U.S. reporting companies that manufacture products (or have others manufacture products) that contain 3TG metals or their derivatives (tantalum, tin, tungsten and gold) that are necessary to product functionality or production are required to assess their supply chains and report to the SEC on whether those materials are sourced from the Democratic Republic of Congo and adjoining countries. This includes annually conducting a reasonable due diligence inquiry of our suppliers into the source and conflict status of any 3TG metals contained in Avient products that are within the scope of the Act. We require our suppliers to also engage in due diligence of their supply chains and to annually certify the origin and conflict status of the 3TG metals they supply to Avient. 10.8.20

ANTIOXIDANTS FOR METAL/PP-R AND PP-RCT SYSTEMS Plastic systems in contact with metal inserts can also be subject to oxidization. Avient offers antioxidants that act as metal deactivator for PP-R and PP-RCT components fitted with metal inserts.

Trabajando de cerca con el productor, el equipo de Avient recomendó personalizar una fórmula de material de alta densidad como alternativa al metal. Moldear la tapa por el proceso de inyección con este material llamado Gravi-Tech™, proporciona la apariencia, la sensación y el peso del metal y mantiene una percepción premium. El cambio de moldeado de metal a moldeado por inyección también permitiría el ahorro en el costo de procesamiento y un aumento en la libertad de diseño.
