PP Y40 | PPH-Y40 | PP Fiber Grade

PP Y40, also known as PPH-Y40, is a polypropylene homopolymer with a high melt flow rate (MFR). The grade combines excellent melt fluidity with good processing stability, making it well suited to high-speed spinning, meltblown processing, and injection molding.

The resin supports efficient melt movement and consistent processing, making it a practical choice for high-throughput manufacturing. It is widely used to produce meltblown nonwovens, mask filter layers, hygiene products, and thin-wall injection-molded components.

Famous Manufacturers of PP Y40

The current mainstream manufacturers include Sinopec Hainan, Qilu Petrochemical, Zhongtian Hechuang, and Sinopec Maoming. Different producers deliver differentiated characteristics through process optimization, such as odor-free grades produced via hydrogen regulation technology or low-VOC grades modified with special additives.
