Sulphur Free EPDM Sponge Sheet

Sulphur Free EPDM Sponge Rubber Sheets

Sulphur Free EPDM Sponge Sheet

Ethylene Propylene Diene Monomer or EPDM is one of Advanced Seals & Gaskets more popular materials (used to manufacture materials and products such as sulphur free EPDM sponge rubber sheets), available in both solid and sponge variants in multiple grades, hardnesses and densities.

One such grade of EPDM we can offer is Sulphur Free EPDM Sponge or Peroxide Cured EPDM, which is manufactured and stocked in block form which can be split and converted into sheets using our state of the art splitting machines, enabling us to supply sheets starting from as little as just 1mm, in two meter by one meter in size as standard, or cut down into smaller bespoke sizes or pads. Our on-site laminating service not only allows us to laminate layers of sponge together to create greater depths or fabrications, but also enables us to supply them coated with a choice of self-adhesives, foils or even laminated to other materials.

    What Are Sulphur Free EPDM Sponge Rubber Sheets?

    Most EPDM sponge materials are manufactured as blocks and involve a ‘curing’ process in the production, standard EPDM grades are manufactured using sulphur, however for some delicate applications, a sulphur free or peroxide cured material is required as sulphur-cured sponges can corrode materials, such as copper, silver, and other metal components therefore inevitably causing electrical devices to fail. Sulphur Free EPDM has better chemical and temperature resistance and due to its sulphur free curing process, therefore components cut from these sheets are safe to use in applications including lighting and electronics.

    Why Use Sulphur Free EPDM Sponge Sheets?

    Sulphur Free EPDM is a closed cell material, offering thermal insulation, shock and vibration absorption. Sulphur Free EPDM Sponge sheets demonstrate good UV and Ozone resistance and excellent sealing properties against dust, air and moisture, they have a better chemical and temperature resistance compared to standard EPDM and so the components cut from these sheets are safe for use within lighting, electronics and automotive applications.

    Sulphur Free EPDM sponge sheets are a popular product as they give the customer the flexibility to be able to cut their own parts such as strips, gaskets or pads out as and when required or to cover larger surfaces reducing the need for joins in the material. By supplying the material in sheets, also gives customers the choice of taking smaller amounts of material, saving them money on not having to buy excessive quantities and having too much wasted material left over.

    The Benefits of Using Sulphur Free EPDM Sponge

    • Noise, vibration, shock and reduction
    • Naturally compressible to create the perfect air or moisture seal
    • Closed cell structure prevents bacteria and mould build up
    • Excellent properties making it popular for use in a range of industries and applications
    • Easy to convert into a range of products including pads, strips and gaskets, and will hold most adhesives well
    • Cost savings on equipment and appliance failure

    Grades Of EPDM Sponge Sheet Available

    EPDM sponge Medium density is air and water tight, ages well without becoming brittle, offers good UV resistance and is able to withstand a wide scale of temperatures ranging from -20°C up to a high of 85°C.  It’s excellent electrical insulation material, as well as having good resistance to ketones, ordinary diluted acids and alkalis, Ozone, UV and weathering as well as its general resistance to abrasion. EPDM foam is also flammability tested to meet FMVSS302 and UL94 HBF standards

    High Temperature EPDM Foam is closed cell and highly flexible even at low temperatures, with an amazing temperature range of -50°c to +128°c.  High-Temperature EPDM foam has many excellent mechanical characteristics including thermal and insulation properties, making this material ideal for many industries and applications including HVAC, Refrigeration, Pipeline, Automotive, White goods and Building & construction, etc.

    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 ingress of air, dust, moisture until compressed by 80% of their thickness, following this the product becomes water and air tight 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

    Advantages Of Using Sulphur Free EPDM Sheet

    Customers often choose EPDM for many of their projects as the material offers a number of advantages with certain grades adapted to meet particular applications. Sulphur Free EPDM sponge is a closed cell material, offering thermal insulation, shock and vibration absorption, good UV and Ozone resistance and excellent sealing properties against dust, air and moisture, but with an improved chemical and temperature resistance compared to standard EPDM.

    Materials cured or vulcanised using sulphur can react with metals such as copper or silver causing corrosion which leads to equipment failure. Sulphur free or peroxide cured EPDM sponge sheets are safe for use within lighting, electronics and automotive applications as it will not react with metals it comes into contact with. As Sulphur Free EPDM is manufactured in blocks, customers are able to order cut sheets, rolls of material so they cut their own sheets or bespoke components as the materials can be split or fabricated to order.
