Neoprene Foam Sheet

Neoprene Foam Sheet

Here at Advanced Seals & Gaskets, we offer a vast catalogue of sheet materials, including neoprene sponge, also sometimes referred to as neoprene foam, neoprene sheet or neoprene sponge rubber sheet. Our neoprene sponge products are converted from blocks using our state of the art splitting machines, meaning we can supply neoprene sponge sheets in thicknesses starting at as little as just 1mm up to 40mm without laminations, in a standard 2meter x 1meter size.

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

Parts produced using neoprene sponge sheets can be used for sealing against dust, air and moisture, gap-filling between uneven surfaces or for reducing unwanted noise and vibration.  They are also preferred in applications where there is exposure to chemicals, oil and petrol.

What are Neoprene Sponge Sheets?

Neoprene sponge rubber  (also referred to as Polychloroprene) is just one of many closed-cell materials on offer from Advanced Seals & Gaskets vast catalogue. This material is very versatile and used to manufacture a number of our products, including sheets. 

Neoprene sponge is one of ASG’s stock materials, held in a block, sheet and roll form in a range of thicknesses starting from as little as 1.5mm ensuring sheets can be supplied within a minimum timeframe.  Rolls are sometimes preferred by customers as they have the freedom to cut their own sheets in various sizes as and when they are required. 

Neoprene sponge sheets can be manufactured with a choice of finishes including foils, self-adhesives or laminated with other materials.

    Why use Neoprene Sponge Sheets?

    Neoprene sponge sheets have a number of desirable properties making them a popular choice for use as a sealing, gasketing and insulating material. Its closed-cell structure creates an air, dust and watertight seal, with both sound and vibration insulating properties.

    Neoprene sponge rubber sheets also have great longevity compared to other materials thanks to their excellent ageing properties, being resilient to ozone, sunlight, oxidation and UV exposure. 

    Neoprene sheets are resistant to petrol, oil, chemically inert and flame retardant, therefore found used within many building & construction, glazing, sealing, electronic and automotive applications.


    Here at Advanced Seals & Gaskets, we offer a variety of sheets 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 sheets are cut to the customer's desired length and thickness in-house with specialised machinery and supplied with a choice of finishes each with unique properties suited to individual applications.

    Benefits of Neoprene Sponge Sheets

    • Oil, petrol & chemical resistant
    • Durable
    • UV, Ozone & weathering resistant
    • Flame retardant
    • Sound/vibration absorbing
    • Closed-cell which prevents bacteria & mould growth

    The Advantages of Using Neoprene Sponge Sheets

    There are many advantages to choosing neoprene sponge sheets in your application.  The material itself is long-lasting, with a wide operating temperature range of  -40ºc to +115ºc  coupled with being UV, Ozone & weathering resistant, which means it can be utilised for many indoor and outdoor applications. 

    Neoprene sponge is one of ASG’s stock materials and therefore sheets of any thickness and finish can be turnaround within a minimal timeframe, ready for our customer to convert into a range of their own products.  Under minimal compression, neoprene sponge sheets offer excellent dust,  air and watertight seal as well as good resistance against oil.  

    Being a flexible and robust material, neoprene sponge sheets are suitable for use within many automotive, glazing, electronic, lighting, ventilation and building/construction applications.

    Different Grades

    Advanced Seals & Gaskets work with a number of material manufacturers, meaning our customers benefit from a choice of grades when using neoprene sponge sheets.  Neoprene sponge sheets can be supplied not only in our medium density Neoprene but also in a Flame Retardant, Firm grade and EPDM/Neoprene Blended grade.

    Firm Grade Neoprene sponge sheets are closed-cell, fire resistance tested to FMVSS 302, and have a density of 180kg (+/- 25), this means they are suitable for use in more heavy-duty applications, where less compression is needed to create a tight seal.  

    Flame Retardant Neoprene sheets 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.  

    EPDM/Neoprene Blend sponge is an extremely versatile material, combining the properties of both types of sponge, excellent weathering and outdoor resistance of EPDM and the oil/chemical resistance of neoprene, making it the ideal choice for many outdoor sealing applications.    

    Please get in touch if you are unsure which grade of neoprene sponge you require for your gasket or would like samples for your own tests.
