Nylatron Washers

Nylatron Washers

Plastics are a popular choice for washer conversion and are one of the many materials supplied by Advanced Seals & Gaskets Ltd, available in numerous grades, colours, and thicknesses. One of these is Nylatron, a trade name for a specific type of plastic within the Nylon family. Nylatron is commonly used in engineering and machinery applications due to its strength, wear resistance, and self-lubricating properties.

Nylatron plastic is available in sheet form up to 100mm thick and in tube form, from which washers can be cut. It can also be cast into thicker sheets or bespoke sizes for custom washer production. Machined Nylatron washers can be manufactured onsite using CNC oscillating knives, saws, or presses, and can be supplied with a choice of adhesive tapes or foils for additional functionality.

    What are Nylatron Washers?

    Nylatron washers are flat, ring-shaped components used between surfaces or joints to reduce friction, prevent unsteadiness, and create a level surface for nuts, bolts, or other fixings. They can also act as water- or air-tight seals.

    Nylatron washers are made to order, based on customer samples, drawings, or dimensions, detailing Outer Diameter (OD), Inner Diameter (ID), and Thickness. They can be supplied in plain or self-adhesive finishes. Nylatron is a modified form of Nylon plastic, formulated with additional additives to enhance properties such as wear resistance, mechanical strength, and sliding performance. Many grades include Molybdenum disulfide, a dry lubricant that reduces friction and improves washer durability.

    Why use Nylatron Washers?

    Nylatron washers are chosen for their versatility and high-performance properties. They are available in a variety of grades, including unfilled, glass fibre-filled, oil-filled, internally lubricated, heat stabilised, and fibre reinforced, offering high mechanical strength, wear resistance, self-lubricating properties, and sound electrical insulation. Nylatron washers are often used as lightweight, durable alternatives to metal washers, with excellent corrosion resistance.

    Grades of Nylatron Plastic Available

    Nylatron washers can be manufactured in multiple grades, each suited to specific applications:

    • Nylatron GSM: Anthracite-colored, enhanced load-bearing and impact resistance.

    • Nylatron GS: Anthracite-colored, more rigid material with improved wear resistance, but reduced impact resistance.

    • Nylatron NSM: Grey cast nylon with solid lubricant additives, self-lubricating with superior wear and frictional properties for moving parts.

    • Nylatron MC901: Blue-colored, offering fatigue resistance, strength, and flexibility.

    • Nylatron 4.6: Brown/red variant, with excellent stability, creep resistance, wear, and ageing performance, even at high temperatures.

    Benefits of Using Nylatron Washers

    • Excellent sliding properties; some grades are self-lubricating

    • Electrical insulation

    • High wear resistance

    • Outstanding mechanical strength

    • Fatigue resistance

    • Chemical and corrosion resistance

    Advantages of Using Nylatron Washers

    Nylatron washers are ideal for demanding industries such as engineering, electrical appliances, and machinery manufacturing. They provide enhanced sliding, mechanical, and wear resistance, further improved with molybdenum disulfide additives. This lubricant enhances thermal performance without affecting chemical or electrical properties.

    While standard Nylon washers are widely used, Nylatron offers a tougher, more robust alternative for applications requiring durable, long-lasting washers. Nylatron washers can be cut from sheets or tubes or cast to bespoke sizes. They are beneficial where a lightweight, non-corrosive alternative to metal washers is needed, or where access to machinery parts is limited, reducing the risk of contamination while maintaining performance.
