The Nylon Family


Science and Discovery

Nylon is a synthetic plastic material that is composed of polyimides of high molecular weight. Nylons were first developed during the early 1930’s by a research team, headed by an American chemist, Wallace Carothers. The team originally set out to research commercial application for polymers. Carothers and the team made the polymer by combining hexamethylenediamine, a crystalline substance that easily bonds with acids, with atopic acid. Wallace produced what is now known as Nylon 66 (one of the most common and popular variants). The demand of nylon and synthetic materials grew in World War II when natural items like silk, rubber, and latex were short in supply.

Nylon today

Nylon is a synthetic thermoplastic linear polyimide and is used in a wide range of applications. Some of these include toothbrushes, umbrellas, fishing line, toilet brushes, guitar strings, cable sheaves, gears, medical implants and more.

Nylon Properties

As polyamides, Nylon 6 & 66 have their own separate and distinct benefits, yet, they do share the same core properties. Within this family, the most important ones are: Nylon 6, Nylon 66, Nylon GS and Nylon GS. Some of their main characteristics are as follows:

  • Wear Resistance
  • High Strength & Toughness
  • Large Size Capabilities
  • Custom Castings
  • Minimal cost
  • Heat Resistance to 100°C

The Nylatron family

There are different grades available in nylon, each having its own unique properties and characteristics, most of which are available at Ai Plastics and Mitsubishi Chemical Advanced Materials. These include:

Nylon GSM

Nylatron GSM contains finely divided particles of molybdenum disulphide that enhance its bearing and wear behaviour without impairing the impact and fatigue resistance to unmodified cast nylon grades.

It is commonly used for gears, bearings, sprockets and sheaves.

Nylatron GS

Nylaytron GS comes in the form of a sheet and rod at Ai Plastics and has good mechanical and electrical properties. Nylatron GS is an ideal balance of strength and toughness. With the added filler of Molybdenum disulphide (MoS2), it helps improve the crystalline structure, bearing and wear properties.

It is commonly used for gears, bearings and pulleys.

Nylatron 6

Nylon 6 is a general purpose grade for mechanical construction and maintenance due to its optimal combination of strength, stiffness, mechanical damping properties and wear resistance combined with a good electrical insulating ability and chemical resistance.

It is commonly used in applications of mechanical engineering, aerospace technology, electronics and the automotive industry.

Nylatron 66 Natural

Nylatron 66 (also known as nylon 66) is known for its rigidity, abrasion resistance and thermal dimensional stability. It is suitable for machining on automatic lathes and has been used in a wide range of applications ranging from electronics, marine and automotive industry to forestry, construction and mining.

The difference?

Whilst Nylon 6 and Nylon 66 are very similar in properties, they still vary a little in terms of chemical structure. Nylon 6 is made from one monomer which has 6 carbon atoms whilst Nylon 66 is made from 2 monomers, each having 6 carbon atoms.
