Custom Polyethylene Washers.
AS Rubber & Plastics is a UK-based converter and supplier of custom polyethylene washers for construction, electronics, automotive and other industrial sectors. With 60 years of expertise, we stock a range of polyethylene foam grades suited to cushioning, spacing and vibration control, available cut to size or supplied as bespoke washers to your exact specification.
What Are Polyethylene Washers?
Polyethylene washers are flat, ring-shaped components cut from closed-cell PE foam, placed between fixings and surfaces to provide cushioning, spacing or vibration isolation.
Their closed-cell structure resists water absorption, helping them retain their performance in damp or moisture-exposed environments.
They're specified wherever a compressible, moisture-resistant spacer is needed, including:
Protecting components from vibration and impact during assembly or transit
Creating a barrier against dust and moisture ingress
Supporting insulation in HVAC, electronics, white goods and glazing assemblies
Cushioning and spacing components in packaging, engineering and yellow goods equipment

Supply Options for Polyethylene Washers.
Material Only
For businesses with in-house cutting capabilities, we supply polyethylene foam material only, in your required grade, density and thickness.
Cut to Size Sheets and Rolls
Our conversion capabilities allow us to supply polyethylene foam cut to size in sheets or rolls, ready for onward processing or die-cutting.
Custom Cut Washers
Where a finished part is required, we produce bespoke polyethylene washers cut to your exact diameter, hole size and thickness, supplied ready to use.
Adhesive Backed Washers
For applications requiring a self-adhesive fix, polyethylene washers can also be supplied with an adhesive backing, removing the need for separate fixings or additional bonding at your end.
