Material Properties

Our ISO 17025 physical testing laboratories provide a comprehensive range of testing services for plastics and rubber materials, to various national and international standards.

It is critical for manufacturers to understand the performance properties of their intended or selected material. Our physical testing services will allow product developers and manufacturers to gain a greater understanding of their materials, and enhance quality control. Our expert team can:

  • Create a custom testing programme to enable you to uncover specific properties of your material
  • Help you select an appropriate material for your project, or validate that your existing material choices are suitable
  • Provide proof that material properties comply with standard legislation
  • Assist in the development of new materials, tailored to the properties required for your project
  • Identify the root cause of material failure

Our most common tests and products are listed below:
