Polyurethane Seals

Advanced Seals & Gaskets Ltd are one the UK’s leading converters and suppliers of Rubber Polyurethane Seals, working with worldwide materials, one of which includes Solid Polyurethane.  

Solid Polyurethane is part of the synthetic polymer family and is a popular rubber found used in a range of industries, it’s a high performance rubber, abrasion resistant and extremely durable.  Standard industrial grade Polyurethane rubber is usually available from stock in 60° shore and 80° shore hardnesses and in translucent and black colour options, other hardnesses available to order range from 5 shore to 95 shore.  

Due to a vast production capabilities we are able to supply the highest Polyurethane Seals taking the forms of gaskets, washers, O-rings, mouldings and extrusions, which are all designed for the purpose of preventing leaks or the ingress of air, fluids and gas. 

All our seals are made to order and are produced using samples or drawings provided by customers to ensure the final product perfectly fits the application.  As each form of seal needs to be manufactured using a different process, ASG have invested heavily  in various machinery meaning we can offer high or low quantities at the most competitive price.

    What are Solid Polyurethane Seals?

    A Solid Polyurethane Seal is a generic term for a often taking the form of cut gaskets, strips, washers, extruded or moulded profiles and edge trims.   

    Solid Polyurethane is an extremely durable synthetic rubber material offering strength and abrasion resistance.  Solid Polyurethane can be manufactured in roll or sheet form which can be taken in full, or alternatively converted by way of sawing, die cutting and milling.  Alternatively for products which can’t be cut from sheet or when a specific colour is requested, bespoke mouldings and extrusion are also available to order.  

    Why use Solid Polyurethane Seals?

    Solid Rubber Polyurethane Seals can be found used as a gap filler between surfaces,  acting  as a separator or a barrier to prevent liquids, particles  or gases escaping or penetrating the application and in a number of vibration dampening, sealing and insulating applications. 

    Along with the strength and durability offered by Solid Polyurethane, other properties include good ageing, chemical, oil, grease and solvent resistance.  

    Solid Polyurethane Seals in comparison to other rubber materials, have a higher tear resistance, better high load bearing capabilities, energy absorption - sound and vibration and does not discolour as easily.  Solid Polyurethane offers a working temperature range of -30°C to +80°C, is available in range of standard thicknesses up to 100mm, can be made to order in a choice of hardnesses from 5 to 95 shore, colours  and profiles, often used to manufacture many consumer and industrial products such insulation, automotive seats, kitchen appliances, mattresses, rollers, to name but a few.

    Alternative Grades of Solid Rubber

    Advanced Seals & Gaskets work with a wide network of material manufacturers and suppliers, giving our customers more choice when looking for solid rubber, our most popular grades include:

    • Neoprene (CR) is one of our most popular solid rubber materials, with various thicknesses  held in stock.  Neoprene is suitable for use where there is exposure to grease, oil, acids, ozone and even sea water.
    • EPDM (Ethylene Propylene Diene Monomer) another very popular solid rubber is great for use in outdoor applications.  This material is resistant to water, UV, ozone, weather, abrasion, alkalines, ketones and diluted acids.
    • Nitrile (NBR) rubber is a popular solid material for use within the automotive industry where there is contact with petroleum, oil and grease.
    • SBR (Styrene-butadiene rubber) is a cost effective, commercial grade, general purpose rubber with good abrasion resistance, tensile strength and low compression set. (not sure use with petrol and chemicals).
    • Silicone (SI) is an excellent electrical insulation material which can operate at high and low temperatures.   Silicone rubber performs well when exposed to UV, weathering, ozone and moisture, and is available in a range of colours.
    • Viton rubber materials are manufactured for more demanding applications where there are harsh chemicals and high temperatures present.  Viton rubber offers resistance to fluids, oils, acids and petroleum based liquids.

    Benefits of Using Solid Polyurethane

    The type of solid rubber seal used will depend on the industry, environment and application it is going to be used in and what it will be exposed to.  Depending on material used, some of the benefits offered by solid polyurethane rubber include:

    • Popular for automotive, electrical, industrial, medical, marine and construction
    • Operating Temperature Range: -30°C to +80°C
    • Variety of grades, colours, hardnesses available
    • Energy (vibration/sound) absorption
    • Resistance to oils, grease, chemicals, solvents, ageing, tearing  and abrasion
    • Lightweight and flexible

    Advantages of using Solid Polyurethane Seals

    Solid Rubber Polyurethane Seals offer users a number of advantages .  These seals have the ability to be able to withstand a wide range of extreme temperatures, abrasion, moisture to name but a few.  It is also lightweight and shock absorbing, durable and flexible, maintaining its physical integrity under extreme heat and load bearing. 

    Solid PU seals have excellent oil-resistant qualities that are useful for exposure to oils or other lubricants.  The high temperature resistance makes Solid Polyurethane Seals popular for use along  production lines where there is extreme heat such as ovens and furnaces.  All of the above features also makes this material widely utilised within the automotive industry used as hoses, bearing pads, engine mounts, seals and gaskets. 

    Polyurethane can be utilised in a range of applications as it can be manufactured and converted in many ways, it be taken in roll or sheet form in full, these rolls and sheets can also be converted onsite here at Advanced Seals & Gaskets into a wide range of bespoke seals made to order, and for parts which can not be produced using sheets or are 3 dimensional or have a hollow centre, polyurethane can also be extruded and moulded in order to produce such parts. 

    Rubber Polyurethane Seals are generally known to last longer than rubber, especially in applications where it’s constantly stretched or otherwise exposed to stress, PU components are manufactured using a non-corrosive compound, available in in a choice of hardnesses and colours and due to the manufacturing techniques used in the production of the materials and parts, it is found utilised across a range of industries and applications.
