High Temperature EPDM Sponge Rubber
Advanced Seals & Gaskets Ltd supply a range of EPDM sponge materials, in various densities, grades and in various different products cut from the material. One of the EPDM sponge grades we can offer is a high temperature EPDM sponge rubber.
Our high temperature EPDM sponge rubber is manufactured at continuous lengths in various standard thicknesses with a skin finish on both faces, however, bespoke thicknesses may also be supplied as we can run the rolls through our state of the art splitting machines.
On-site conversion facilities mean we can stock and supply rolls in thicknesses starting from as little as just 1.5mm or convert them into multiple usable finished parts including pads, washers, gaskets or strips - all supplied plain or laminated with a choice of one of our many self-adhesives or foils.
What is High Temperature EPDM Sponge Rubber?
EPDM is an abbreviation of Ethylene Propylene Diene Monomer which are the chemical components used to manufacture this sponge, this HIgh-Temperature variant is a very flexible, closed-cell elastomeric (rubber-like properties of a polymer) insulation material, which has many of the properties of a standard EPDM sponge, but formulated to withstand higher temperature applications.

What are Acoustic Foam Gaskets?
Gaskets are a ring, sheet or cut shape substance or material used to act as a seal between surfaces. The purposes for gaskets of this type are to prevent leakages of liquid or gas, keep joints air-tight and prevent the intrusion of damaging debris such as dust.
Acoustic foam is an open cell, lightweight, class O fire rated polyurethane material that is primarily used in soundproofing applications such as recording studios, and It is a non-fibrous foam meaning the gaskets can be used within airflow systems as the material doesn’t shred, dust or migrate when exposed to high velocity airflow.
Acoustic Foam is resistant to most fungus, mildew and bacteria growth as it contains anti-fungal agents which makes it a popular choice for use within the air conditioning and duct-work systems.
Why use High Temperature EPDM Sponge Rubber?
High temperature EPDM sponge rubber is suitable for applications that require ozone, UV and weathering resistance, combined with the ability to withstand high temperatures.
High-Temperature EPDM can operate between a temperature range of -50°c to +150°c, remaining flexible and still providing an adequate seal at very high or low temperatures.
High temperature EPDM sponge rubber products are non-porous, non-fibrous, resists mould and fungus growth and is highly moisture resistant, preventing condensation and corrosion.
The Benefits of Using High Temperature EPDM Sponge Rubber
- Temperature range of -50°c to +150°c
- Excellent ozone, weathering and UV light resistance
- Excellent thermal conductivity
- Excellent insulation properties
- High temperature EPDM sponge rubber can be manufactured in either plain or self-adhesive backed
- Preventing condensation and corrosion
- Closed-cell structure prevents bacteria and moulds build up
The Advantages of Using High Temperature EPDM Sponge Rubber
High-Temperature EPDM material can be supplied in thicknesses between 6mm and 32mm and manufactured in roll format 1 metre wide a skin finish on one or both sides dependent upon thickness required. As we carry out our conversion onsite, we can split or laminate these materials to create thinner or greater non-standard thicknesses to order.
As well as the temperature range, the high temperature EPDM sponge rubber has many excellent mechanical characteristics including thermal and insulation properties. High temperature EPDM sponge rubber offers moisture-resistant properties which prevent condensation, corrosion and the growth of bacteria, rot and fungus.
This material has some resistance to many chemicals, solvents, grease and saltwater, combined with a temperature resistance of 150°C makes it ideal for many demanding applications and industries including HVAC, Refrigeration, Pipeline, Automotive, Solar panels, Steam, White goods and Building & construction, etc.
Grades of EPDM Sponge 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:
Medium Density EPDM is available in black or white colour options. EPDM sponge is a strong, synthetic material that has a closed-cell structure making it an ideal material for internal and external sealing applications where minimal compression is required for the material to work as an effective seal. 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 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
