neoprene/EPDM Sponge Sheets

Neoprene / EPDM Sponge Sheet

Here at Advanced Seals & Gaskets, we offer a vast catalogue of sheet materials, including neoprene/EPDM blend sponges. Our neoprene/EPDM sponge sheets are converted from blocks using our state of the art splitting machines, meaning we can supply sponge sheets in thicknesses starting from as little as just 1mm, in two meters by one meter in size as standard. 

Our onsite laminating service not only allows us to laminate layers of sponge to create greater depths but also enables us to supply them coated with a choice of self-adhesives, foils or even layers of other materials.  Neoprene/EPDM sponge sheets are popular as they give the customers and end-users the flexibility to be able to cut their own parts such as strips, gaskets or washers out as when they are required.

What are Neoprene/EPDM Sponge Sheets?

Neoprene/EPDM sponge is just one of many closed-cell materials on offer from our vast catalogue which we can use to cut pads.  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.

Neoprene/EPDM sponge is one of ASG’s core stock materials, held in the block, neoprene/EPDM sponge sheets and roll form in a range of thicknesses starting from as little as 1mm ensuring sheets can be despatched within a minimum timeframe. 

Rolls are sometimes preferred by customers as they have the freedom to cut their own neoprene/EPDM sponge sheets in various sizes as and when they are required, which can also be manufactured with a choice of finishes including foils and self-adhesives.

    Why use Neoprene/EPDM Sponge Sheets?

    Our neoprene/EPDM sponge sheets offer 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 sponge sheets have 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 sheets and products cut from them are suitable for most internal and external applications for example heating & ventilation, white goods, automotive, electrical, sealing, etc

    The Advantages of Using Neoprene/EPDM Sponge Sheets

    There are many advantages to using neoprene/EPDM sponge sheets 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 sponge sheets have a wide operating temperature range and display mechanical and chemical properties of both materials making them 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 at any desired thickness starting from just 1mm, or laminate layers of material to create a greater depth or composite materials where required. 

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

    Benefits of using Neoprene/EPDM Sponge

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

    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 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.
