Viton™ FreeFlow™ Z200

Technical Datasheet | Supplied by Chemours
Viton™ FreeFlow™ Z200 by Chemours is a polymer processing aid. It improves 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 enhances fluoro-elastomer rheology with a non-blooming and proprietary inter-facial agent to control the 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 has a shelf life of 4 years at storage temperature below 27°C.
