that the crystal structure breaks down immediately before the melting temperature is reached, the thermal properties of the material are improved over the basic grade.

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 PTFE is a self lubricating material with a lower friction coefficient than other material. It is a water resistant material and can operate between the temperatures of -250°C up to 250°C.

Nylacast Polyvinyl Chloride is a well established thermoplastic material. Due to its mechanical and tensile strength it is used in a large range of products and machined applications, whilst also being able to be welded and bonded. It offers excellent corrosion and weather resistance.

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.
