Baerlocher USA presented additive solutions at the 2021 SPE International Polyolefins Conference

Baerlocher USA, part of the Baerlocher Group, a leading global supplier of plastics additives, is highlighting the contributions of its advanced resin stabilization technology (RST) to the circular economy at the virtual 2021 SPE International Polyolefins Conference, from Feb. 23-24, through the company’s virtual exhibit and presentation on Feb. 23. As a Gold event sponsor, the company is exhibiting detailed information on Baeropol® T-Blend stabilizers, based on Baerlocher’s RST platform, which can help increase the percentage of recycled content that can be successfully incorporated in extrusion blow molded high-density polyethylene (HDPE) bottles and polyethylene (PE) film.

Baerlocher USA’s presentation, titled “Advances in Extrusion Blow Molding of Post-consumer Resin,” is focusing on the use of stabilization to prevent thermal and oxidative degradation of polyolefins during both the mechanical recycling and molding processes. 

“Baerlocher’s long-term commitment to the greater sustainability of plastic materials is aimed at making the circular economy a near-term reality,” said Andreas Holzner, global SPA business head, Baerlocher. “Our approach is based on strategic collaborations with technology companies, polyolefin producers, machinery suppliers, converters, brand owners and industry associations to promote mechanical recycling by stabilizing recyclates. For example, we offer custom stabilization formulations and can work directly with recyclers to stabilize post-consumer resins. These and other initiatives aim to expand the use of recycled polyolefins by improving their quality and consistency.”

Proven Material Performance

The company’s Baeropol® RST, a family of customizable additive blends that work synergistically with phenolic antioxidants to stabilize polyolefin resins, can facilitate recycling in several ways. These additives can help increase the amount of cost-effective recycled content incorporated in resin and film without impacting performance and appearance. They can stabilize low-value consumer film waste during high-temperature melt filtration, enabling the film to be upcycled into a product suitable for reuse in blown film. This technology is also valuable for improving the color of recycled content.
