For most items made from plastic, we can find out:

 

What materials were used to manufacture it?
 
Are the same materials used throughout, or are there layers of different materials? (e.g. lamination, coextrusion, or coatings.)

 

We can determine the structure including the thickness of the layers, and show the results in a cross-section diagram, e.g.:

 

 

In some cases, we can measure the amount of specific additives in the material mix.

 

Materials analysis is done using various techniques including:
Fourier-Transform Infra-Red Spectroscopy (Transmission and ATR), Differential Scanning Calorimetry, chemical tests, microscopy etc.

 

There are some limitations to analysis of materials and structure. Please feel welcome to discuss your requirements with us so that we are aware of the most important points you need to know.
