Plastic Extrusions

    What are plastic extrusions?

    Plastic extrusions are produced by raw plastic being melted and formed into a continuous profile by forcing the molten plastic through a die which then becomes hard as it cools.

    Our experienced team has produced plastic extrusions ranging from a 2mm cord to a 125mm wide section as well as parts with various wall thicknesses so are well experienced to help with your plastic extrusion projects whether big or small, rigid or flexible plastic extrusions.

    As an experienced UK plastic extruder, we produce extrusions for OEMs, fabricators and distributors alike — see why customers choose us as their plastic extrusion supplier.

    Flexible Plastic Extrusions

    We manufacture flexible plastic extrusions in a range of materials, with differing hardnesses, properties and colours. You can see our full list of materials here, but do please contact us to discuss any other materials not listed.

    Rigid Plastic Extrusions

    We specialise in crafting high quality rigid plastic extrusions, ranging from basic U-channels to intricate sections. 

    Commodity plastics are commonly used to manufacture rigid plastic extrusions, such as polypropylene (PP), polyethylene (PE), and polyvinyl chloride (PVC), but the choice of material is driven by your specific application.

    Whether opting for more common choices of materials or exploring high or engineering-grade options, as an exerienced plastic extrusion supplier we can provide expert advice tailored to your needs. Talk to us to ensure the optimal material selection for your extrusions.

    Extruded Profiles

    Extruded profiles are continuous lengths of plastic formed to a fixed cross-section, cut to the size your project needs. Because the shape is set by the extrusion die rather than a mould, extruded profiles are an efficient way to produce trims, seals, channels, edging, tubing and bespoke sections in long runs with consistent quality.

    We produce extruded profiles in a wide range of materials, including PVC, ABS, acrylic, polycarbonate, HDPE and TPE, in flexible, rigid and co-extruded forms. If a standard shape does not fit your application, our team can help you develop a custom plastic extrusion from your drawing or sample, supported by our in-house plastic extrusion tooling and die design services.

    Polymer Extrusion

    What is Co-extrusion?

    For products where a single polymer cannot fulfil the complete product specification requirements, two materials are blended maintaining separate layers of each material at the required thickness. This allows the appropriate placement of each material to deliver the specified product part results. This is used when different properties such as strength, stiffness, wear resistance and oxygen permeability are required.  Visit our co-extrusion page to read more.

    We also have the capability to produce not only co-extrusions but tri-extrusions as well i.e. processing 3 materials together.

    Please contact our team should you wish to talk about co-extruded or tri extruded plastic extrusions.

    Frequently asked Questions

    What does polymer extrusion mean?

    Polymer extrusion means melting plastic material and forcing it through a die to form continuous shapes or profiles. This process produces both rigid and flexible plastic extrusions with precise dimensions, used in industries including construction, automotive, and marine.

    What is a flexible PVC extrusion?

    A flexible PVC extrusion is a type of plastic profile produced by melting and forcing flexible PVC material through a shaped die to create continuous, bendable sections used for seals, trims, and cushioning. Profile Techniques manufactures a range of flexible plastic extrusions tailored to hardness and colour requirements.

    What industries use flexible plastic extrusion products?

    Flexible plastic extrusion products are used across multiple sectors including construction, caravan, marine, and automotive. Their adaptable properties make them ideal for applications where flexibility and resilience are needed, such as weatherproof seals and edge protection.

    What are rigid plastic extrusions and how are they used?

    Rigid plastic extrusions are stiff, durable profiles made by extruding commodity thermoplastics (like PVC, PE, or PP) through a die. At Profile Techniques, these are used for structural profiles, frames, channels, trims, and other robust components.

    Can I get custom plastic extrusion profiles made?

    Yes. Profile Techniques Ltd specialises in bespoke plastic extrusion profiles — from design support to manufacture in PVC, ABS, polycarbonate and more — allowing customers to specify material, shape, and colour for their application.

    What is the difference between flexible and rigid extrusions?

    The key difference is material flexibility: flexible plastic extrusion profiles remain bendable and elastic for sealing or protection uses, whereas rigid plastic extrusions are stiff and load-bearing, suitable for structural applications. Profile Techniques can produce both in a range of materials depending on project requirements.
