Sulphur Free EPDM Seals
Seals and sealing components are supplied by ASG using materials from worldwide high-quality suppliers. Ethylene Propylene Diene Monomer or EPDM is one of Advanced Seals & Gaskets' more popular materials (used within our sulphur free EPDM sponge rubber seals), available in both solid and sponge variants in multiple grades, hardnesses and densities.
One such product we can offer is Sulphur Free EPDM Sponge or Peroxide Cured EPDM seals, taking the form of gaskets, washers, cord and extrusions, which are all designed for the purpose of preventing leaks or the ingress of air, fluids and gas.
All our Sulphur Free EPDM sponge seals are made to order and are produced by following samples or drawings provided by customers to ensure the final product perfectly fits the application. As each form of EPDM sponge seal needs to be manufactured using a different process, ASG have invested heavily in various machinery allowing us to offer seals in both high and low volumes at competitive prices.

What Are Sulphur Free EPDM Sponge Rubber Seals?
Sulphur Free EPDM sponge seals are a device that is used to join surfaces together, acting as a separator or a barrier to prevent liquids, particles or gases escaping or penetrating the application. ‘Seal’ is a generic term for products often taking the form of cut gaskets, strips, washers, extruded or moulded profiles , edge trims and cord.
Most EPDM sponge materials are manufactured using sulphur, however for some delicate applications such as lighting or electronics, 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 Seals?
Closed cell foams and sponges are often used for the production of seals and sealing devices.
Sulphur Free EPDM is one of these materials, offering thermal insulation, shock and vibration absorption. Sulphur Free EPDM Sponge seals 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 seals are safe for use within lighting, electronics and automotive applications.
Sulphur Free EPDM sponge can be supplied to customers as pre-manufactured seals, or supplied in rolls and sheets, with a plain or self adhesive finish, to give customer the flexibility to be able to cut their own seals as when required or to seal and cover larger surfaces reducing the need for joins in the material.
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 Seal 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 Seals
Customers and end users often choose EPDM for many of their sealing needs and projects as the material offers a number of advantages with certain grades adapted to handle 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 seals are safe for use within lighting, electronics and automotive applications as it will not react with metals such as the surfaces or wires it comes into contact with.
As Sulphur Free EPDM is manufactured in blocks, customers are able to order full sheets, rolls of material so they cut their own seals, or they can take bespoke components as the material can be fabricated to order.
