POLYOLEFIN ADDITIVES | MATERIALS
that the recycling market and streams are highly variable — regionally, seasonally and by consumer demand — the company expects to develop new solutions to support increasing recycled content concentrations and performance demands. “Recycled polyethylene designed for film
applications can exhibit high levels of gel forma- tion and poor processing stability. To resolve these issues, additives must be included in processing as early as possible to prevent thermal degradation during regranulation and to provide appropriate stability for subsequent film extrusion processes. For example, IrgaCycle PS 031 G restabilises rPE films and prevents crosslinking even after multiple heat and extrusion cycles,” said Sties. Further technical challenges foreseen by Sties include contamination of the recycled polymer by residual pigments and waste, as well as other mixed plastics. “Additives will play a key role in enabling high quality performance of recycled materials while mitigating any negative interactions associ- ated with contamination in the material stream.” BASF Plastic Additives recently launched two specific antioxidants as Biomass Balanced (BMB- cert) grades. The additives will enable customers to
produce polymer grades that have a significantly lower product carbon footprint than conventional offerings. As the substitution is based on the International Sustainability and Carbon Certifica- tion (ISCC) Plus mass balance attributed content concept, customers can expect identical product performance with no change to specification or regulatory status (so no requalification required). The company has received (ISCC) PLUS certifica- tion for certain grades of plastics additives pro- duced at manufacturing sites in Kaisten in Switzer-
