Neoprene/EPDM Sponge Gaskets

As leading converters of sponge and rubber products, ASG is able to offer the best quality and service in neoprene/EPDM sponge gaskets. As neoprene/EPDM is one of our core stock materials, gaskets can be turnaround within a minimal lead time using sheets or rolls split directly from the block.

All our neoprene/EPDM sponge gaskets are cut in house using state of the art machinery and are produced using drawings provided by our customers, giving us the ability to work with them closely and ensure the final product is to their exact specification.

Depending upon the size and quantity of gaskets required, we have a machine that can manufacture the final product, from one-off samples to multiple batches runs, our expertly trained staff can manufacture gaskets in thicknesses ranging from as little as 1mm thick, and in plain or self-adhesive backed finish using one of our many presses, kiss-cut machines or CNC oscillating knife.

Gaskets are one of our more popular products as many industries require them for sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration.

What are Neoprene/EPDM Sponge Gaskets?

Gaskets can be a washer, pad, strip, sheet, or intricately cut shaped piece of material placed between two surfaces to create a low-pressure seal preventing the leakage of liquids or gas and to seal against the intrusion of dust and debris. Neoprene/EPDM sponge is just one of many closed-cell materials on offer from our vast catalogue, it is very versatile and used to manufacture a number of our products, including gaskets.

Neoprene/EPDM sponge is one of ASG’s stock materials, held in block, sheet and roll form in a range of thicknesses starting from as little as 1mm thick, ensuring gaskets can be produced within a minimum timeframe.   Neoprene/EPDM sponge gaskets can be manufactured in any form from a basic square picture frame, to more intricate shapes containing cut-outs, bolt holes and notches, with a choice from a range of finishes including foils, self-adhesives or laminated with other materials.

    Gaskets

    Here at Advanced Seals & Gaskets, we offer a variety of gaskets in an array of materials such as EPDM, Silicone, Solid rubber, Cork, Felt & Textiles, Plastics, Polyethylene, Polyurethane and PVC foam as well as many more. All of our gaskets are made in house with specialised machinery such as one of our many presses or CNC oscillating knife which can cut out your gasket directly from the drawings. Gaskets are designed for a variety of uses from filling gaps, create an airtight seal on pipes or to reduce unwanted rattles and vibrations.

    Why use Neoprene/EPDM Sponge Gaskets

    Our Neoprene/EPDM blend sponge gaskets are manufactured from a high-quality blend of chemicals - Polychloroprene (Neoprene) and Ethylene Propylene Diene Monomer (EPDM), this combination creates a highly versatile material suitable for applications where a stable, flexible and durable material is required. 

    Neoprene/EPDM blend offers resistance to UV light, ozone exposure and weathering, its 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 washers are suitable for most internal and external applications for example heating & ventilation, white goods, automotive, electrical, sealing, etc

    Different Grades

    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.

    Benefits of Neoprene/EPDM Sponge Gaskets

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

    Advantages of Using Neoprene/EPDM Sponge Gaskets

    There are many advantages to using neoprene/EPDM sponge gaskets in your project, not only does it have excellent sealing capabilities under compression, its closed cell structure prevents the growth of bacteria and mould, it has noise and vibration insulation properties and will easily hold a number of self-adhesives, foils and other coverings.

    Neoprene/EPDM blend gaskets have a wide operating temperature range and both the mechanical and chemical properties of both materials.  As this material is stocked in block form, we can split the material down into any desired thickness starting from just 1mm, or laminate layers of material to create a greater depth where required.
