F.R.Warren Plastic Supply, Fabrication and Engineering

Nylon

we supply in Nylon in Rod , Sheet and Tube in different colours and thickness.

Nylon is supplied in two main forms cast and extruded.

Nylon 6 Extruded

Nylon 6 Cast

Nylon 66 Extruded

Nylon 12 Extruded

The most common colours are natural (off white appearance) and black, other colours are available such as green, yellow and blue – these colours are used to signify different types of nylon such as

Blue – MC901 Heat stabilised Nylon used when extreme temperature differences are requested of the product.

Green – Oil Filled Nylon for less friction

Yellow –  For reduced water absorption and improved stability and impact strength.

POLYAMIDE
Polyamide, also known as Nylon or Kevlar, tend to be semi-crystalline and are usually very tough materials, Polyamides have good chemical and thermal resistance. Polyamides cannot withstand long exposure to moisture and can distort if exposed. The flexibility and impact resistance however does tend to improve the more moisture the Polyamide takes on. Polyamides tend to have good resistance to most chemicals, but can be affected by strong acids, alkalis and alcohols. Polyamides can be used in high temperature environments. The properties of Polyamides make the material an ideal replacement for metals in applications like industrial valves, automotive parts, insulators and many other applications that require high strength, weight reduction and toughness.
Polyamide PA 6 and PA 66 are the most commonly used forms of Polyamides. These two Polyamides are quite similar but both have distinct advantages over each other. PA6 can be used at a lower temperature; the material itself is lightweight and has a much lower mould shrinkage. PA6 has a very smooth finish and is mostly used in high impact applications where tougher material is needed e.g. Firearm and automotive components and for things like gears in the engineering industry.
Polyamide PA 66 hard and tough PA 66 is characterised by its high resistance, rigidity and toughness. PA 66 based materials have a melting point of 262 °C. PA 66 is often used in automobile and machine construction where components are subject to high mechanical and thermal exposure.
There are quite a few more Polyamide grades, soft and flexible PA 12 is characterised by its high impact strength, excellent abrasion and surface slip characteristics. The melting point of PA 12 is the lowest amongst the important Polyamides at around 180 °C. PA12 also has a lower water absorption which adds to its dimensional stability and flexibility as well as being more resistant to stress cracking.
