New Family of High-Flow Resin Compounds
Ultra-High Melt Flow PP for Nonwoven Fabrics from Sabic
The PP 514M12 material from Sabic Saudi Basic Industries Corporation, Riyadh, is based on phthalate-free and odor-free technology that should offer good processability for melt-blown fibers with high levels of drawability, spinnability and uniformity, according to the manufacturer. The resulting nonwovens are developed to combine high barrier properties and absorption with breathability in thin and lightweight high-performance webs of enhanced conformability and reduced material consumption.
With a final melt flow rate of >1,000 g/10 min, melt-blown fibers made from 514M12 polymer open potential manufacturing possibilities for lightweight and thin nonwovens aiming to provide improved wearability and air permeability, while maintaining very good barrier property. The potential improved absorption and barrier performance of fabrics based on PP 514M12 polymer has also been underscored in hydrostatic head tests, a frequent requirement for specific configurations of spun-bond/melt-blown/spun-bond (SMS) nonwovens for hygiene applications.
Moreover, PP 514M12 polymer with phthalate-free, single-material technology aims to provide high purity and enhanced customer convenience over incumbent melt blown resins and benchmark blends. The polymer resin is supplied in regular pellet form, which facilitates handling, storage and use.
