The process is ideal for the manufacture of simple or complex shapes and because wall thicknesses can be accurately controlled the process lends itself very well to a wide variety of applications.

Polyethylene Materials

We work exclusively with LLDPE polyethylene which is sourced from 4 main UK suppliers. We stock 12 standard colours however if a customer wants something bespoke for their project our suppliers are usually able to colour match to a RAL or Pantone reference. The cost increases due to it being a non-standard colour but generally it is always possible to do. All of our stock polymer is medium density
