Walker Rubber have been specialising in Rubber Extrusions since 1941

Walker Rubber are experts in the manufacture rubber extrusions. Our extrusions are commonly used in applications such as noise control, sealing, vibration, impact protection and decorative trim.

We offer a comprehensive range of rubber extrusion products, for all applications, in a wide array of materials and over 2000 current catalogue profiles. If we don’t already have what you’re looking for, we can take your design and produce it for you in as little as 10 days as we offer a rapid and complete extrusion design and manufacturing service from our UK factory.

Our extrusions can also be supplied cut to length, with or without pre-drilled holes, chamfered and even preformed so they are as easy and quick for you to install as possible.

Extrusion Material Range

We can also customise rubber compounds for our customers. The elastomers available in our standard range of extrusions are EPDM, Neoprene, Nitrile and Natural. However, we can also offer Silicone extrusions and coloured options of Neoprene and Nitrile. If your requirement needs a higher performance level, Viton is also an option.

EPDM rubber extrusions are strongly recommended for most external applications. The material promises a long life since it has high UV / ozone resistance. EPDM can also be used at high temperatures up to 135°C but has limited resistant to oils and fats.

Extrusions made from PCR, also referred to as Neoprene, are often considered to be the best all-rounder profiles for general industrial use. Along with a highest usage temperature of 110°C, Neoprene has chemical resistance to many substances, including water, diluted acids, certain solvents, mineral oils, fats and many other industrial chemicals.

Whilst silicone rubber extrusions have comparatively low mechanical properties such as tear resistance, this inert, synthetic rubber is smooth and has excellent temperature resistance up to 200°C. Silicone stays malleable at low temperatures down to -80 ° C and is ozone, UV / weather resistant. Silicone has relatively low flammability and is also well suited to be used in applications such as food production and pharmaceuticals - we can supply extrusions manufactured from materials specifically approved for such use.

Viton extrusions are made from very high-quality fluorine-containing rubber which have good resistance to several chemicals and also to concentrated acids / alkalis. Viton is commonly used at high temperatures, even up to 200°C. Viton is also referred to as FPM or FKM; it has superior properties compared to other rubbers, especially where durability and chemical resistance are concerned.

Types of extruded rubber we can manufacture

Walker Rubber regularly manufacture ‘D’ section, ‘B’ section, Right Angle, ‘T’ profile, ‘P’ profile, Tadpole, Tank strap, Container door seal, Brick grab, Weighbridge seal, Lock gate seal, Cable protector, Wedge profile, Conveyor side skirt and Hatch door seal extrusions. We can also add a self-adhesive surface to facilitate easy installation if required.

We manufacture rubber extrusions for a variety of industries including: Marine, Construction, Agriculture, Aviation & Baggage Handling, Engineering, Dredging, Food, Logistics, Mechanical Handling, Metal Fabrication, Mining & Metals, Energy and Automotive.

We can also manufacture in WRAS approved EPDM which are used in potable water / drinking water applications such as tank seals, dam and gate seals and pen gate seals.

To meet our customers’ high standards and exact requirements, our team of specialists pride ourselves on being able to offer a bespoke, cost-effective solution in unrivalled lead times.

We understand that there is nothing quite like witnessing the manufacturing processes in action; if you would like to visit us to discuss your requirements in detail we would be happy to welcome you to our UK manufacturing factory in Norwich.

FAQs & Everything you need to know about Rubber Extrusions.

How are rubber extrusions made?

Rubber extrusions are lengths of polymeric products with a fixed cross-sectional profile. Extrusions are made by forcing warmed-up synthetic or natural rubber material through a shaped die. As the material flows through the die, it takes on a sectional profile and shape. The extruded profiles are then cured, a process similar to cooking, in a pressurised, high temperature chamber called an Autoclave. The extrusions are then cooled down and cut to length. Once cooled, rubber extrusions maintain their shape so smaller extrusions for example, can be coiled ready for shipment.

As this is done using high-precision equipment in our Norwich factory. Our high quality, dimensionally stable process has been fine-tuned over many years to ensure batch after batch of product meets the appropriate tolerances and physical performance demands of every application.

Who uses extrusions supplied by Walker Rubber?

We use our skill, knowledge and expertise to extrude parts that can be used for a wide range of industries including aviation, automotive, petrochemical, electronics, medical, chemical, civil and structural engineering and so on. Extruded rubber sections can also be used in a wide range of applications in the food and beverage industry, Silicone rubber for example can withstand temperatures of up to 200 degrees Celsius and specific formulations are available to meet almost any requirement.

What is the recommended shore hardness of rubber?

There isn’t a recommended shore hardness, it depends on your application. We usually manufacture from 70 shore which is suitable for most applications. We can extrude from different harnesses as well.

How quickly can I get an extrusion?

We pride ourselves on our fast lead times and rapid response. We can extrude your extrusions in a very short space of time if we already have a die, and we have been known to do so on the same day as your order if we have capacity. The curing and cooling process does take several hours so the minimum turnaround time is usually 48 hours from order to despatch. Our normal lead time, however, is around 10 working days from order to despatch. New profiles are normally designed, developed and samples shipped in 10 working days, but again we can and do work faster if required.

Which rubber material should I use on my project / application?
