VESTOLIT P 1300 K
Polyvinyl chloride for thermoplastic processing
VESTOLIT P 1300 K is a processing aid for calendering based on high-molecular weight emulsion (E) PVC. Because of its high molecular weight VESTOLIT P1300 K increases the viscosity of the melt causing a faster plastification and smoother running in the calender nip. The occurrence of flow lines is reduced or avoided altogether.
VESTOLIT P 1300 K is used advantageously in the production of thick film gauges where both the inclusion of air and the tendency to stick to the rollers is reduced.
VESTOLIT P 1300 K improves both slip and antiblocking properties and serves as de-stapling device for cut to size film. Addition levels are normally 0.5 %.
Additions levels of up to approx. 1.5 % will normally not affect transparency.
