Advanced Seals & Gaskets Ltd – Your Trusted UK Supplier of EPDM Sponge Materials
At Advanced Seals & Gaskets Ltd, we take pride in being one of the UK’s leading suppliers of premium sponge materials, including a comprehensive range of EPDM sponge options. We offer EPDM in multiple grades and densities, including medium, firm, high-temperature, semi-open cell, and EPDM/Neoprene blends, to suit various industrial and commercial applications.
Our standard EPDM sponge—excluding the high-temperature version—is stocked in block form, ready to be converted into sheets or bonded together to create continuous rolls in thicknesses starting from just 1mm. Thanks to our in-house conversion facilities, we can quickly split, cut, and prepare orders to your exact requirements. Whether you need rolls, sheets, strips, pads, gaskets, or washers, we can supply these in plain format or laminated with a wide choice of self-adhesive backings or foils for added performance and ease of installation.
What Is EPDM Sponge?
EPDM, short for Ethylene Propylene Diene Monomer, refers to the synthetic rubber compounds used to manufacture this versatile sponge material. Known for its excellent resistance to weather, ozone, and ageing, EPDM sponge is typically a closed-cell structure (except for our semi-open cell variant), making it ideal for both internal and external sealing applications.
Due to its durability and low compression set, EPDM sponge is widely used where a consistent and reliable seal is crucial. It performs well in harsh environments, offering long-lasting protection against moisture, air, and dust. The material is supplied in block form (excluding the high-temperature version) and can be converted into rolls, sheets, or custom parts such as strips, gaskets, washers, and pads.
We also offer extruded EPDM sponge profiles to suit more specialised applications.

Why use EPDM sponge?
EPDM sponge materials offer a number of excellent qualities and properties, often used to cut parts for use as seals to fill gaps and irregularities between two surfaces and to provide a solution to unwanted rattles, noise, vibrations, to seal against air, gas, dust and liquids, and can also be used to cushion between moving parts to reduce friction and damage to components and equipment.
EPDM sponge is a closed cell material, therefore even when not compressed(unless the semi open cell type is used), its nitrogen gas filled cells prevent the passage of air, liquids and gasses, the releasing of nitrogen gas gives the material its strong compression set and recovery characteristics. EPDM sponge materials are popular for use in a variety of applications and can be found used within the construction industry, in automotive interiors, electronic, lighting systems ventilation glazing seals and door sealing.
The Benefits of using EPDM sponge
• Noise, vibration, shock and abrasion reduction
• Flexible with good compression recovery
• Cost effective and readily available
• Naturally compressible to create the perfect seal to control air and water leaks
• Closed cell structure prevents bacteria and mould build up
• Excellent properties making it popular for use in a range of industries and applications
• Easy to convert into a range of products including pads, strips and gaskets, and will hold most adhesives well
Advantages of using EPDM sponge
EPDM sponge is a strong, synthetic material which is generally closed cell making it an ideal material for internal and external sealing applications where minimal compression is required for the material to work effectively, it has an excellent lifespan even when used outdoors and is free from dust and fibre.
EPDM sponge can be manufactured in a range of sizes and thickness, with a choice of foils and self adhesives applied to one or both faces. For very thick gaskets or a combination of properties are required, EPDM sponge can be laminated to other materials for use within more specialist applications.
EPDM sponge is a popular choice of material that is air and water tight, ages well without becoming brittle, offers good UV resistance and able to withstand a wide scale of temperatures ranging from -20°C up to a high of 85°C.
It’s excellent electrical insulation material, as well as having good resistance to ketones, ordinary diluted acids and alkalis, Ozone, UV and weathering as well as its general resistance to abrasion. EPDM foam is also flammability tested to meet FMVSS302 and UL94 HBF standards.
Grades of EPDM sponge rolls available
Acoustic foam gaskets hold various advantageous properties that are highly utilizable in a variety of industries.
The greatest advantage of using acoustic foam gaskets is the exceptional noise dampening capabilities of the material. As acoustic foam is an open cell material it is highly effective at absorbing sounds as well as cushioning and padding.
Acoustic foam gaskets commonly used as the material performs multiple functions at the same time, while the acoustic foam gasket is applied for cushioning the material will also absorb sound waves dampening the noise.

EPDM sponge Medium density is air and watertight, ages well without becoming brittle offers good UV resistance and is able to withstand a wide scale of temperatures ranging from -20°C up to a high of 85°C. It’s excellent electrical insulation material, as well as having good resistance to ketones, ordinary diluted acids and alkalis, Ozone, UV and weathering as well as its general resistance to abrasion. EPDM foam is also flammability tested to meet FMVSS302 and UL94 HBF standards.
High Temperature EPDM Foam is closed cell and highly flexible even at low temperatures, with an amazing temperature range of -50°c to +128°c. High-Temperature EPDM foam has many excellent mechanical characteristics including thermal and insulation properties, making this material ideal for many industries and applications including HVAC, Refrigeration, Pipeline, Automotive, White goods and Building & construction, etc.
Semi Open cell EPDM combines the flexibility of an open cell material with the excellent sealing capabilities of closed-cell types once compressed. Semi-open cell EPDM pads will allow for ingress of air, dust, moisture until compressed by 80% of their thickness, following this the product becomes water and airtight and behaves as a closed-cell product.
Firm Grade EPDM Foam is a more resilient material that will not compress as much as the standard grades under load, also this material benefits from increased tear strength and suits some of the more demanding applications such as Automotive, White Goods, Marine, Defence, Building and Construction, etc
