Neoprene / EPDM Sponge Seals
Advanced Seals & Gaskets offer many products as a solution to your sealing requirements, including those made using a Neoprene/EPDM blend sponge. Neoprene/EPDM sponge seals are available in the form of gaskets, washers, O-rings and extrusions, all designed to prevent air, fluid or gas leaks.
All our neoprene/EPDM blend sponge seals are made to order and available in almost any given size, shape or format, produced by using customers samples or drawings, ensuring the final product perfectly fits the application.
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 within many applications and industries.
What are Neoprene/EPDM Sponge Seals?
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 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 sponge seals can take the form of cut gaskets, strips, washers, extruded profiles and cord, all manufactured using the same closed cell sponge which 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 which assists with holding the seal in situ.

Why use Neoprene/EPDM Sponge Seals?
Our Neoprene/EPDM blend sponge seals are available in many different forms, but they all possess 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, 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 seals 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 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 display mechanical and chemical properties of both materials making it a robust and flexible material that will resist deterioration over time.
Neoprene/EPDM blend sponge is easy to convert using a range of methods including bandsaws, presses, oscillating knives and 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
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.
