Reconstituted Foam Washers
Reconstituted Foam Washers
Advanced Seals & Gaskets Ltd convert and manufacture thousands of Polyurethane washers, in a choice of colours and grades, in both foam and solid variants. One such grade of PU washer supplied by ASG are those cut from reconstituted polyurethane foam. Reconstituted Polyurethane foam is recognised by other names within the industry including ‘recon’ foam, crumb foam or chip foam, recognisable by its multi-coloured appearance and rough, fuzzy texture.
Reconstituted PU foam materials are manufactured in very large master blocks or ‘buns’ usually around 2 metres x 1.5 metres in size and over 1 metre in height, which are held in stock ready to be carved and split into sheets or split and joined into rolls from which washers can be cut. Reconstituted foam washers are manufactured on-site using drawings or measurements provided by our customers, to ensure the final product is to their exact specification.
Depending upon the size and quantity of washers required, one of many presses or CNC machines can be used to manufacture the final product - from one off samples to multiple thousand batch runs, we have a machine designed to quickly and accurately produce perfectly formed Crumb foam washers everytime. On-site conversion facilities means we can quickly use blocks of stock material to produce recon PU washers in a plain or self adhesive finish, loosely packed or kiss cut on rolls for ease of use and application.

What are Polyurethane Reconstituted Foam Washers?
Recon Foam washers are flat rings with an outer diameter (OD) and inner diameter (ID) measurement, cut from sheets or rolls of material which are placed between two surfaces creating a level surface, acting as a spacer, seal or between nuts and bolts to spread the pressure when tightened. Reconstituted Polyurethane (PU) or crumb/chip foam is a recycled material produced using a mixture of various grades of polyurethane foam off-cuts which would have otherwise been discarded. This mixture of foam is fed through a shredder which chips the material down into small pieces, and then compresses and binds them together producing a huge multi-coloured block of material, which can be cut down into sheets or used to convert into finished washers.
Why use Reconstituted Polyurethane Foam Washers?
Customers often take washers cut from reconstituted foam for a number of reasons - the material itself is affordable, compact, highly resistant and most of all good for the environment as it is recycled and the material would have otherwise ended up in landfill sites!!! Recon foam washers can be cut or pressed from rolls or sheets of material and be used in applications where there will be repeated use and impact such as within seating, fitness pads and mats and in packaging or noise and vibration reduction applications. Reconstituted foam washers are available in different weights (strengths), usually between 4lb and 14lb suited to varying levels of use.
Prior to cutting into washers, foam sheets can be laminated with a choice of foils and self-adhesives applied to one or both faces. For very thick washers or where a combination of properties are required, the foam can be laminated together in layers or can be laminated to other materials for use within more specialist applications when composite materials are needed.
Advantages of using Reconstituted Polyurethane Foam Washers
Chip foam washers are desirable for general use as they are made using a cost-effective and eco-friendly material which is made from recycled off-cuts. Washers cut using Recon foam can often be used for cushioning, sound and vibration control in industries such as automotive, audio, sports and leisure, aerospace, marine, rail, and domestic manufacturing sectors.
Even though raw Reconstituted polyurethane materials are made using waste from a mixture of different types of PU foams, it can still be produced and supplied in a choice of weights (strengths) by adjusting how much the chips are compressed during production allowing it to be used in various applications. Using our state of the art equipment and master buns of material, we are able to produce washers in various sizes and thicknesses using saws and presses, available in a plain finish or coated with a choice of foils and self adhesives.
