Viton™ FreeFlow™ Z200

Viton™ FreeFlow™ Z200 by Chemours is a polymer processing aid. It eliminates melt fracture, lowers extrusion pressure, reduces amperage & torque and die buildup. It enhances rate of conditioning during start-up of new lines or purged systems and performance on difficult lines or with difficult formulations without the need for high additive levels often required with other process aids. It provides excellent thermal stability (up to 300°C) for cast film lines where polyethylene glycol-based process aids may degrade. It offers improved performance in masterbatches containing pigments or high filler loading and improved resistance to negative interactions with other additives like HALS, fillers, and anti-block. It combines improved fluoroelastomer rheology with a non-blooming and proprietary inter-facial agent to control the fluoroelastomer particle size delivered to the die. Viton™ FreeFlow™ Z200 is suitable for direct dosage during production of gas phase LLDPE (1.0 MI or less) and low concentration masterbatches (typically, 2% process aid) in LLDPE carrier (5 MI or less). It is also designed for all extrusion processes (film, pipe) using 2 MI or less LLDPE and mLLDPE or HDPE, particularly with high pigment or anti-block loadings, extrusion under conditions that promote mixing, such as high back pressure (from narrow die gaps or tight screen packs) or high shear screw elements like Maddock tips. It is approved for food contact uses and suitable for potable water appliances. The shelf life of this product is 4 years at storage temperature below 27°C.
