产品介绍

Thousands of melt-blown manufacturing plants with mixed levels have been set up under the COVID-19 epidemic situation in 2020. The market is oversupply, Customers are getting more and more picky on product performance, from initially appearance looking only to inner data, from the emphasis on filtering efficiency to low resistance requirements, from initial data looking only to the load test requirement. However, top melt blown fabric manufacturers will pay more attention on the following four points.

1. The efficiency margin should be enough with the same grade filter material.

2. Lower resistance with the same filtration efficiency.

3. The persistence of filter efficiency and load-resistant properties.
      4. Material uniformity.
