Starting with Application Needs

PT1096 combines rutile titanium dioxide with a low-density polyethylene carrier for applications including PE blown and cast films. PT1165 is a white masterbatch for PET, with applications including biaxially oriented PET film, sheet and injection-molded products. Grade selection should consider the base resin, dosage and finished-product thickness, with trials to confirm the required whiteness, opacity and processing performance.

Color masterbatch selection involves shade, pigment dispersion and resin compatibility. PT8178 khaki masterbatch, for example, contains rutile titanium dioxide, organic pigments and low-density polyethylene. It is suitable for applications including PE protective and laminated films, and for coloring PE, PP and PO materials. The final shade and dosage should be confirmed using samples made under the intended processing conditions.

Polytech offers fluorine-free PPA masterbatches. According to its product documentation, PT5149 is designed to reduce melt fracture and die buildup in film processing, including cast film. Performance depends on the resin, equipment and processing conditions, and the appropriate use should be established through production trials. Functional Masterbatch: UV Stabilizer Solutions Polytech offers UV stabilizer masterbatches for PE and PP products, including PT5020-2 for PE processing and PT5022 for PP processing. Product documentation identifies dosage and finished-product thickness as factors affecting aging resistance. Performance should be verified for the intended application
