Bespoke Silicone Rubber Profiles

Viking Extrusions are leading silicone rubber manufacturers with 30 years’ experience producing bespoke and complex silicone rubber profiles.

An Introduction to Silicone Rubber Profiles

Manufacturing and developing new silicone rubber extrusions has been at the core of Viking Extrusion’s business since the company’s inception and the team at Viking Extrusions take pride in their continuous innovation and development of new production techniques.

Viking Extrusions have produced over 8000 silicone rubber profiles for customers and can work closely with you to make sure your requirements are fully understood. The technical team at Viking Extrusions are able to use their vast experience of manufacturing silicone rubber profiles to provide advise on design and take an idea from concept through to production. This includes suitability for manufacture and choosing the right material for your application, ensuring the silicone profile supplied is tailored to your exact specifications.

Bespoke Silicone Rubber Profile – Manufacturing Capabilities

We can offer minimum order quantities as low as 10m depending on tube size and we also have the machinery and capacity to produce large production runs of many thousands of metres. We specialise in the manufacture of complex profile and are able to produce:

Single hollow voids
Multiple hollow voids
Irregular shapes
Small profiles
Large profiles (our maximum tool size is 152mm diameter)

We are able to extrude silicone profiles in a wide range of material grades, from 20° Shore A to 80° Shore A. We can manufacture silicone profiles in all colours. Our production staff are highly experienced in pigmenting silicones to match RAL and Pantone numbers and colour matching customer samples.

As standard our silicone profiles are extruded to ISO 3302-1: 2014 E3 tolerances. However, if required, we may be able to offer tighter tolerances. To discuss your project requirements please contact us to speak to one of our experienced team members. To view our manufacturing tolerances, visit our tolerances page.

Cut to Length Silicone Profiles and Joined Rings

We have a selection of in-house cutting equipment and we can supply silicone profiles cut to any length required. We also have a comprehensive range of joining presses and, we are able to supply silicone rubber profiles either glued or vulcanised into rings of any size.

For more information on our cutting and joining capabilities, visit our Cut to Length Silicone Extrusion and Silicone Rubber Joined Rings pages

Fabricated Silicone Gaskets

As well as being joined into rings, we are able to join profiles into more complex fabricated gaskets, such as picture frame gaskets. This is achieved through using mitre joined or moulded corners.

For more information visit our Fabricated Silicone Gaskets page.

Adhesive Backed Silicone Profiles

We are able to supply silicone rubber profiles complete with adhesive backing tapes applied. Specialist tapes are available on request.

What are the advantages of silicone rubber profiles?

Silicone rubber is an inorganic synthetic elastomer which is made from a cross-lined silicone-based polymer. It offers a unique set of advantageous properties which cannot be matched by other organic elastomers such as:

Non-reactive – Silicone rubber is highly inert. It does not react with the environment or most chemicals, making it the elastomer of choice for food and medical applications.
Resistant to Ozone and UV – Silicone has superior weathering resistance compared to organic rubbers, whose carbon composition leaves them susceptible to UV, Ozone and other ageing factors.
Temperature resistant – Silicone rubber can operate in temperatures from -60°C to + 300°C. Even at extreme temperatures, silicone rubber maintains its mechanical properties such as tear strength, tensile strength, compression set and elongation.

Thermal conductivity – silicone rubber has a higher thermal conductivity than most other rubbers. Silicone rubber with high thermal conductivity can be used to make products such as heating rollers and thermal interface sheets.
Moisture and steam resistance – Silicone rubber can be immersed in cold, hot or boiling water for long periods of time, without its mechanical or electrical properties being affected. Silicone can withstand steam under ordinary pressure, but pressured steam above temperatures of 150°C can cause silicone to breakdown.

We manufacture many different types of silicone rubber profiles – for all applications.

Me manufacture silicone rubber profiles from many different types of compound, and we are confident we will be able to manufacture what you need for your industry purposes. Some of the most popular types of silicone profile we provide are:

General purpose silicone profiles – The most common type of Our general-purpose silicone is FDA approved and can be pigmented to almost any colour.
Platinum cured silicone profiles – Our platinum cured silicone has excellent biocompatibility and is FDA and USP Class VI approved making it suitable for medical and pharmaceutical applications. Platinum cured silicone has high tear strength and transparency and is commonly used in food processing, peristaltic pumps and many other applications.
Heat stabilised silicone profiles – Suitable for applications up to 260°C.
High temperature silicone tubing – Suitable for applications up to 300°C.
Metal-detectable silicone tubing – X-ray detectable silicone used for food processing applications.
Flame retardant silicone profiles – Available to EN45545-2 specifications for rail applications and to FAR/JAR 25.823 for aerospace usage.
Conductive silicone profiles – Semi conductive compound with low volume resistivity, used for electro-conductive parts, EMI shielding and heating elements.
