High Temperature EPDM Sponge Sheet

Advanced Seals & Gaskets Ltd supply a range of EPDM sponge sheets in various densities, grades and in various different products cut from the material.  One of the EPDM sponge grades we can offer is High-Temperature EPDM sponge, which is manufactured at continuous lengths in various standard thicknesses from 3mm to 32mm with a skin finish on both faces, however, we can cut these rolls down and supply them in sheets of 1 meter by 1 meter or 2 meters by 1 meter in size. 

These sheets can also be supplied in bespoke thicknesses as we can run them through our state of the art splitting machines or laminate layers together to achieve greater thicknesses.  On-site conversion facilities mean we can stock and supply High-Temperature EPDM Sponge sheets 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 are High Temperature EPDM Sponge Rubber Sheets?

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.  

High-Temperature EPDM sponge sheets are cut from rolls and often taken in 1 meter by 1 meter or 2 meter by 1-meter sizes, which are easy to transport and gives the customer and end-user the flexibility to be able to cut their own strips, gaskets, washers, etc out as and when they are required as opposed to taking bulk quantities of the same product.

    Why use High Temperature EPDM Sponge Rubber Sheets?

    High-Temperature EPDM sponge sheets of material are suitable for applications that require ozone, UV and weathering resistance, combined with the ability to withstand high temperatures.  High-Temperature EPDM sponge sheets 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 is non-porous, non-fibrous, resists mould and fungus growth and is highly moisture resistant, preventing condensation and corrosion.   High-Temperature EPDM Sponge sheets and products cut from them are popular 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 seals.

    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
    • can be manufactured in either plain or self-adhesive backed
    • preventing condensation and corrosion
    • A closed-cell structure prevents bacteria and moulds build-up

    The Advantages of using High Temperature EPDM Sponge Rubber Sheets

    High-Temperature EPDM sponge sheets can be supplied in thicknesses between 3mm and 32mm and manufactured in roll format 1 metre wide a skin finish on one or both sides dependent upon thickness required which can be cut down into sheets.  As we carry out our conversion onsite, we can split or laminate these sheets of material to create thinner or greater non-standard thicknesses to order. 

    As well as the temperature range, the High-Temperature EPDM sponge has many excellent mechanical characteristics including thermal and insulation properties. High-Temperature EPDM sponge 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 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  rolls, 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
