Solid Rubber Polyurethane Seals
Solid Polyurethane (also known as urethane) is a versatile material widely used for seals in various industries. Its unique properties make it ideal for applications that require durability, flexibility, and abrasion resistance.
Polyurethane Seals
Advanced Seals & Gaskets Ltd is one of the UK’s leading converters and suppliers of Rubber Polyurethane Seals, working with worldwide materials, including Solid Polyurethane.
Solid Polyurethane is a synthetic polymer and a popular rubber used in a range of industries. It’s a high-performance rubber that's abrasion-resistant and highly durable. Standard industrial-grade Polyurethane rubber is usually available from stock in 60° and 80° shore hardnesses, in translucent and black colours; other hardnesses are available to order from 5 shore to 95 shore.
Due to our vast production capabilities, we can supply the highest-quality Polyurethane Seals in the form of gaskets, washers, O-rings, mouldings, and extrusions, all designed to prevent leaks or the ingress of air, fluids, and gases.
All our seals are made to order and are produced using samples or drawings provided by customers to ensure the final product fits the application perfectly. Advanced Seals & Gaskets Ltd specialises in creating custom seals tailored to unique customer requirements. As each seal type requires a different manufacturing process, ASG has invested heavily in various machinery, enabling us to offer high or low quantities at the most competitive prices.

What are Solid Polyurethane Seals?
A Solid Polyurethane Seal is a generic term for a product that frequently takes the form of cut gaskets, strips, washers, extruded or moulded profiles and edge trims.
Solid Polyurethane is a highly durable synthetic rubber material offering strength and abrasion resistance. Solid Polyurethane can be manufactured in roll or sheet form and can be taken in whole or converted by sawing, die cutting, and milling. Solid polyurethane can also be used to produce machined parts for specialised applications. Alternatively, for products which can’t be cut from a sheet or when a specific colour is requested, bespoke mouldings and extrusions are also available to order.
Why use Solid Polyurethane Seals?
Solid Rubber Polyurethane Seals can be used as a gap filler between surfaces, acting as a separator or barrier to prevent liquids, particles, or gases from 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 resistance, chemical, oil, grease, solvent, and hydrolysis resistance.
Solid Polyurethane Seals, compared to other rubber materials, have higher tear resistance, better high-load bearing capabilities, greater energy absorption for sound and vibration, and do 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 works with a vast network of material manufacturers and suppliers, giving our customers more choice when sourcing solid rubber. Our most popular grades include:
- Neoprene (CR) is one of our most popular solid rubber materials, available in various thicknesses. Neoprene is suitable for use where there is exposure to grease, oil, acids, ozone and even seawater.
- EPDM (Ethylene Propylene Diene Monomer), another very popular solid rubber, is excellent for 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 insulating material that can operate at both 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 harsh chemicals and high temperatures are present. Viton rubber offers resistance to fluids, oils, acids and petroleum-based liquids.
Polyether-based polyurethane is also available, offering enhanced resistance to water and hydrolysis.

Benefits of Using Solid Polyurethane
The type of solid rubber seal used will depend on the industry, environment, and application, as well as what it will be exposed to. Depending on the 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
- A variety of grades, colours, and hardnesses available
- Energy (vibration/sound) absorption
- Resistance to oils, grease, chemicals, solvents, ageing, tearing and abrasion
- Lightweight and flexible
- Excellent resilience, allowing the seal to recover its shape after deformation
Advantages of using Solid Polyurethane Seals
Solid Rubber Polyurethane Seals offer users several advantages. These seals can withstand a wide range of extreme temperatures, abrasion, and 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 rubber polyurethane seals are ideal for dynamic applications where movement and repeated loading occur.
Solid PU seals have excellent oil resistance, making them suitable for exposure to oils and other lubricants. The high-temperature resistance makes Solid Polyurethane Seals popular for use along production lines where extreme heat is present, such as ovens and furnaces. All of the above features also make 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 arethree3 dimensional or have a hollow centre, polyurethane can also be extruded and moulded 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.
