Biopolymer processing

The numerous plastics now available on the market that are produced using renewable raw materials (bioplastics) display a broad range of characteristics. There are, however, certain drawbacks thewhich restrict a wide-scale use of such materials in long-lasting applications – for example, in housings for electric devices, or in automobiles.
The TITK develops solutions that largely eliminate such disadvantages.


Measures here include:

  • Improving fire resistance through the incorporation of selected flame retardant additives
  • Adjustments to mechanical and thermo-mechanical profiles through fibre reinforcements
  • Improvements to light and UV-fastness through the use of appropriate stabilisers
  • Implementation of various colour effects with bio-based or photochromic pigments and dyes


The equipment available at TITK technical centres and labs enables a rapid and comprehensive analysis of each task to be performed.
