Chinaplas: DuPont showcases sustainable innovations

Chinaplas: DuPont showcases sustainable innovations
Castor oil-based polyamide, PCR-based PET were among the product debuts.

DuPont Transportation & Advanced Polymers (T&AP), a business unit of DowDuPont Specialty Products Division, showcased three sustainable propositions including bio-based materials, e-F.A.S.T. (friction abating sliding thermoplastics) materials and PCR (Post-Consumer Recycled) solutions at Chinaplas 2019.

The e-F.A.S.T. conveyor belt made with the new DuPont Delrin grade provides a true “dry running” solution.

DuPont’s bio-based material is DuPont Zytel RS polyamide, which is made from castor oil – this brings the smart functionalities of Roborock Vacuums to life. Several new material technologies are applied in this smart device, e.g., an LDS (laser distance sensor) cover made from Zytel RS that provides superior mechanical strength compared to traditional polycarbonate material; low warpage supports precision control and operation; excellent colorability with balanced material performance enables great design. Last but not least, the local manufacturing of Zytel RS materials in China could provide a reliable supply source with consistent quality.

Industry 4.0 and manufacturing automation continue to drive material handling equipment growth in the bottling industry. There is an increased demand for conveyor belts that improve productivity, safety and sustainability.

The Regina e-F.A.S.T. conveyor material was introduced by DuPont in close collaboration with Italy’s Regina Chain, a global leader in conveyor chains, belts and components. The new DuPont Delrin polyacetal grade preserves consistently low coefficient of friction over extended periods of time. The e-F.A.S.T. conveyor belt made with the new DuPont Delrin grade provides a true “dry running” solution, promoting sustainability through low-maintenance cost, longer service life, reduced lubricant and energy requirements, and improved safety for the working environment due to drier equipment and floors. The exceptional wear properties of DuPont Delrin also reduce dust and extend the wear life of e-F.A.S.T. conveyor. Further, noise levels are reduced by 50%.

Finally, DuPont’s non-halogen flame retardant PET resin (Rynite RE19036), made with post-consumer recycled resin, helps customers to reduce their environmental footprints. PCR-based materials meet the updated EPEAT (Electronic Product Environmental Assessment Tool) requirements for plastic parts by offering reduced bromine and chlorine content and post-consumer recycled plastic content. Its high flow and low warpage properties allow faster and easier processing, making it possible to produce bigger parts for consumer and industry applications. DuPont’s PCR solution has been successfully applied in printer components.
