Viton™ FreeFlow™ Z150

Technical Datasheet | Supplied by Chemours
Viton™ FreeFlow™ Z150 by Chemours is a fluoro-elastomer-based polymer process aid. It improves rates of conditioning during start-up of new formulations on clean dies or purged systems. It enhances performance on difficult lines, where other require high levels in the broadest range of shear rate. It increases additive efficiency, particularly on lines where frequent formula changes are made or in formulas containing multiple additives. It helps in extending running time between die cleanings. It reduces die build-up, die-pressure, amperage, torque, melt fracture. Viton™ FreeFlow™ Z150 is used for low concentration masterbatches (typically, 2% process aid) in LLDPE carrier with MI of 2 or more and can also be used in highly-concentrated masterbatch. Recommended direct dosage during production of gas phase LLDPE (1.0 MI or more), solution phase LLDPE (either direct or via masterbatch) and all extrusion processes using 3MI or less LLDPE, mLLDPE or HDPE, LLDPE/LDPE blends, or LLDPE/LDPE blends, including also pigment or anti-blocking agent. It is also suitable for potable water appliances and approved for food contact. It has a shelf life of 4 years at storage temperature below 27°C.
