Polymer processing

Discontinuous polymer processing

Internal mixer (50 cm3 – 300 cm3 chambers)

  • Collecting of torque-time-temperature-diagrams during the mixing process
  • Reproducible determination of Black Incorporation Time (BIT) according to Cotten
  • Creation of temperature corrected torque-time curves and determination of the degree of property conservation 
  • Measurement of the electrical conductance for the visualization of dispersion and distribution of carbon black

Laboratory roller mill

  • Homogenisation and compounding of rubber recipes 
  • Mechanical and thermal stress and activation of rubber powder
