PolyMirae Company Ltd, a joint venture of Basell and Daelim and leading Asian polypropylene manufacturer and marketer, has introduced a new pelletised high fluidity polypropylene resin which can address the increasing demands of customers in meltblown textile applications.
The new resin, Moplen HP461X, is produced utilising PolyMirae state-of-the-art manufacturing technology combined with advanced catalyst systems from Basell. Moplen HP461X is an ultra-high melt flow rate (MFR) resin offering a narrow molecular weight distribution (MWD), making it an ideal candidate for meltblown fiber and compounding extrusion applications, said GY Ha, technical support manager of PolyMirae. Customer trials have demonstrated that this pelletised PP grade has excellent processability which enables improved performance, he said.
PolyMirae is one of the first Asian producers to offer a pelletised resin for meltblown applications, stressed Ha. The pelletised form is more cost effective for customers. It enables easier handling and better processing as well as excellent property consistency and uniform peroxide concentrations. In addition, the final products that can be produced display superior heat resistance characteristics and improved air filtering efficiency (longer lasting electrostatic charging), he explained.
The very narrow MWD and high degree of resin consistency of Moplen HP461X promote finer fibers and enhance fiber filament thread line continuity, along with reduced dust in meltblown spinning processes. Finer filaments enable deniers to be reduced significantly, with markedly improved barrier performance as well as soft-touch characteristics - which can provide customers with value-added performance in medical and hygiene products.
The high MFR allows processing temperatures to be reduced over standard meltblown materials, which translate into important energy consumption savings. The low smoke, clean running resin also has good thermal and processing stability, plus low gas fading characteristics.
Moplen HP461X is now commercially available in Korea and for export. In export markets, it will be sold via Daelim Corporation in China and via Basell for all other countries.
