Polyurethane Rubber Gaskets

Polyurethane Rubber Gaskets

Cut gaskets are one of  Advanced Seals & Gaskets Ltd most popular products, converted on-site using a diverse range of materials including many foams, sponges, plastics and rubbers.  Polyurethane Rubber Gaskets are just one group used in our production, available in foam and solid versions. 

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, and in thicknesses up to 100mm (depending on sheet size) from which gaskets can be cut.  

Using this high quality material and state of the art machinery, our in-house conversion facilities can manufacture bespoke items to match our customers samples or drawings, using one of our many presses or CNC (oscillating knife) machines.   From a simple rectangular picture frame gasket, to a more complex shape with cut-outs, notches or bolt holes, whether it’s a small sample batch or multi-thousand run, we have a machine designed to quickly and accurately produce perfectly formed gaskets everytime.

    What are Polyurethane Rubber Gaskets?

    Solid Polyurethane Rubber Gaskets can be cut and supplied in the form of a strip or pad, but are generally an intricately cut shaped piece of material placed between two surfaces to create a low pressure seal preventing the leakage of liquids or gas and to seal against the intrusion of dust and debris. 

    Polyurethane Rubber Gaskets are made from an extremely durable synthetic rubber material offering strength and abrasion resistance.  Solid Polyurethane can be manufactured in roll or sheet form  from which gaskets can be cut using one of our many presses or CNC machines, for very bespoke gaskets a moulded option may also be available. 

    PU gaskets can be placed between two surfaces creating a level surface to act as a spacer,  they are also used within equipment and machinery between moving parts for vibration dampening, sealing and noise reduction.

    Why use Solid Polyurethane Rubber Gaskets?

    Solid Polyurethane Rubber Gaskets offer strength and durability alongside other properties including good ageing, chemical, oil, grease  and solvent resistance.   Solid Polyurethane gaskets in comparison to other rubber materials, have a higher tear resistance, better high load bearing capabilities, energy absorption - sound and vibration and do not discolour as easily. 

    Solid Polyurethane gaskets offer a working temperature range of -30°C to +80°C, are available in thicknesses up to 100m and can be made in a wide range of colours and  hardnesses from 5 to 95 shore.   Solid Polyurethane gaskets are often used within electrical appliances, engineering applications, anti-vibration and automotive engineering and construction to name 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 Polyurethane Rubber Gasket 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 Gaskets

    Solid Polyurethane Rubber Gaskets offer users advantages which include its ability to withstand a wide range of extreme temperatures, abrasion and moisture.  Solid PU gaskets are lightweight, shock absorbing, durable and flexible, maintaining its physical integrity under extreme heat and load bearing.  Solid PU gaskets have excellent oil-resistant qualities that are useful for exposure to oils, grease or other lubricants. 

    The high temperature resistance makes Solid Polyurethane gaskets popular for use within  production lines where there is extreme heat such as ovens and furnaces.  All of the above features also make gaskets cut from this material widely utilised within the automotive industry used as engine mounts and seals.  Polyurethane gaskets can be cut from sheets or rolls of material, but for very thick or bespoke washers they can be extruded or moulded in order to produce such parts. 

    Polyurethane rubber is generally knows 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 range of manufacturing techniques used in the production of the materials and parts, it is found utilised across a range of industries and applications.
