Right: Avient has begun making and selling its Cesa non-PFAS process aid in Asia
conversion processes. It enhances process stabilisation at elevated temperatures and provides low discoloration and low plate-out. “As our customers increase their use of recycled
content, we have optimised AddWorks PKG 158 for processability and to enhance the resin for end-of- life plastic recycling,” said Felipe.
Designing a compound for stability under harsh and variable outdoor conditions requires careful formulation and extensive testing to meet the needs of specific applications. Techmer PM has custom UV stabiliser packages for agricultural film that are designed to allow films to last in the field for the growing season and retain tensile properties in extreme environments. The company has also designed UV products for compostable films, which are meant to be installed in the field and used for a year, with the additive tailored specifically for a region, growing season length, and film thickness. Depending on the application, UV packages are designed for various environmental exposures, including pesticide chemicals commonly used in the agricultural industry that standard UV packages cannot survive, the company reports.
Rigid packaging Avient has begun making – and selling – its Cesa non-PFAS process aid in Asia. The product, for use in polyolefin extrusion and film applications, is made without fluoropolymers – which Avient says may make it classifiable as a per- and polyfluorinated substance (PFAS). “Environmental concerns about PFAS are
growing as studies indicate that it can persist in water and soil,” said Pal Shi, Asia, marketing
