Recently, Milliken developed a new type of additive technology. This technology can make certain breakthroughs in the performance of polypropylene impact copolymers and recycled polypropylene resins. According to relevant reports, the new developed masterbatch - DeltaMax It can increase the impact strength and melt fluidity of polypropylene resin as much as possible without affecting the stiffness performance.
Polypropylene (PP), a thermoplastic resin made from the polymerization of propylene. Because of its good toughness, it is often used in the automotive, plastic pipe and other fields. In the processing technology, the choice of polypropylene injection molding machine There is no special requirement, but higher injection pressures (1500-1800 bar) and holding pressures (about 80% of the injection pressure) are usually used in the injection molding process. In addition, high speeds should be selected to reduce internal stress and deformation. injection.
As early as before the new masterbatch DeltaMax was not developed, the application of polypropylene achieved some innovative results. For example, a new type of thermoforming polypropylene grade introduced by Orman refinery and oil industry company (Orpic) can improve transparency. Productivity and overall performance of thermoformed cups, trays and containers; another example is Panasonic's light-diffusing polypropylene resin molding materials that enable complex shapes to be processed. This material enables injection stretch blow molding in addition to injection molding. Molding, made a certain contribution to improve the design freedom.
The new high-performance DeltaMa modifier introduced by Milliken Company can improve the impact resistance of polypropylene resin by optimizing the size of the rubber dispersion zone and area. This modifier can not only increase the melt flow rate by 5 times, Processors increase operating efficiency, and can triple the impact strength of polypropylene resin based on its original impact resistance.
DeltaMa technology also has a very important advantage, that is, can optimize the recovery of polypropylene. Up to now, the limited availability and variability of the high-performance recycle stream has played a certain role in inhibiting the use rate of recycled polypropylene. DeltaMa High-performance modifiers can eliminate impacts by rebuilding impact resistance and melt flow, which in turn can promote the performance of recycled resins to be even better than that of polypropylene-based resins. In addition, DeltaMa can significantly increase polypropylene regrind. The content in the product, to reduce costs and meet the requirements of sustainable materials.
For DeltaMa high-performance modifiers, Milliken said: 'The market has been seeking polypropylene plastics with higher impact resistance and higher melt flow rates, DeltaMa's emergence has solved the polypropylene industry has long been Satisfaction requirements. '
'DeltaMa allows processors to manufacture stronger, newer parts at faster speeds, increase the sustainability of the industry, and provide a range of other processes to increase system cost efficiency and save energy. Driven by e-commerce shipments and higher automotive safety standards, the market has higher requirements for impact resistance of packaging materials. The net effect of DeltaMa is that processors, brand owners, and OEMs can pay close attention at the same time. Sustainability of materials. 'The Patel of Milliken said.
With the advent of new DeltaMa high-performance modifiers, polypropylene resins and composites containing DeltaMa masterbatches are currently available for use in handbags, fruit baskets and other household products, flowerpot lawn and garden products, industrial crates, and batteries. Boxes, etc. In addition, polypropylene can also play its due role in washing machine drums, refrigerator trays, and automotive interior trims.
