Research shows that the filtration mechanism of ffp2 mask filter material is purely physical filtration, and the long-term storage efficiency will not be reduced, which is safe and reliable. In addition, the filtration efficiency will not be reduced after boiling water cooking and alcohol disinfection and sterilization, which can be achieved reuse.
FFP2 is the EU standard. EU masks are divided into two categories: personal protective masks and medical masks.
The European standard for personal protective masks is EN149. According to the standard, masks are divided into three categories: FFP1/FFP2/FFP3: FFP1 protective masks, the filtration efficiency of oily and non-oily particles is required to be no less than 80%, this filtration efficiency is slightly lower , not suitable for use under the current epidemic situation.
ffp2 mask filter material is a polymer waterproof material.
From a production point of view, the technical requirements of waterproof and breathable membranes are much higher than those of ordinary waterproof materials. From a quality point of view, it also has functional characteristics that other waterproof materials do not have.
The porosity of the film can reach more than 85%, and the air can flow smoothly.
The membrane pore size is 0.2-3μm, which can effectively isolate water points, and the waterproof grade can reach IPX7 or above.
Protect electronic instruments from becoming unusable due to moisture or water.
PTFE film manufacturer specializes in the production of FFP2 mask filter materials. It has a full set of advanced production equipment and technology. It also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of PTFE film; the product materials produced are all Using imported raw materials, it has high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
