Advanced Seals & Gaskets Ltd supply a vast and complex range of neoprene sponge extrusions in many formats from simple cylindrical neoprene rubber cord to complex contoured parts, all designed to provide protection, prevent the leakage or ingress of air, fluid or gas and to be aesthetically pleasing as edge trims or buffers.
Our customers commonly request their extrusions to be produced in neoprene sponge due to its good water, oil and environmental resistance, along with the physical strength, durability and versatility of the material. All our neoprene extrusions are made to order and are produced using dimensions, samples or drawings provided by customers, from which a tool or ‘die’ is made and a sample produced for approval, ensuring the final product perfectly fits the application.
Neoprene rubber extrusions are preferred in applications where there is exposure to water, chemicals and oil such as construction, aerospace, automotive, marine and agriculture.
What is a Neoprene Extrusion?
‘Extrusion’ is the process of turning material in this case neoprene sponge into a specific shape using an extruder machine that works using high pressure and a die (a shaped tool). This machine pushes raw material through the die creating the finished extruded rubber profile, in continuous lengths, with a consistent cross-sectional shape as per the customer's design running throughout.
Neoprene extrusions can be made as a ‘solid’ shape such as a cord, or ‘hollow’ where a hole, usually in the centre runs through the entire length of the extrusion just leaving the outer wall. Some of the most commonly used neoprene rubber extrusions are D-sections, P-sections, door seals, window seals, U-channels and cords, many of which can be supplied with a self-adhesive finish.

Extrusions are available using many materials including EPDM, neoprene, nitrile, silicone and Viton. Although the production process is the same, each material has its own unique properties suited to different applications. If you need help choosing the material or type of extruded profile you need, please give a member of our sales team a call who will be happy to discuss the available option.
Why use Neoprene Extrusions?
There are many different forms and profiles of neoprene seals, including neoprene sponge extrusions, all produced using the exact same material and possessing the same mechanical properties making it a popular choice across many industries.
Neoprene is an excellent material for 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 extrusions are resistant to oil, chemically inert, flame retardant and have a wide working temperature range of -40ºc to +115ºc Neoprene sponge available in a number of grades, all of which can be extruded to form a profile of your choice.
Neoprene sponge extrusions can be found used within many outdoor, building & construction, glazing, electronic, defence, aerospace and automotive applications for sealing and cushioning against vibrations and rattles.
Advanced Seals & Gaskets work closely with a number of high-quality material manufacturers, giving our customers a choice of grades when buying their neoprene extrusion. Neoprene sponge extrusions can be produced in medium density, firm, flame retardant and EPDM/Neoprene blended grades.
Firm Grade Neoprene sponge extrusions 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 extrusions 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. Advanced Seals & Gaskets work with many material manufacturers and suppliers, giving our customers more choice when designing their neoprene rubber seal. Neoprene rubber seals can be supplied in a number of grades and hardness’s, some of the main ones being:
Please get in touch if you are unsure which grade of neoprene sponge or type of extrusion you require for your application, samples of our materials are readily available for handling and testing purposes.
Benefits of Neoprene Extrusion
- Oil & chemical resistant
- UV, Ozone & weathering resistant
- Flame retardant
- Sound/vibration absorbing
- Closed-cell which prevents bacteria & mould growth
Advantages of Using Neoprene Extrusion
There are a number of advantages to using a neoprene sponge for your extrusion and sealing needs. The material itself is long-lasting, with a wide operating temperature range, it can be utilised for many indoor and outdoor applications, is easy to cut and extrude into complex-shaped profiles and will hold self-adhesive and other backings well.
Under minimal compression, neoprene sponge provides excellent dust, air and watertight seal as well as good resistance against oil. Being a flexible and robust material, neoprene extrusions are suitable for use within many automotive, glazing, electronic, lighting, ventilation, marine and building/construction applications.
