EPDM Foam Sheet
EPDM Foam Sheet
Here at Advanced Seals & Gaskets Ltd, we offer a vast catalogue of sheet materials, including EPDM medium density sponges. Our EPDM sponge sheets are converted from blocks using state of the art splitting machines, meaning we can supply sheets starting from as little as just 1mm, in two meters by one meter in size as standard, or cut down to bespoke sizes and pads.
Our on-site laminating service not only allows us to laminate layers of sponge together to create greater depths but also enables us to supply them coated with a choice of self-adhesives, foils or even laminated to other materials.
EPDM sponge sheets are a popular product as they give the customer the flexibility to be able to cut their own parts such as strips, gaskets or pads out as and when required or to cover larger surfaces reducing the need for joins in the material.
What are EPDM Sponge Sheets?
EPDM sponge is just one of many closed cell sponge materials from our vast catalogue, EPDM is an abbreviation of Ethylene Propylene Diene Monomer which are the chemical components used to manufacture this sponge.
EPDM sponge is a strong, synthetic material that is closed cell making it an ideal material for internal and external sealing applications where minimal compression is required for the material to work effectively. EPDM sponge is one of ASG’s core stock materials, held in a block, sheet and roll form in a range of thicknesses starting from as little as 1mm ensuring sheets can be despatched within a minimum timeframe.
Rolls are sometimes also taken by customers as they have the freedom to cut their own sheets in various sizes as and when they are required, which can also be manufactured with a choice of finishes including foils and self-adhesives.

Why Use EPDM Foam Sheets?
EPDM sponge sheets and products cut from them are often used 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.
In order for a material to work effectively, it needs to compress and fill the entire space to create pressure and an airtight protective seal. As EPDM sponge is a closed-cell material, even when not compressed, 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 sheets are a popular product in a variety of applications for a number of reasons and can be found used within the construction industry, in automotive interiors, electronic, lighting systems ventilation glazing seals and door seals.
The Benefits of using EPDM Sponge Sheets
- 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 moulds 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 gaskets, and will hold most adhesives well
The Advantages of Using EPDM Sponge Sheets
EPDM sponge is a strong, synthetic material that is 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 sheets can be manufactured in a range of sizes and thicknesses, laminated with a choice of foils and self-adhesives applied to one or both faces. For very thick sheets or where a combination of properties is required, EPDM sponge sheets can be laminated together in layers or can be laminated to other materials for use within more specialist applications.
EPDM sponge is a popular choice of material that 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.
Grades of EPDM Sponge Sheets Available
ASG stock a variety of other grades and densities of EPDM sponge which can call be used to manufacture gaskets each suited to individual applications. These include firm grade, high temperature and semi-open cell varieties:
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 the 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
