EPDM/Neoprene Fabrication

Advanced Seals & Gaskets Ltd manufacture various fabricated components from a range of non-metallic materials such as foam, sponge, plastic, cork and rubber, one of the most popular ones being neoprene/EPDM blended sponge. As neoprene/EPDM sponge is one of our core stock materials, fabricated parts can be processed within a minimal lead time using blocks of sponge and specialist machinery, usually a selection of saws, drills, buffers and knives. 

By choosing ASG for your fabrications, you will also benefit from the option of using our CNC oscillating knife, which can automatically cut and drill fabricated parts by reading CAD drawings.  Fabrications are often used as a cheaper alternative to mouldings and extrusions (as there is no initial die/tooling cost) for the production of bespoke shapes, usually required as one-off prototypes or small quantity runs. 

All our fabrications are made to order and are produced using samples or drawings provided by customers, taking many forms for example multiple materials laminating to create composite sheets which are then cut down into gaskets, washers, strips, displays & signage and seals with flexible joints or irregular angles.

What are Neoprene/EPDM Sponge Fabrications?

Neoprene/EPDM  blend 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 high-quality blend of chemicals - 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.  

Fabrication is the procedure of turning blocks or sheets of foam, sponge, and rubber into custom made 3D usable shapes. Fabrications are created using CNC machines, saws, drills, buffers etc, enabling us to create unique products that usually cannot be produced by one single process, where the item is too big to be produced in one single piece, or where 3D profiles are required such as cubes or cone shapes. 

Supplying fabricated parts also allows us to produce composite sheets (laminating multiple layers of different materials together), before cutting out the final shapes.

    Why use Neoprene/EPDM Sponge Fabrication?

    Advanced Seals & Gaskets Ltd have a team dedicated to fabrications and the production of one-offs and complex products to use during design and prototype development or when singular items are required.  Fabrications are often used as a cheaper alternative to mouldings and extrusions (as there is no initial die/tooling cost) for the production of bespoke shapes, these are ideal for use as samples or prototypes prior to paying for expensive tooling for mouldings or extrusions for bulk production. 

    They are also perfect for producing props, signs, displays, packaging case/box inserts with routered out shapes to hold specific items in place.  By using neoprene/EPDM blend sponge for your fabrication needs, you will benefit from the excellent properties and benefits of both materials including 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 fabrications 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 Fabrications

    There are many advantages to using neoprene/EPDM blend sponge fabrications 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 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 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 is easy to convert using a range of methods including bandsaws, oscillating knives and blades allowing us to offer a range of fabricated parts.

    Benefits of Using Neoprene/EPDM Blend 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

    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.
