Extrusion International 4-2019

36 Extrusion International 4/2019 RAWMATERIALS – INTERVIEW Brand New Solutions to Meet Customer Needs DuPont, a global innovation leader, regularly launches brand new advanced material solutions based on the needs of customers and gaps in the industry. This commitment to customers is a major driver for the company, enabling it to continuously develop and introduce a steady stream of new cutting-edge technologies to the polymer market. Christophe Paulo, marketing manag- er, DuPont, spoke about a new-gen- eration silicone-based masterbatch for filmprocessing improvements and new pelletized grades for pellet ex- trusion modeling. Mr. Paulo, please tell us more about DuPont’s innovative solution for packaging application. This year, DuPont Transportation & Industrial, a global business unit of DuPont had several, brand new launches for the polymer market to fill some of the gaps they are seeing in the plastics industry. One product introduction, new DOW CORNING™ AMB-12235 masterbatch combining anti-block and slip for polyethylene (PE) blown film, took place at China- plas 2019 in Guangzhou. Based on actual customer needs, DuPont is focused on expanding its solution offering for packaging ap- plications, to enhance processing and final product transformation, like printing on the film, for instance. When customers asked us for a sim- pler way to optimize PE film process- ing, we developed this innovative, high-performance, combined mas- terbatch. To achieve the best level of slip performance for the film one needs to combine the anti-blocking and slip properties which is very chal- lenging. We have been working to develop a product with an appropri- ate combination of the two proper- ties to guarantee long term slip and anti-blocking characteristics at the same time. As a result, DuPont for- mulated DOW CORNING™ AMB- 12235 masterbatch ensuring com- patibility between the anti-block and slip properties. It provides the best ratio of active ingredients and helps film makers avoid spending time and effort to calculate the right combina- tion and amount of each additive by trial and error. DOW CORNING™ AMB-12235 mas- terbatch, which is approved for food contact in Europe, the United States and China, is the latest addition to the new DuPont portfolio of silicone- based solutions that extend proper- ties, enhance processing and reinforce materials. This brand new additive helps lower the COF of blown film to reduce its resistance to sliding over itself or manufacturing rollers. The improved slip performance – which is stable overtime and under high tem- peratures – contributes to increased production speed, uninterrupted throughput and uniform film quality. Unlike organic slip additives, DOW- CORNING™ AMB-12235 masterbatch
