Neoprene / EPDM Blend Sponge Rubber

Advanced Seals & Gaskets Ltd stock and supply materials supplied from leading manufacturers located across the world, including many types of sponge rubber.  One of our most popular materials is Neoprene EPDM Blend sponge, which is produced in 2-meter x 1 meter-sized block or ‘bun’ form, these are held by ASG read to be converted into a range of products, manufactured in-house using our state of the art machinery and highly skilled workforce. 

Blocks of Neoprene/EPDM Blend sponge can be split down into sheets in any thickness starting from as little as 1.5mm, or these blocks can be joined together and split into continuous lengths or rolls of material up to 100 meters long depending on thicknesses. 

Neoprene/EPDM Blend sponge can be taken in full sheet or roll form or alternatively further converted into a range of finished products including washers, strips, pads or gaskets, all of which can be supplied in a plain finish or coated with a choice of one of many self-adhesives or foils. 

What is Neoprene/EPDM blend sponge?

Neoprene/EPDM  sponge is just one of many closed-cell materials on offer from our vast catalogue, manufactured from a blend of high-quality chemicals known as Polychloroprene (Neoprene) and Ethylene Propylene Diene Monomer (EPDM), this combination of the two materials creates a highly versatile product, suitable for applications where a stable, flexible and durable material is required.  This co-polymer of EPDM and Neoprene offers users all the benefits of EPDM with the added oil resistance of Neoprene.

    Why use Neoprene/EPDM sponge?

    Our Neoprene/EPDM blend sponge offers a number of excellent qualities and properties including resistance to UV light, ozone exposure and weathering, it is closed cell and non-porous making it air and water-resistant, has excellent ageing properties, good resistance to acid and some resistance to oil.

    Neoprene/EPDM blend has a wide working temperature range of -40º to + 85º and has flame retardant properties conforming to classification UL94 HF1. 

    This combination of properties means Neoprene/EPDM sponge and products cut from them are suitable for most internal and external applications for example heating & ventilation, white goods, automotive, electrical, sealing, etc

    Benefits of using Neoprene/EPDM Sponge

    • Closed-cell material which prevents bacteria/mould growth
    • Air & watertight
    • Good weathering, UV & Ozone resistance
    • EPDM blend sponge has vibration absorption properties
    • High tensile strength & withstand heavyweight
    • EPDM blend sponge is durable and easy to convert

    What are the advantages of using Neoprene/EPDM sponge?

    There are many advantages to using neoprene/EPDM sponge in your project, not only does the material have excellent sealing capabilities under compression, its closed cell structure prevents the growth of bacteria and mould, it offers properties such as noise and vibration insulation, UV resistance and good recovery properties, as well as easily holding a number of self-adhesives, foils and other coverings. 

    Neoprene/EPDM blend sponge has a wide operating temperature range and displays mechanical and chemical properties of both materials making it a robust and flexible material that will resist deterioration over time. 

    As this material is stocked in block form, we can split the material down into sheets or continuous rolls at any desired thickness starting from just 1.5mm, laminated layers of material to create a greater depth or laminated to other materials to create composites where required.   

    Neoprene/EPDM blend sponge is easy to convert into other finished parts using a range of machines including bandsaws, presses, oscillating knives, log cutters and kiss-cut presses.

    Different grades of Neoprene Available

    Advanced Seals & Gaskets work closely with a number of high-quality material manufacturers and stock a number of grades of neoprene sponge alongside the blended variety, giving our customers more choice, these neoprene variations include medium density, firm and flame retardant grades.

    Medium Density Neoprene sponge has a closed-cell structure creating an air, dust and watertight seal, it has excellent ageing properties, being resilient to ozone, sunlight, oxidation and UV exposure and not becoming brittle over time.  Neoprene sponge gaskets are resistant to oil, chemically inert, flame retardant and have a wide working temperature range of -40°C to +115°C

    Firm Grade Neoprene sponge gaskets are fire resistance tested to FMVSS 302, and have a density of 180kg (+/- 25), meaning they can be used in more heavy-duty applications, where less compression is needed to create a tight seal.  

    Flame Retardant Neoprene gaskets are grey in colour, can handle continuous temperatures from -40°C to 115°C and are subject to more vigorous fire testing (FMVSS 302, UL94, AFNOR P9750), this makes the material ideal for use within construction and transport applications where a flame-resistant barrier may be required.
