Polypropylene PP meltblown special material is based on polypropylene PP, using peroxide degradation and controllable rheology to improve the fluidity and molecular weight distribution of the resin. The melt mass flow rate is 1500g/10min. The product is suitable for the melt-blown non-woven fabric forming process and is the main raw material for the production of polypropylene melt-blown non-woven products. The most important thing in the mask is the melt blown layer, which is mainly to isolate droplets, particles, acid mist, microorganisms, etc.
