Viton™ FreeFlow™ Z150

Viton™ FreeFlow™ Z150 by Chemours is fluoroelastomer-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 processing aids 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 (5 MI or less) or can also be used up to 4% 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 (pipe) 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 suitable for potable water appliances and approved for food contact uses. The shelf life of this product is 4 years at storage temperature below 27°C.
