Polyurethane Rubber Mouldings
Some applications require a very bespoke seal or gasket, for example is a very awkwardly shaped space or product which requires sealing or covering. Advanced Seals & Gaskets Ltd work with a network of material suppliers and manufacturers enabling us to supply such products, available in a vast range of simple to very complex rubber Polyurethane rubber mouldings.
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.
A Polyurethane rubber moulding requires specialist machinery for the process (compression, transfer or injection moulding) as they are generally bespoke shapes, with complex profiles, have a ribbed finish or may require a lip or curved edge - for these reasons solid PU mouldings can not simply be pressed from sheet material.
All our polyurethane rubber mouldings are made to order and are produced by following samples or CAD drawings provided by customers, from which a tool or moulded cavity is made. Polyurethane rubber mouldings can take many forms for example feet, buffers, sleeves and o-rings to name a few, all designed to provide protection, prevent the leakage or ingress of air, fluid or gas and to be aesthetically pleasing.

What are Solid Polyurethane Rubber Mouldings?
Solid Polyurethane is an extremely durable synthetic rubber material offering strength and abrasion resistance. Solid Polyurethane rubber mouldings are usually manufactured in 60° shore and 80° shore hardnesses and in translucent and black colour options, with other hardnesses available to order range from 5 shore to 95 shore. ‘Moulding’ is the procedure by which raw material, in this case solid polyurethane rubber is turned into a specific shape and usable product using 1 of 3 processes:
- INJECTION MOULDING - the process by which raw/uncured material heated until moulton and then fed through a nozzle into a mould. Pressure and heat levels are adjusted within the cavity causing the material to ‘cure’ and the moulded product is formed.
- COMPRESSION MOULDING consists of a top and bottom pre-heated steel mould/cavity into which raw material is poured in and the two halves are closed together. This tool is heated and the material melted creating the desired shape and the final product. Although this process is great for bespoke moulding, it can be very time consuming for high volume production.
- TRANSFER MOULDING is a more complex process, where raw/uncured material is loaded into the transfer pot and heated, a plunger slowly enters the pot building pressure, forcing the melted rubber through the sprue or channel leading to the mould/cavity. Once the mould is filled, the raw material forms the desired shape and is cured before the moulding is removed.
Why use Solid Polyurethane Rubber Mouldings?
Along with the strength and durability offered by Polyurethane rubber mouldings, other properties include good ageing, chemical, oil, grease and solvent resistance. Solid Polyurethane in comparison to other rubber materials, has 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, and can be moulded in a wide range of hardnesses from 5 to 95 shore, colours and shapes.
Polyurethane rubber mouldings are ideal for customers who are looking for a non-standard profile to fit specific applications, the process of producing a moulded part means the customer is guaranteed to have an identical product each time, which is essential for high volume production and assembly.
Polyurethane rubber mouldings can be made in a ‘solid’ shape such as cord, or ‘hollow’ where the moulding is empty and produced with just an outer wall. The types of mouldings available are endless as they can be used in practically every industry, some examples of mouldings include rubber sleeves, rubber bellows (coverings), rubber feet, buffers, remote and console buttons 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 rubber 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 Mouldings
Polyurethane rubber mouldings offer users a number of advantages, the material 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 PU has excellent oil-resistant qualities that are useful for exposure to oils or other lubricants. The high temperature resistance makes Solid Polyurethane mouldings popular for use in applications where there is extreme heat such as ovens and furnaces. All of the above features also make Solid PU moulded parts widely utilised within the automotive industry used as hoses, bearing pads, engine mounts, seals and gaskets.
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 manufacturing techniques used in the production of the materials and parts, it is found utilised across a range of industries and applications.
