MOSCOW (MRC) -- Saudi Arabia's National Petrochemical Industrial Company (Natpet) has presented an enhanced polypropylene (PP) impact copolymer grade, Teldene B20ML for injection molding applications, as per Polymerupdate.
B20ML is upgraded by replacing NaBz with Milliken's nucleating agent Hyperform HPN-20E, which offers better shrinkage control and improved stiffness without affecting impact performance.
As said, it now provides better stiffness/impact balance in both machine direction (MD) and transverse direction (TD) orientation. The superior isotropic shrinkage control facilitates a dimensional stability to eliminate warpage.
Together with the improved thermal properties achieved with Hyperform HPN-20E, the new grade also provides downgauging advantage for converters.
The improved B20ML grade is suitable for new market segments, such as large pails and automotive compounding, in addition to conventional food and non-food packaging.
Neaz Ahmed, Assistant Manager Product Application, NATPET, commented, "With the improvements made to Teldene B20ML, we are pleased to offer a more effective and sustainable PP reactor grade to the market, with great potential to add value in new application segments. Customer feedback since we made the switch to Hyperform HPN-20E confirms better quality of finished products and less wastage during production of large pails."
As MRC informed earlier, in mid-December 2015, Natpet shuts its PP plant on account of a mechanical issues. The plant is expected to remain shut for a period of around one week. Located at Yanbu in Saudi Arabia, the plant has a production capacity of 400,000 mt/year.
