Within in the polyamides commonly referred to as “Nylons”, below we distinguish the different types that are offered. The difference in the physical properties which exist between these types are mainly determined by the composition and the structure of their molecular chains.

The popular Nylons are 6, 66 and the MoS2 grades to which Elder Engineering hold a variety of stock levels. Contact us with your requirements.

Nylon 66 + MoS2

A grey-black product is an extruded composition of Nylon 66 plus a patented percentage of MoS2. The addition of self lubricating MoS2 renders the material somewhat stiffer, harder and dimensionally more stable than  Nylon 66, but results in some loss of impact strength. The nucleating effects of the molybdenum disulphide create an improved crystalline structure enhancing bearing and wear characteristics.

Nylon 66 + MoS2

Ertalon 4.6 (Stanyl)

Compared with the conventional nylons, ERTALON 4.6 (STANYL®)
features a better retention of stiffness and creep resistance over a wide range of temperatures as well as a superior heat ageing resistance. Therefore, applications for ERTALON 4.6 are situated in the “higher temperature area” (80 – 150°C) where stiffness, creep resistance, heat ageing resistance, fatigue strength and wear resistance of Nylon 6, Nylon 66, Acetal and PET fall short.

Ertalon 4.6 (stanyl)

Nylon 66

A material with a higher mechanical strength, stiffness, heat and
wear resistance than Nylon 6. It also has a better creep
resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatic lathes.

Cast Nylon – Heat Stabilised

Cast Nylon-Heat Stabilised is a very dense and highly crystalline structure. Compared with conventional extruded or cast nylons, this grade offers superior heat ageing performance in air (much better resistance to thermal-oxidative degradation), allowing 15 – 30°C higher continuously allowable service temperatures than standard Cast Nylon. It is particularly recommended for bearings and other mechanical parts subject to wear which are operating in air for long periods of time at temperatures over 60°C.

Cast Nylon - Heat Stabilised

Nylon 6 + Oil

This internally lubricated cast nylon 6 is self-lubricating in the
real sense of the word.  Nylon 6 + Oil, especially developed
for unlubricated, highly loaded and slowly moving part applications, yields a considerable increase for the application possibilities of nylons. This is because of its reduced coefficient of friction (up to -50%) and improved wear resistance (up to x 10).

Nylon 6 + Oil

Nylon 66 – GF30

Compared with Nylon 66, this 30% glass fibre reinforced and heat stabilised nylon grade offers increased strength, stiffness, creep resistance and dimensional stability whilst retaining an excellent wear resistance. It also allows higher maximum service temperatures.

Nylatron NSM

NYLATRON NSM is a proprietary cast nylon 6 formulation containing
solid lubricant additives which grant this material self-lubricity, excellent frictional properties, superior wear resistance and outstanding
Pressure-Velocity capabilities (up to 5 times higher than
conventional cast nylons). Being particularly suited for higher velocity, unlubricated moving parts applications, it is the perfect complement to the oil-filled grade Nylon 6 + Oil


Nylatron 703XL

A new internally lubricated cast nylon for special area application. Zero stick / slip is its differentiating feature. Units equipped with Nylatron 703XL can accurately display smaller movements made possible by today’s sophisticated control devices. static and dynamic coefficients of friction that approximate each other at virtually every point over the Nylon product’s useful range, make this possible.

Applications: Wear pads; bearing blocks; wear guides; linear bearings and bushes; any load-bearing slide application especially in start / stop functions.

Nylatron MC901

This modified cast nylon 6 grade with its distinctive blue colour exhibits higher toughness, flexibility and fatigue resistance than Cast Nylon. It has proved to be an excellent material for gear wheels, racks and pinions.

Nylon 6 + MoS2

Nylon 6 +MoS2 contains finely divided particles of molybdenum disulphide to enhance its bearing and wear behavior without impairing the impact and fatigue resistance inherent to unmodified cast nylon grades. It is a very commonly used grade for gears, bearings, sprockets and sheaves.

Nylon 6

This material offers an optimal combination of mechanical strength, stiffness, toughness, mechanical damping properties and wear resistance. These properties, together with a
favourable electrical insulating ability and a good chemical
resistance make Nylon 6 is a “general purpose” grade for
mechanical construction and maintenance.
