Plastic Extrusion Materials

 

The choice of thermoplastic material needs to be carefully considered depending on the application use. Some extrusion materials are UV stable and have higher heat resistance, give good clarity (PETG) or are more flexible than others.

We are a plastics and PVC extrusions specialist and use a variety of materials. The properties of the more popular ones are shown including UPVC (Rigid PVC), Cellular PVC, flexible PVC, ABS, HIP (Polystyrene), Polyethylene, Polypropylene, Polycarbonate, PC/ABS alloys, Nylon 6 and Clear PETG.

This list is not exhaustive and we are always trialling new extrusion materials. If your specific requirements are not shown on either of our extrusion material pages, please contact our Technical Sales Representative.
