Product advantages

  1. Using Qingdao Yishibao Plastic Co., Ltd. melt blown material to add Qingdao Yishibao electret masterbatch sprayed melt blown cloth after corona treatment, the filtration efficiency is above 95%, effectively blocking droplets, dust, viruses, etc. below micrometers, At the same time, the filter has a long-term effect of more than 1 year, high charge retention rate and good stability.

  2. The sprayed cloth is soft, not brittle, and flexible.

  3. Complete third-party testing qualifications: stable melt index (1400-1600g/10imn), can provide: reach-205 items, melt index, ash, volatile matter, molecular weight distribution, peroxide residue, FDA SGS test report. Polypropylene meltblown special material has stable high fluidity, environmental protection, narrow molecular weight distribution, low ash content, no other product residues, excellent spinning performance and other excellent characteristics, which meet the standards of the number of fibers per unit area and surface area of the core of medical masks .
