Recycling might cause changes to polymer properties. For example, shear and heat can cause degradation, impurities can weaken materials. Therefore, quality control of the recycling materials is of high importance if the recycled material is targeting demanding applications.

Malvern Instruments range of

  • Kinexus rotational rheometers
  • Rosand capillary rheometers
  • Viscotek dilute solution viscometer

Viscotek SEC/GPC systems allow testing of DMA, rheological properties, molecular weight distribution, molecular structure and intrinsic viscosity. The multi-detector SEC/GPC provides additional insight into degradation products, additives or impurities present. The combination of different technologies provides a more complete picture of your recycled polymers.

Where applicable, the Mastersizer and the Morphologi G3 can be used to measure fillers such as milled glass fiber for their size and shape distributions.
