• PES 1003 Viscosity Enhancer increases molecular weights of polyesters.
  • The reaction rate of Masterset PES 1003 Viscosity Enhancer depends on temperature and the residence time.
  • In APET extrusion, sometimes final IV decrease to the levels lower than 0.550 dl/g due to several reprocessing
  • This level of IV causes brittleness in APET even at room temperature.
  • 0,3 %  dosing eliminates brittleness problem
  • PES 1003 performs well especially in twin screw extrusion systems
