Nylon Sheet and Nylon Rod have become the most well known engineering plastics due to their excellent properties. Nylon rod and sheet act as an all rounder product and are capable of many situations, being a safe and dependable plastic.
Nylon sheets, plates, tubes or rods within the polyamides, are commonly referred to as "nylon", each with distinguishable differences between the types. The most important ones are: Nylon PA 6, PA 66, PA 11 and PA 12. The differences in physical properties which exist between these types of nylons are mainly determined by the composition and the structure of their molecular chains.
Nylon 6 is perhaps the most popular used nylon grade used throughout Europe due to its properties, and Nylon sheet is particularly easy to machine, be it through automated machines or manual machinery. Ertalon and Nylatron are the brand names for Nylon 6 and Nylon 66 grades.
What is the difference between cast and extruded Nylons?
The main difference lies in the manufacturing process. Cast polyamide products are manufactured by means of a chemical reaction process. This allows products with extremely large dimensions and custom cast parts to be manufactured. Water absorption and dimensional changes are lower in CAST. The crystallinity is greater so that wear resistance and machinability are better. Extruded absorbs more moisture and is thus tougher and has greater impact and vibration damping properties.
The initial aim is to increase values for strength and rigidity, especially at high temperatures. The plastic becomes harder and has lower elongation, i.e. it is less elastic and breaks when strained. Improved dimensional stability and tighter tolerances can be achieved. The coefficient of thermal expansion is significantly lower. In some cases there are similarities with aluminium or steel. During machining operations the fibre additives cause increased tool wear.
Nylatron® NSM nylon offers up to 10 times longer part life than standard type 6 nylon in this pivot bushing on a mining dump truck. (Prior material: Bronze)
Nylon offers better wear resistance, compressive strength and fatigue resistance than other materials in a variety of wear applications. (Prior materials: Steel, Aluminium, UHMW-PE, Injection Molded Nylon)
Wear pads made of Nylatron® NSM nylon are light weight, able to support heavy loads, are non-abrasive to mating surfaces. (Prior material: Bronze and cast iron covered with UHMW-PE)
Gears made of Nylatron® NSM nylon run quieter and wear longer without the need for lubrication on processing equipment. (Prior materials: Bronze and steel)
MC® 901 is custom cast to size saving fabrication time and money in this port cap and diffuser nozzle application. It also weighs only 1/7 the former parts making parts easier to handle and install. (Prior material: Stainless Steel)
Nylons can absorb up to 9% (by weight) water under high humidity or submerged in water. This results in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.

Ertalon 6 SA (PA 6) 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 Ertalon 6 SA a "general purpose" grade for mechanical construction and maintenance.
Ertalon 66 SA (PA 66) is material with a higher mechanical strength, stiffness, heat and wear resistance than Ertalon 6 SA. It also has a better creep resistance but its impact strength and mechanical damping ability are reduced. Well suited for machining on automatic lathes.
Ertalon 66-GF30 PA 66-GF30), when compared with virgin PA 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 max. service temperatures.
Nylatron GS (PA 66 + MoS²). The addition of MoS² renders this material somewhat stiffer, harder and dimensionally more stable than Ertalon 66 SA, but results in some loss of impact strength. The nucleating effect of the molybdenum disulphide results into an improved crystalline structure enhancing bearing and wear properties.
Ertalon 6 PLA (PA 6). Unmodified cast nylon 6 grade exhibiting characteristics which come very close to those of Ertalon 66 SA. It combines high strength, stiffness and hardness with good creep and wear resistance, heat ageing properties and machinability.
Ertalon 6 XAU+ (PA 6) is a heat stabilised cast nylon grade with a very dense and highly crystalline structure. Compared with a conventional extruded nylon or cast nylon, Ertalon 6 XAU+ offers superior heat ageing performance in air (much better resistance to thermal-oxidative degradation), allowing 15 - 30°C higher continuously allowable service temperatures. Ertalon 6 XAU+ is particularly recommended for bearings and other mechanical parts subject to wear which are operating for long periods of time at temperatures over 60°C.
Ertalon LFX (PA6 + oil). This internally lubricated cast nylon 6 is self-lubricating in the real meaning of the word. Ertalon LFX, especially developed for unlubricated, highly loaded and slowly moving parts applications, yields a considerable enlargement of the application possibilities of nylons. This because of its reduced coefficient of friction (up to -50%) and improved wear resistance (up to x 10).
Nylatron MC901 (PA6) is a cast nylon 6 with a distinctive blue colour, it exhibits higher toughness, flexibility and fatigue resistance than Ertalon 6 PLA. It has proved to be an excellent material for gear wheels, racks and pinions.
Nylatron GSM (PA6 + MoS²) is a cast nylon 6 containing finely divided particles of molybdenum disulphide to enhance its bearing and wear behaviour 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.
Nylatron NSM (PA6 + solid lubricant) 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 Ertalon LFX.
