(Summary description)What is PFE99 Melt-blown Fabric? PFE99 Melt-blown Fabric refers to a melt blown fabric with a filtration level of 99%. The filtration efficiency here generally refers to a particle detection of 99%, which is PFE detection. Let's simply say that this PFE test is like passing air containing tiny particles through a melt blown cloth.

What is PFE99 Melt-blown Fabric? PFE99 Melt-blown Fabric refers to a melt blown fabric with a filtration level of 99%. The filtration efficiency here generally refers to a particle detection of 99%, which is PFE detection. Let's simply say that this PFE test is like passing air containing tiny particles through a melt blown cloth.

PFE99 Melt-blown Fabric

The degree of completion that the meltblown cloth can intercept, 100% of the particles is the best, the particles can not pass through, such a meltblown cloth can play a very good role as the filter layer of the mask, but it is impossible to achieve 100% , The current grade 99 PFE99 Melt-blown Fabric is the highest standard. But this standard is also very high.

For example, for our medical surgical masks, the filtration requirement for PFE particles is not less than 30%. Many people are surprised. No, this is too dangerous. Most of them are not filtered out. Doesn't it provide protection after breathing?

This is about a meltblown cloth and another test item, the bacterial filtration test, that is, the BFE test. The working environment of medical surgical masks is mainly to filter viruses, bacteria, etc., and there are basically no particulate harmful substances in the air. , The BFE filtration required by medical surgical masks should not be less than 95%. That is to say, the filtration efficiency of melt blown cloth should also be divided into filtering objects, but we usually call 90.95.99 to describe melt blown cloth, generally it is Refers to PFE99, which is the filtering effect of particle detection.
