Sulphur Free EPDM Sponge Strip

Sulphur Free EPDM Sponge Rubber Strips

Sulphur Free EPDM Sponge Strip

Advanced Seals & Gaskets Ltd are one of the UK’s leading suppliers of cut strips (including sulphur free EPDM sponge rubber strips), which is one of the most popular products we manufacture and supply.

Ethylene Propylene Diene Monomer or EPDM is one of our most popular materials used for strip conversion, 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 and rolls using our state-of-the-art splitting machines, enabling us to manufacture cut strips starting from as little as just 1mm thick.

By following our customers samples, drawings or given dimensions, we can produce made-to-measure Sulphur Free EPDM sponge strips using our bandsaws, strippers, log cutters and even presses depending upon the size and quantity of strips required. In-house production allows us to closely oversee the whole production process to ensure that we consistently produce high-quality, competitive priced strips, which can be cut from sheets or rolls from 4mm in width and just up to 50 meters in length (depending on thickness). During the conversion process, we can laminate layers of Sulphur Free EPDM sponge material to produce greater depths, supplying them plain or laminated with a choice of self-adhesives and foils.

    What are Sulphur Free EPDM Sponge Rubber Strips?

    Sulphur Free EPDM sponge strips are lengths of material often cut to a specific length or supplied as continuous rolls (coils) to be cut as when they’re needed by the end user. EPDM sponge strips are often purchased to be used in the same way as a gasket, whereby they are used to create a seal between uneven surfaces and fill irregularities, cushioning or for anti vibration and acoustic insulations, sponge strips like these can sometimes be called foam tapes, sealing strips or gasket tape. Standard EPDM grades are manufactured and cured using sulphur, however for some delicate applications such as lighting, 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.

    Why Use Sulphur Free EPDM Sponge Strips?

    Sulphur Free EPDM sponge strips are manufactured using a closed cell material, offering thermal insulation, shock and vibration absorption. Sulphur Free EPDM Sponge strips 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 strips cut from this material are safe for use within lighting, electronics and automotive applications.

    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 Strips

    EPDM is a popular material, often chosen by customers 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 strips are safe for use within lighting, electronics and automotive applications as it will not react with metals or wires 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 can cut their own strips to, pre-manufactured finished components.
