FreeFlow Z100 and Z110™

Fluoroelastomers

Technical Information
Introduction
Viton FreeFlow Z100 and Z110 are process aids forpolyolefins that reduce or eliminate melt fracture, lower
extrusion pressure, reduce amperage and torque, andreduce die buildup. The two products differ only in therheology of the fluoroelastomer component.

Both Z100 and Z110 take advantage of proprietary
large-particle technology to provide a highly efficient
process aid that performs effectively under a wide
variety of extruder conditions and with formulations thatcause other process aids to function marginally. Z100and Z110 combine improved fluoroelastomer rheology
with polyethylene glycol (PEG) as an interfacial agent tocontrol the fluoroelastomer particle size delivered to thedie. The resulting large particles of fluoroelastomer coatinternal die surfaces more quickly and with lower dosage
levels than do conventional process aids.
Z100 is best suited for the most aggressive mixing
situations, such as:• Direct dosage during production of gas phase LLDPE(1.0 MI or less)• Low concentration masterbatches (typically, 2%
process aid) in LLDPE carrier (5 MI or less)• All extrusion processes (e.g., film, pipe) using 2 MI orless LLDPE and mLLDPE or HDPE, particularly withhigh pigment or anti-block loadings• Extrusion under conditions that promote mixing, suchas high backpressure (from narrow die gaps or tightscreen packs), or high shear screw elements (e.g.,Maddock tips)
Z110 is best suited for applications involving moderate
mixing conditions, such as:• Dosage during production of solution LLDPE (either
direct or via masterbatch)• High concentration masterbatches (2 to 4% processaid), particularly with LDPE carrier• All extrusion processes (film, pipe, etc.) using 3 MI or
more LLDPE, LLDPE/LDPE blends, or LLDPE/LDPEblends• Extrusion under low shear mixing conditions
Both Z100 and Z110 can typically reduce PEG levels infilms by a factor of 3, as compared to conventional PEGbased process aids, resulting from both the overall lower
PPA dosing level and relatively low PEG content in theZ100/Z110. Reducing PEG levels in film can minimize
surface contamination that can lead to printing or sealing
problems.
Advantages• Improved rates of conditioning during start-up of new
formulations on clean dies or purged systems• Improved performance on difficult lines, where otherprocess aids require high levels• Improved additive efficiency, particularly on lines wherefrequent formula changes are made or in formulas
containing multiple additives• Improved economics• Extended running time between die cleanings• Approved for many food contact uses* and suitable forpotable water appliances*** Manufacturer or marketer of products or articles in contact with food must meet
applicable food contact regulations. Contact Chemours for details regarding
suitability of Viton™ FreeFlow™ products in specific food contact applications.
**Appliance manufacturer or marketer is responsible for ensuring appliance meetsrequirements for potable water use.

Formulation Guidelines

Safety and HandlingTo assist in resin formulation, the following can be used asa general guide:

Viton™ FreeFlow™ Z100 and Z110 are considered safe
materials to handle. They are stable at the temperaturesat which polyolefins are formulated and processed.
However, prior to the use of Viton™ FreeFlow™ Z100or Z110 in polyolefins, review the Safety Data Sheet(SDS) and follow the recommendations in the Chemours
technical bulletin, “Guide for Concentrate Preparation andHandling of Viton™ FreeFlow™ PPAs.”
