High Temperature EPDM Sponge Pads

Advanced Seals & Gaskets Ltd pride itself on being able to work with a multitude of reputable material manufacturers and suppliers, enabling us to offer pads cut using a range of high-quality 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.     

Our High-Temperature EPDM sponge is manufactured at continuous lengths in various standard thicknesses with a skin finish on both faces from which pads can be cut.  Our High-Temperature EPDM Sponge pads are produced on-site using drawings or measurements provided by our customers, with whom we work closely to ensure the final product is to their exact specification. 

Depending upon the size and quantity of pads required, one of many presses, bandsaws or CNC machines can be used to manufacture the final product, from one-off samples to multiple batches runs, which can be supplied as loosely cut parts, or kiss-cut on rolls where a high quantity is required or for use on fast-paced assembly lines. 

Our High-Temperature EPDM Sponge pads can be supplied in a plain finish, laminated in layers to create greater thicknesses,  laminated to other materials or coated with a choice of self-adhesives and foils prior to the pads being cut.

What are High Temperature EPDM Sponge Rubber Pads?

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.   

The closed-cell structure of High-Temperature EPDM Sponge means it can be used in sealing applications against dust, moisture and air therefore a great choice for the production of pads.  High-Temperature EPDM sponge pads are cut from rolls or sheets of material and are often utilised in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities. 

Our High-Temperature EPDM Sponge pads can be produced as squares or rectangles with the option of radius corners, and also as circular or oval-shaped pads or ‘discs’,  in a range of thicknesses.  Manufacturing pads in-house even means we can supply them in a plain or self-adhesive backed finish and even laminate multiple types of material together to create bespoke and unique variations.

    Why use High Temperature EPDM Sponge Rubber Pads?

    High-Temperature EPDM sponge pads are suitable for applications that require ozone, UV and weathering resistance, combined with the ability to withstand high temperatures.   

    High-Temperature EPDM sponge pads 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 pads 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
    • can be manufactured in either plain or self-adhesive backed
    • preventing condensation and corrosion
    • Closed-cell structure prevents bacteria and mould build-up

    The Advantages of using High Temperature EPDM sponge rubber Pads

    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 is used for cutting pads.   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 pads have many excellent mechanical characteristics including thermal and insulation properties. High-Temperature EPDM sponge pads 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 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 pads 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
