High Temperature EPDM Sponge Washers
High Temperature EPDM Sponge Washers
Advanced Seals & Gaskets Ltd work with a wide network of material manufacturers, enabling us to offer a range of EPDM sponge, 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. Our high-temperature EPDM sponge is manufactured at continuous lengths in various standard thicknesses with a skin finish on both faces from which high-temperature EPDM sponge rubber washers can be cut.
Our in-house conversion facilities use high-temperature EPDM sponges to manufacture a range of high-temperature EPDM sponge rubber washers that are all made to order and produced using samples or drawings to ensure the final product perfectly fits the application - even offering a small sample run if required.
Depending on the size and quantity of the high-temperature EPDM sponge rubber washers required, our production team will select from our range of atoms, autos, travelling head, kiss cut pressing machines or for very large or thick washers, we can programme our CNC (oscillating knife) to produce the washers in the most efficient way to keep lead times down.
What are High Temperature EPDM Sponge Rubber Washers?
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.
Washers are a flat ring (comprising of an outer diameter (OD), internal diameter (ID) and the thickness) cut from a sheet or roll of material, which is placed between two surfaces creating a level surface, acting as a spacer or between a nut/bolt to spread the pressure when tightened. High-temperature EPDM sponge rubber washers are also used in a number of vibration dampening, sealing and insulating applications.

Why use High Temperature EPDM Sponge Rubber Washers?
High-temperature EPDM sponge rubber washers are suitable for applications that require ozone, UV and weathering resistance, combined with the ability to withstand high temperatures. High-Temperature EPDM sponge washers 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 products (such as high-temperature EPDM sponge rubber washers) 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
- High-temperature EPDM sponge rubber washers has excellent insulation properties
- can be manufactured in either plain or self-adhesive backed
- preventing condensation and corrosion
- High-temperature EPDM sponge rubber washers has a closed-cell structure prevents bacteria and moulds build-up
The Advantages of using High Temperature EPDM Sponge Rubber Washers
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 which are used for the production of washers. 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, high-temperature EPDM sponge rubber washers have many excellent mechanical characteristics including thermal and insulation properties. High-temperature EPDM sponge rubber washers offer 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 make 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 washers 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
