Material development

Material properties via recipe and process

  • formulation and process
    • copolymers
    • chain structure
    • Molar mass distribution
  • additivation and stabilization
  • reactive blending

Characterization and testing

  • molecular characterization
  • material testing

Conventional plastics

  • new building blocks
  • polyesters, polyamides, PUs, acrylics,
    styrenics, cationic and anionic polymers (polyelectrolytes)

Bio-based plastics

  • validation of new building blocks
  • testing of raw material qualities
  • adaptation of properties to target markets

Process development

 

The manufacturing process of a polymer has a decisive influence on performance and costs of the corresponding plastic. We develop safe polymerization processes that meet economic and ecological requirements.

Polymerization processes

  • solution and bulk polymerization
  • emulsion, suspension, precipitation polymerization
  • inverse emulsion polymerization
  • non-aqueous heterophase polymerization (O/O emulsions)
  • reactive extrusion

Process analysis

  • elaboration of the characteristics
  • calorimetry (automatic reaction calorimeter RC1)
  • inline particle size and visualization (FBRM and video microscopy)
  • reaction tracking by means of inline IR

Process optimization

  • more efficient processes
  • safer processes
  • better products

Scale-up and sample quantities

  • process analysis
  • preliminary investigations for scale-up with focus on process reliability
  • scale-up from laboratory to pilot plant scale (up to 10kg)
  • provision of sample quantities
  • process analysis
 

In the synthesis pilot plant of the Fraunhofer PAZ, polymer syntheses up to the ton scale are possible.
