 Measures viscosity of molten plastic, gives a relative indication of molecular chain length.

 


Includes Static and Kinetic C.O.F


Measures effectiveness of treatments applied to allow a surface to be printed.


Thermal analysis of plastic products or packaging materials by Differential Scanning Calorimetry (DSC).

We can measure properties including melting point, melting range, crystallinity, glass transition of many polymers.

 

DSC scans, showing melting peaks of several plastics



Tests how well a plastic is protected against oxidation. It can show if the antioxidant in the plastic has been used up by excessive processing, weathering etc. Performed on the DSC instrument at elevated temperature in oxygen, it measures the time taken for runaway oxidative breakdown to occur.

 

 

Photographs are taken through a microscope.

 

A range of tests from NZS 7603, including the drop test.


Are also available. We welcome suggestions of tests that could be set up if there is sufficient demand.
