Polyplastics plans to launch a 40% glass-reinforced grade of Durafide recycled polyphenylene sulfide (rG-PPS) by December 2025 as part of its mechanical recycling business. The company said it will develop optimal formulations that will play a role in helping to achieve 100% circularity of engineering plastics by expanding the use of mechanically recycled materials in engineering plastics applications.
The first iteration of Polyplastics’ mechanical recycling business calls for collection of glass-reinforced PPS scrap from molders through an open post-industrial (PIR) mechanical recycling scheme. The PPS scrap will be used as a raw material to make Durafide rG-PPS, which will be launched this year.
Strict quality control
In initial processes, strict acceptance inspections will be conducted, and metal will be removed. In later processes, recycled materials and some virgin materials will be reformulated to meet target specifications. The materials will meet the same quality standards as virgin materials.
The open PIR scheme will help customers reduce and effectively re-utilize waste, and also significantly reduce carbon emissions of their products. For now, the raw material from customers will be used for specific grades of Durafide glass-reinforced PPS.
Higher-filled grades in the pipeline
Polyplastics plans to develop a higher-filled grade as the second iteration of Durafide rG-PPS. The company will establish a system to supply it and the 40% glass-reinforced grade to customers in Japan. The re-compounding business and rollout of the open PIR system requires applications as well as the establishment of collection routes. The company seeks to collaborate with its customers as well as companies in the recycling and industrial waste treatment industry.
In the future, Polyplastics will build a “local production for local consumption” recycling chain within each geographic region.
