Neoprene EPDM Sponge Rubber Seals
Advanced Seals & Gaskets offers many products to meet your sealing requirements, including Neoprene/EPDM sponge seals manufactured from a Neoprene/EPDM blend sponge. Neoprene/EPDM sponge seals are available as gaskets, washers, O-rings, and extrusions, all designed to prevent air, fluid, or gas leaks.
Neoprene/EPDM sponge seals are commonly used to seal around doors and windows, providing effective weatherproofing and insulation.
All our neoprene/EPDM sponge seals are made to order and available in almost any size, shape, or format, produced from customers' samples or drawings, ensuring the final product perfectly fits the application. The seals can also be supplied in rolls for convenient handling and custom cutting.
As each form of the seal is manufactured using a different process, ASG has invested heavily in various machinery, allowing us to offer high- and low-volume seals for use across many applications and industries.
We provide prompt and reliable delivery services, ensuring customers receive their products on time.
What are Neoprene/EPDM Sponge Seals?
Neoprene/EPD sponge is just one of many closed-cell materials available in 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.
Neoprene/EPDM sponge seals are a device or substrate that is used to join surfaces together to either act as a separator or a body to prevent liquids, solids or gases from escaping or penetrating the seal.
Our neoprene/EPDM sponge seals can take the form of cut gaskets, strips, washers, extruded profiles, and cord, all manufactured from the same closed-cell sponge that can be compressed, which in turn ‘hardens’ the material to create a secure seal. Many of our neoprene sponge seals can be supplied with a choice of self-adhesives to help hold the seal in situ. For optimal adhesion, surfaces should be clean and free from dust, oil, and other contaminants before installation.

Types of Sponge Seals
Sponge seals are available in a wide range of types, each engineered to deliver optimal sealing performance for specific applications and environments. One of the most popular options is the closed-cell sponge rubber seal, manufactured from a blend of EPDM and Neoprene. Thanks to its closed-cell construction, this type of sponge seal offers excellent resistance to chemicals, ozone, oxidation, and weathering, making it ideal for outdoor applications where a tight seal against moisture, dust, and air is essential. The minimal liquid absorption of closed-cell sponge rubber ensures long-lasting durability and reliable performance, even in challenging conditions.
For applications that require quick and secure installation, self-adhesive backing sponge seals are an excellent choice. These seals are supplied with a strong adhesive backing that bonds easily to a variety of surfaces, ensuring a complete and reliable seal. Available in a variety of thicknesses, shapes, and sizes, self-adhesive sponge seals simplify the sealing process while maintaining high performance and durability.
Neoprene sponge seals are another versatile option, offering flame-retardant properties and suitability for heavy-duty applications. Manufactured from high-quality materials, these seals provide excellent resistance to oils, chemicals, and weathering, making them a preferred solution for demanding industrial and automotive environments. The flexible nature of neoprene sponge allows it to be compressed to form a tight seal in a wide range of applications.
For environments exposed to intense sunlight and weather, EPDM sponge seals are particularly effective. These seals are designed to withstand UV light, ozone, and extreme weathering, making them perfect for outdoor applications and construction projects. The EPDM sponge material remains flexible and resilient, ensuring a secure seal that withstands the elements.
In addition to these standard types, we also offer extruded profiles that can be custom-manufactured to meet your specific requirements. These sponge rubber profiles are available in a variety of shapes and sizes, and are designed to provide excellent resistance to chemicals, ozone, and weathering. Whether you need a plain seal, a self-adhesive backing option, or a specialised extruded profile, we can supply the right solution for your application.
For further information on our comprehensive range of sponge seals, including gaskets, sheets, and extruded profiles, please contact our sales team. We pride ourselves on delivering high-quality rubber materials and sealing solutions tailored to the needs of various industries. Our products are designed to ensure durability, resistance, and a complete seal in any environment, providing you with the confidence that your application is protected.
Why use Neoprene/EPDM Sponge Seals?
Our Neoprene/EPDM blend sponge seals are available in various forms, but they all share the same desirable properties, making them a popular choice across many industries.
Neoprene/EPDM blend sponge is a highly versatile material that offers resistance to UV light, ozone exposure and weathering. It's closed-cell and non-porous, making it air- and water-resistant, with excellent ageing properties, good resistance to acids, and some resistance to oil.
The Neoprene/EPDM blend has a wide working temperature range of -40º to +85º and flame-retardant properties, conforming to UL94 HF1 classification. This combination of properties means Neoprene/EPDM sponge seals are suitable for most internal and external applications, such as heating & ventilation, white goods, automotive, electrical, and sealing.
The Advantages of Using Neoprene/EPDM Sponge Seals
There are many advantages to using neoprene/EPDM sponge seals 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 seals have a wide operating temperature range and exhibit the mechanical and chemical properties of both materials, making them robust, flexible and resistant to deterioration over time.
Neoprene/EPDM blend sponge is easy to convert using a range of methods, including bandsaws, presses, oscillating knives, kiss-cut presses, and extrusion methods. They're allowing us to produce seals in just about any size and quantity.
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
Different Grades of Neoprene Available
Advanced Seals & Gaskets work closely with several high-quality material manufacturers and stock a range of neoprene sponge grades, including blended varieties, 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 water-tight 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 vast 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.
