Viscosity Enhancer

Viscosity Enhancer

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
