Product Description:
The key functional material of the ePTFE microfiltration membrane plane protection masks is the polytetrafluoroethylene composite filter material, which uses the principle of physical barrier to protect all kinds of particles (such as dust, smoke, mist and microorganisms).
The masks materials are mainly composed of outer non-woven fabric or woven fabric, middle polytetrafluoroethylene composite filter material, inner skin-friendly non-woven fabric or woven fabric.

Executive Standard: GB2626-2006
Product Category and Level: Disposable Masks
Ingredients: Waterproof non-woven fabric, special ePTFE composite filter material, skin-friendly woven or non-woven fabric, non-latex elastic band, nose bridge strip.
Filter Material: It is a composite of special expanded polytetrafluoroethylene (ePTFE) microporous membrane and non-woven fabric. ePTFE microporous membrane has the characteristics of high efficiency filtration, waterproof, moisture permeability and so on. It can effectively achieve the good effect of breathable and watertight, filtering PM2.5, resisting microorganisms and bacteria, and it will not fail due to moisture.

Activated Carbon Masks

Acutal Measured Datas of ePTFE Protective Masks

According to the testing report issued on Mar. 02nd, 2020, its performance indicators especially Filtration Efficiency meet the requirements of China Standard GB 2626-2006 KN95.

Based on the principle of electrostatic adsorption, as the use time increases or the temperature and humidity change, the filtration efficiency of ordinary N95 masks decreases significantly. The operating conditions of ordinary disposable masks are single, the breathing resistance is high when the filtering efficiency is high, and it is easily affected by environmental factors such as temperature and humidity. It is a one-time use and a large waste of resources.

Based on the principle of physical barrier, ePTFE protective masks are not sensitive to the effects of water, temperature and humidity, and can withstand sterilization methods such as boiling water, alcohol, 84 disinfectant, etc. If worn properly without damage, it can be used again after disinfection. The ePTFE microfiltration membrane flat protective mask can cope with a variety of working conditions, high filtration efficiency, low breathing resistance, good wearing comfort, good safety and long service life.

Not Afraid of Water and Disinfectant, Just Because of Having High-Tech "Core"
----Reveal of High-Efficiency Filtering Long-Life Protective Mask

The ePTFE microporous membrane masks made of non-perfluorooctanoic acid (PFOA) PTFE resin have been tested by the national authority, and the filtration efficiency has reached 99.2% (N95, KN95 masks level). The inhalation resistance is less than 15% of the standard limit, which can effectively achieve a good effect of impermeable to water, filtering PM2.5, and preventing microorganisms and bacteria from entering the body.

The ePTFE microporous membrane is a kind of microporous film formed by polytetrafluoroethylene (PTFE) resin after being expanded and stretched. After microscopic observation and testing, its micropores are uniformly distributed and the pore diameter is about 100 times smaller than that of meltblown cloth, with a porosity as high as 80% or more, while having good air permeability, it has excellent filtration efficiency. PTFE is a material that can be used in biomedicine, artificial blood vessels, etc., and has no biological toxicity. PTFE that does not use PFOS in the production process is a new generation of environmentally friendly products, which is safer for use on masks. At present, most protective masks using meltblown non-woven fabrics on the market. The mechanism for filtering PM2.5 and viruses is electrostatic adsorption, which fails after washing and has a short service life. The principle of expanded PTFE microporous membrane filtration is physical barrier, which has the characteristics of high efficiency filtration, breathability, windproof, etc. PTFE microfiltration membrane masks can block dusts on the surface of the masks, and can also filter oily particles, such as automobile exhaust, kitchen fume, etc. Expanded PTFE microporous membrane as a newcomer of masks filter material is also the future development direction. It has more excellent comprehensive performance and longer service life than traditional meltblown non-woven fabrics.

The ePTFE microporous membrane protective masks, which looks like a "disposable medical masks", actually has a highly efficient filtering "core" between the two thin layers of non-woven fabric, which is breathable, dustproof and filtering bacteria, and can withstand boiling water, alcohol, 84 disinfectant and other disinfection and sterilization methods. In the case of a shortage of masks, if the mask is normally worn without damage, it can be used again after disinfection.
