High Load Bearing Foam Washers

Advanced Seals & Gaskets Ltd produce thousands of washers daily using  polyurethane materials, including  High load bearing foam washers.  Polyurethane foams are one of the more commonly used materials found in everyday applications including furniture and car interiors. 

High load bearing PU raw material foams are manufactured in block form of in 2.3m x 2m or 2.3m x 1m in size, which can then be split into sheets in thicknesses up to around 100mm - but can be laminated to achieve thicknesses greater than this.  These sheets can also be joined to form rolls from which washers can be cut. 

HLB Foam washers are manufactured on-site using drawings or measurements provided by our customers, with whom we work closely 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 washers everytime.  

Depending upon the size and quantity of  washers required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one off samples to multiple thousand batch runs, which can be supplied as loosely cut parts, or kiss-cut on rolls  -  where a high quantity is required or for use on fast paced assembly lines.  Our HLB PU  foam washers can be supplied in a plain finish, laminated in layers to create greater thicknesses,  laminated to other materials or coated with a choice of self-adhesives and foils prior to the washers being cut.

    What are High Load Bearing Foam Washers?

    High load bearing foam washers are a flat ring of material with an outer diameter (OD) and inner diameter (ID) measurement, which is placed between two  surfaces creating cushioning, acting as a spacer, filtration seal/component cut as a ring shape.  HLB PU  foam washers can be produced  in a range of thicknesses from as little as around 2mm, manufacturing them inhouse means we can supply them in a plain or self adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.

    As with other Polyurethane foams,  high density polyurethane foam is generally made from two ingredients: polyol, which is petroleum-based, and diisocyanate - these two ingredients make up the basis of polyurethane foams.  HLB or high density foam washers are  popular across many industries offering excellent support and shock absorption.   HLB foams can be manufactured in varying firmness levels (this firmness isn’t to be confused with density) for use in different applications and industries which require different levels of support.

    Why Use High Load Bearing Foam Washers?

    HLB foam washers are popular due to their load bearing properties and the resistance to impact and force they offer.  As with other Polyurethane foams,  washers made using high load bearing foams can be manufactured in various densities and also grades to include Flame Resistance properties. 

    High density foam washers are popular and known for their ‘viscoelastic’ properties - i.e the materials resistance and recovery after force has been applied.

    Although HLB foams can be manufactured in varying densities and levels of firmness, hybrid foams can also be made by laminating HLB foam with other lower density materials, which allows manufactures to be able to offer bespoke levels of firmness enabling us to offer bespoke washers.

    Advantages of using High Load Bearing Polyurethane Foam Washers

    High load bearing foam washers are not only found used as mechanical and engineering components, but also in many commercial and residential seating applications.   Due to their excellent viscoelastic properties, they are also great for use in automotive applications as interior fillings,  industrial applications such as buffer or impact pads or as seals and gaskets.

    When used for packaging and transporting fragile components within the electronics market,  a large case insert or bespoke cut ring can be cut to hold products in place offering  a high level of protection and cushioning delicate items.   High load bearing foam washers are available in a choice of densities and thicknesses, but can also be laminated to other materials to offer bespoke levels of firmness. 

    HLB Polyurethane foams and washers cut from this material can be found used in a range of sound and vibration dampening applications, cushioning, sealing, impact pads and even seals or gaskets within aerospace, automotive, machinery and appliances manufacturing.
