K-175 Acrylic Processing Aid
Product instruction
K-175 is an acrylic processing aid with lubricant performance. It can be used separately or with
other processing aid to promote PVC fusion. Its acrylic composition enables K-175 processing aid
to provide external lubrication without imparting the incompatibility often found in PVC compounds
containing conventional lubricants. K-175 processing aid is a valuable ingredient in clear PVC
formulations for applications such as blow-molded containers and calendered or extruded sheet. Opaque PVC
formulations containing K-175 processing aid are used for siding, high-flow injectionmolded parts
pipe fittings and pipe and conduit.
K-175 offers the following product benefits：
? • Enhanced metal release
? • Increased output rates
? • Improved flow
? • Improved thermal stability
? • Reduced downtime for roll or mold cleanup
? • High clarity and brilliance
? • Better parts appearance
? • Less scrap

Fusion promotion: The Brabender fusion curve of K-175 is very similar with that of competitor, but K-175 displays a little shorter fusion time than competitor (Fig.2), which means K-175 could replace the foreign competitor’s product in the process.
