Processing Aid

PolyOxyter^®, an additive masterbatch product, has been specially formulated with reactive compounds to provide performance enhancement and processing improvement for Polyesters, Nylons, and Polycarbonates. The product has been formulated to provide performance enhancement in both extrusion and molding processes. 

When used at a typical 3% to 7% let-down, PolyOxyter has been shown to produce many impressive benefits, such as: a widened processing window, improved compatibility between dissimilar resins, controlled crystallinity and often crystallinity reduction, elimination of weld lines & war page, frost line elimination and scrap reduction, stabilized melt viscosity, improved printability, improved dispersion of additives, increased loading capacity for fillers and additives, improved adhesion properties with polar surfaces, reduced hydrolytic breakdown, and enhanced clarity. PolyOxyter is also an excellent material to improve the properties of packaging materials. When used as an additive, the product can be co-extruded into multi-layered film to produce the following additional benefits: improved vapor barrier properties for enhanced resistance to moisture, oxygen, and carbon dioxide penetration, and improved interlayer film adhesion. Benefits of PolyOxyter when used with PET applications have been found to be: crystallinity control in the stretching process, reduced hydrolytic breakdown, improved surface adhesion, and optical compatibility. 

PolyOxyter^® is co-extrudable with PET in cast and blown film operations, and can be applied by solution coating on PET for flexibility. PolyOxyter^® has a specific gravity of about 1.2, and is available as a uniform pelletized shape, resembling a clear bead. The product has excellent compatibility with most any amorphous polymer system, such as polyester, polyamide, polycarbonate, polysulfone, polyethersulfone, polyketone, and many others. PolyOxyter^® is manufactured using FDA compliant ingredients.
