What are High Temperature EPDM sponge rubber Seals?
EPDM is an abbreviation of Ethylene Propylene Diene Monomer, which is the chemical component used to manufacture this sponge. This high-temperature variant is a very flexible, closed-cell elastomeric (rubber-like properties of a polymer) insulation material that has many of the properties of a standard EPDM sponge but is formulated to withstand higher-temperature applications. It also offers good resistance to harsh environmental conditions, chemical exposure, and dimensional compression, making it highly durable and reliable in demanding applications.
High temperature EPDM sponge rubber seals are a device or substrate that are used to securely join surfaces together, to either act as a separator or a body to prevent liquids, solids or gases from escaping or penetrating the application, they can take the form of cut gaskets, strips, washers, extruded profiles and cord, all manufactured using the same material which can be compressed, which in turn further ‘hardens’ the material to create a secure seal. These seals are known for their excellent weather resistance and ozone resistance, making them ideal for outdoor and exposed applications. In addition to sealing and cushioning, the material effectively absorbs vibration, reducing noise and mechanical impact in industrial and automotive settings.
Many of our high-temperature EPDM sponge rubber seals can be supplied with a choice of self-adhesives to assist with placement and holding the seal in position.n

Characteristics of Closed-Cell Sponge
Closed-cell sponge rubber, particularly EPDM sponge rubber, is renowned for its exceptional performance in demanding sealing applications. The closed-cell structure of this material is engineered to prevent the passage of air and water, resulting in a watertight, airtight seal that is crucial for outdoor sealing applications and environments exposed to moisture or dust. This unique structure also enables EPDM sponge rubber to withstand high temperatures and extreme temperature fluctuations, making it a reliable choice for high-temperature environments.
Manufactured from ethylene-propylene-diene monomer (EPDM), closed-cell sponge rubber offers outstanding resistance to ozone, UV light, and weathering. This ensures long-term durability and consistent sealing performance, even under harsh outdoor conditions. The material’s excellent chemical resistance further enhances its suitability for applications where contact with oils, solvents, or other chemicals is likely.
In addition to its resistance to environmental factors, closed-cell sponge rubber offers superior insulation. This makes it an ideal material for applications requiring thermal insulation, such as HVAC systems, automotive door seals, and construction gaskets. The material is available in a variety of densities and standard thicknesses, typically ranging from 1mm to 30mm, allowing for customisation to meet the specific requirements of each sealing application. Bespoke gaskets and seals can also be manufactured to precise dimensions, ensuring a perfect fit and optimal performance.
The closed-cell structure not only delivers excellent resistance to moisture and dust but also protects against the ingress of contaminants, making EPDM sponge rubber a preferred choice for door, automotive, and construction seals. For added convenience and secure installation, closed-cell sponge rubber can be supplied with an adhesive backing, streamlining the application process and ensuring a reliable seal.
Overall, the combination of a closed-cell structure, high temperature resistance, and excellent durability makes EPDM sponge rubber an ideal material for a wide range of sealing applications. Whether used in outdoor applications, automotive manufacturing, or construction, this material consistently delivers protection, insulation, and long-lasting performance in even the most challenging environments.
Why use High Temperature EPDM Sponge Rubber Seals?
High-temperature EPDM sponge rubber seals are ideal for customers seeking both standard and non-standard profiles to fit specific applications. The process of producing an extruded seal ensures the customer receives a product each time, which is essential for high-volume production and assembly. These seals are also highly suitable for a wide range of industrial applications due to their durability, chemical resistance, and ability to withstand extreme temperatures, making them a preferred choice across sectors such as chemical processing, manufacturing, and the automotive industry.
By using high-temperature EPDM sponge rubber seals, end users benefit from a perfectly fitting rubber profile suitable for applications that require ozone, UV, and weathering resistance, combined with the ability to withstand high temperatures.

Grades of EPDM Sponge Available
ASG stocks a variety of EPDM sponge grades and densities, suitable for manufacturing seals, each suited to individual applications. These include firm grade, high temperature and semi-open cell varieties:
Medium-density EPDM is available in black or white. EPDM sponge is a strong, synthetic material with a closed-cell structure, making it ideal for internal and external sealing applications where minimal compression is required for effective sealing. Medium-density EPDM sponge has a density of 90 – 140kg/m3, an operating temperature range of -20°c to +85°c and is flammability tested to FMVSS 302. Semi-open-cell EPDM combines the flexibility of an open-cell material with the excellent sealing capabilities of a closed-cell material once compressed. Semi-open cell EPDM pads allow for the ingress of air, dust, and moisture until compressed to 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, and Building and Construction.
