Specialists in PVC Profile Extrusion

PVC Extrusions are low-cost, weather-resistant and fire-resistant, making them an extremely popular choice from our range. We often work with PVC because it is a versatile material, which can be made rigid or flexible, depending on the application.

Our PVC Extrusion process can provide standard PVC profiles such as tubes, angles, channels, clip-on edgings and more. We also design and create custom PVC profiles to suit clients bespoke requirements.

Why use PVC Profiles and Extrusions?

PVC (short for Poly Vinyl Chloride) is a thermoplastic, meaning it is easy to mould and shape when heated. It is durable, with good resistance to weathering and chemical corrosion. It is often used on building exteriors.

Rigid PVC (RPVC or UPVC) extrusions are often used for exterior doors, window frames and drainpipes as they are sturdy and strong.

Flexible PVC (FPVC) is made by adding plasticisers and is often used for flexible extrusions such as window gaskets, flooring trims and sealing applications.

Advantages of PVC Extrusions

PVC has great properties for exterior use and it is relatively cheap to produce, making it a popular material commodity. Advantages of PVC include:

  • High durability: PVC has a high density, which makes it very hard and resistant to impact deformation, denting or cracking.
  • Versatility: PVC can be made flexible or rigid depending on the use of plasticisers, making it useful for a wide range of applications
  • Flame Retardance: PVC won’t catch fire, it’s naturally self extinguishing, making it the perfect material for insulating electrical cables.
  • Weather Resistance: PVC doesn’t degrade in rain, wind, UV or ozone exposure (Provided the relevant grade is used)
  • Water Resistance: PVC doesn’t absorb water or degrade under saline solution, which is why PVC is often used in marine industries such as boat building.
  • Chemical Resistance: PVC is largely resistant to most chemicals.
  • Cost Effective: PVC is cheaper than most other plastic materials.
  • Easily recycled: PVC is a thermoplastic, it can be heated and remoulded repeatedly at the end of its product life cycle.
  • Easily Co-Extruded: PVC can be used to create multilayer structures by extruding Both Rigid & Flexible together. Co-extrusion is sometimes used for pipes, cables, seal solutions and even to create a dual colour effect.
  • Long-lasting and Low-Maintenance: PVC requires very little upkeep and can last a long time, which makes it perfect for exterior applications such as doors and window frames.

The Diverse Applications of PVC Extrusion

Both UPVC and FPVC are great materials for extrusions. They are well-suited for applications across construction, retail, transport, marine and manufacturing. Extrusions can be made in many sizes to create wide PVC drain pipes or thin gaskets. Applications include:

  • UPVC Window and Door Trims
  • PVC Drain Pipe
  • Roof Trims
  • PVC Angles and Edging, such as fascia and boards
  • PVC U Channel for capping, cables and wiring
  • Flexible Window Gaskets
  • PVC Tubing and Hoses
  • Trims for Vehicles, HGVs and Motorhomes
  • Railings
  • Boat Fenders
  • Luggage Racks
  • And many more…

Choosing the Right Material for Your Project

Considering materials during the design stage requires careful thought about the properties you require. While PVC is perfect for some applications, it may not be right for yours. We work with plenty of materials to create standard and custom profiles, so take the time to explore.
