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 polyethylene, technically referred to as LLDPE but known in the industry as MDPE. We choose MDPE as it is a versatile, strong material with good impact resistance and yet retains some flexibility. Information about each grade is below.

Polyethylene Grades

Low Density (LDPE)

LDPE is the most flexible, least rigid polyethylene, with good impact, stress cracking and low temperature performance. It is also very resistant to attack by certain chemicals. For further information about the use of polyethylene with chemicals please contact us.

Medium Density (MDPE)

MDPE is a more rigid material than LDPE with good impact, stress cracking and low temperature performance. We find it to be the ideal solution for our own materials handling products, some of which are used and abused indoors and outdoors 365 days of the year. It is extremely rare for this material to crack unless the product has been abused or used incorrectly.

High Density (HDPE)

HDPE is the most rigid material, and we generally recommend this for products such as large water tanks, fuel tanks and similar products requiring increased stiffness and impact resistance.

If you are in any doubt as to material suitability please contact us for further information.
