HITEMA 61720 AP is a masterbatch in a polypropylene carrier which contains a third-generation polymer processing aid additive especially chosen because of its high effectiveness and performance, even under extreme processing conditions. It features an outstanding performance, through the whole range of processing conditions, getting rid of the melt fracture, decreasing the melt pressure, reducing the power consumption, and the die build-up.
Improves the PP extrusion no affecting both the mechanical and optical properties nor the sealability, adhesion and printing of the film.
The product shows a superb thermal stability, ideal for CPP film production lines, where the conventional PPA additives are prone to degradation.
Increase the dispersion ability of both pigments and fillers into the film.
Shortens the conditioning times during both the startup of new production lines and during product run changes.
Improves the processability of low-MFR polymers.
Highly stable under very demanding processing conditions where the polymer has to face way high temperatures and high shear stress.
