Neoprene Rubber Extrusion

Advanced Seals & Gaskets Ltd supply a vast and complex range of neoprene rubber extrusions in many formats from simple cylindrical neoprene rubber cord to complex contoured parts, all designed to provide protection, prevent leakage or ingress of air, fluid or gas and to be aesthetically pleasing.

Our customers commonly request their extrusions to be produced in neoprene rubber due to the high water and environmental resistance of neoprene along with the physical strength, durability and versatility of the material.  All our neoprene rubber 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 Neoprene Rubber Extrusion?

Rubber extrusion is the process of turning material in this case neoprene rubber 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 with a consistent cross-sectional shape as per the customer's design.

Neoprene rubber 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 manufactured with a self-adhesive finish.  For further information on our neoprene rubber extrusions, please give our sales team a call.

    Rubber 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 options.

    Why use Neoprene Rubber Extrusion?

    There are many different forms and profiles of neoprene seals, including neoprene rubber extrusions, all produced using the exact same material and possessing the same mechanical properties making it a popular choice across many industries.

    Neoprene rubber 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 rubber extrusions are resistant to oil, chemically inert, flame retardant and have a wide working temperature range of -20°C to +70℃. Neoprene rubber is available in a number of hardnesses and grades, all of which can be extruded to form a profile of your choice.

    Neoprene rubber extrusions are particularly popular for a number of automotive applications including door/boot/window sealing and cushioning against vibrations and rattles.

    Benefits of Neoprene Rubber Extrusion

    • Popular for external & automotive sealing  applications
    • Durable
    • Variety of Grades & profiles available
    • Impermeable to water and dust
    • Moderate resistance to oil, chemical greases and fats.
    • Excellent resistance to ozone, weathering and ageing

    Advantages of Using Neoprene Rubber Extrusion

    Neoprene rubber extrusions are utilised where a durable, strong, abrasive material is required in an environment where exposure or sealing against extreme weather, water, salts, oil grease, UV/Ozone and gases is necessary. 

    Neoprene rubber extrusions create identical cross-sectional shapes products in varying lengths as required by the customer from short, pre-cut sections, right through to rolls of extruded product 100’s of meters long. 

    As neoprene rubber profiles are manufactured using raw material, we have the ability to design and offer bespoke and unique profiles to perfectly match our customer's specifications.

    Different Grades

    Advanced Seals & Gaskets work with many material manufacturers and suppliers, giving our customers more choice when designing their neoprene rubber extrusion. Neoprene rubber extrusions can be supplied in a number of grades and hardnesses, some of the main ones being:

    (BS2752) British standard 2752 is a higher performing, stronger grade of neoprene rubber which offers a wider working temperature range of -30°C up to +120°C, greater resistance to ageing, weathering, acids, inorganic salts, oils and ozone as well as improved strength and anti-abrasion qualities in comparison to standard neoprene.  This grade is available inshore hardnesses of 40°, 50°, 60°, 70° and 80°.

    Flame retardant neoprene rubber extrusions can handle continuous temperatures of -30°C to +100°C, this material meets the test requirements of the flammability standard UL94-V0 and is in line with ISO 340. Flame retardant neoprene rubber sheets are also tested in accordance with anti-static BS 490.  

    Food Quality (FDA) neoprene is white in colour and conforms to EC and FDA regulations for use within the food processing and pharmaceutical industries.  Properties including resistance to fats, greases and vegetable oils, combined with higher tensile strength and wider working temperature range of -30°C up to +130°C make it a popular material to use.

    Please get in touch if you are unsure which grade of neoprene or type of extrusion you require for your application, samples of our materials are readily available for your perusal.
