Polyurethane Foam Seals
As one of the UK’s largest non-metallic material converters, Advanced Seals & Gaskets Ltd has a network of manufacturers and suppliers enabling us to offer an array of seals, including those produced using various grades of polyurethane foam. We supply the highest quality polyurethane foam 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 has invested heavily in various machinery meaning we can offer high or low quantities.
What are Polyurethane Foam Seals?
Polyurethane foam is one of the members of the polymer family, it is a low-density foam from which many products can be manufactured including various seals. ‘Seal’ is a generic term for products often taking the form of cut gaskets, strips, washers, extruded or moulded profiles and edge trims. They are often used as a gap-filler between surfaces, acting as a separator or a barrier to prevent liquids, particles or gases from escaping or penetrating the application and in a number of vibration dampening, sealing and insulating applications.
Why use Polyurethane Foam Seals?
Polyurethane foam seals are available in a range of colours, thicknesses and densities, all of which suitable for acoustic and thermal conductive applications. Polyurethane foam offers good sealing properties against air and dust and is resistant to UV and ozone. Polyurethane seals can also be produced using specialist grades which include conductive, static dissipative and flame-retardant.
Available Grades
Advanced Seals & Gaskets can offer customers a huge choice when they come to us for their washers, ensuring we can offer a solution to just about any application. Each type of polyurethane has its own range of properties, colours, thicknesses, etc – our most popular include:
- Acoustic
- egg box
- HLB
- Basotech
- Polyester

Benefits of Using Polyurethane Foam Seals
Polyurethane foams are available in a wide variety, allowing us to manufacture seals for use within various applications and industries. Polyurethane foam performs well across a wide temperature range, has resistance to compression and chemicals, offers good vibration and impact absorption and can be manufactured with extra additives to create specialist grades which include conductive, static dissipative and flame-retardant. Some of the popular uses for polyurethane seals include heating & ventilation, automotive, dust sealing and building & construction applications.
