EPDM Rubber Extrusion
Advanced Seals & Gaskets Ltd supply a vast and complex range of rubber extrusions in many grades of material and formats, from simple cords 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.
Customers commonly request that their extrusions are produced in EPDM due to its excellent list of resistance and strength properties. All our EPDM extrusions are made to order and are produced using dimensions, samples or drawings provided by customers to ensure the final product perfectly fits their application.
What are EPDM Extrusions?
EPDM is a synthetic rubber, an abbreviation of ethylene, propylene, diene and monomer, a durable rubber popular for use in a range of applications, available of grades and hardnesses from 40°- 90° shore (the shore hardness is measured using a shore durometer which indicates the level of resistance to indentation, the higher number on the scale indicate a greater resistance - harder the material/lower number indicate less resistance- softer the material.
‘Extrusion’ is the process of turning raw material in this case EPDM rubber compound into a specific shape using an extruder machine which 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.
Extrusions can be made as a ‘solid’ shape such as 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 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.

Why use EPDM Extrusions?
There are many different forms and profiles of extrusions that can be found used within various applications for sealing against air, gas and liquid, cushioning against vibrations & rattles and as surface protection. Extrusions are perfect for applications where off the shelf seals and gaskets will not fit and a bespoke profile or shape is required. Extrusions are also the quickest and simplest way to create lengths of identical products even when manufactured in bulk, which is essential for high volume production and assembly.
By using an EPDM extrusion, end users have the benefit of a perfectly fitting rubber profile combined with the properties of the EPDM material which include an operating temperature range of -30°C to + 110°C, resistance to environmental effects of UV rays, O-zone and weathering making this a great material for both internal and external applications.
The Advantages of Using EPDM Extrusions
There are many advantages to using EPDM extrusions within your application, namely its extensive list of properties and the variety of grades available. EPDM rubber is ideal for use where a strong, versatile material is required in an environment where there may be exposure to the ozone, UV, chemicals, water, steam and acids.
EPDM rubber extrusions are readily available in a range of standard profiles, however more complex and bespoke profiles will take longer to supply due to the process of designing and making the tool, testing samples and then making the final product. seals such as mouldings and extrusions will take longer due to the processes entailed.
The tear resistance of the material allows the extrusion to be produced, cut down and pushed into position without damage or distorting the final product or causing the seal to fail.
Benefits of EPDM Seals
- Ozone and Weather Resistant
- Variety of grades and hardnesses available
- Resistance to Fine Particles
- Can be extruded into bespoke designs
- Creates an air and watertight seal
Advanced Seals & Gaskets work with many material manufacturers and suppliers, giving our customers more choice when designing their EPDM rubber extrusion, other grades available include:
FDA grades - Food quality EPDM is available in blue and white options. This synthetic material is suitable for use in food and pharmaceutical processing applications. Food quality EPDM offers good resistance to animal and vegetable oils, iis non-toxic and has a working temperature of -25°C up to +140°C.
WRAS approved EPDM rubber seals are suitable for use in potable water applications (water for human consumption) The material is resistant to weathering, ozone, ageing and chemicals and meets standards BS 6920-1:2000 and BS 6920-1:2014. WRAS approved EPDM has a working temperature of -40°C up to +120°C.
Peroxide Cured - Vulcanising or curing EPDM using peroxide (as opposed to Sulphur) produces a more superior material with higher temperature resistance, heat resistance and improved oil and chemical resistance, this material is suitable for demanding applications such as nuclear facilities.
Please get in touch if you are unsure which grade of EPDM or type of extrusion you require for your application, samples of our materials are readily available for your perusal.
