Meltblown fabrics is an essential material in the production of face masks and other medical protective equipment, with the COVID-19 pandemic highlighting their importance. And at the heart of meltblown fabrics lies a crucial material: meltblown PP.
Meltblown PP, or polypropylene, is a type of plastic that is melted down and extruded to create fine fibers in a non-woven fabric. These fibers have a diameter of less than 10 microns, making them incredibly effective at filtering out particles.
One of the advantages of meltblown PP is its processing stability, which means it can be processed at high temperatures without breaking down. This is important during the production of meltblown fabrics, as the material must be melted down and extruded at high temperatures to create the fine fibers.
Another advantage of meltblown PP is its narrow molecular weight distribution, which ensures consistent quality and performance of the final product. It also has low volatility and excellent fiber uniformity and attenuation resistance.
Dawn Polymer has been at the forefront of the meltblown PP industry for nearly 20 years, with its proprietary meltblown PP production technology covering the entire production process. We plays an instrumental role in the development of Chinese national standards for meltblown fabrics for mask making and is now one of the most important producers of meltblown PP in the world.
Meltblown fabrics made from meltblown PP have various applications in addition to mask making, including air filtration, insulation, oil absorption, and more. They are widely used in industries such as healthcare, automotive, and construction.
In conclusion, meltblown PP plays a crucial role in the production of meltblown fabrics, and its unique properties make it an ideal material for filtering out particles.
