Since the outbreak of COVID-19, disposable mask filter materials that can effectively intercept respiratory droplets and tiny airborne particles carrying pathogens have become an important material for making masks. Let’s take a look at the details.
Polypropylene resin is one of the four general-purpose thermoplastic resins (polyethylene, polyvinyl chloride, polypropylene, polystyrene). It is produced through polymerization reaction with propylene as raw material and ethylene as comonomer.
The process methods for producing polypropylene include the following categories: solvent method, solution method, liquid phase bulk method (including liquid phase and gas phase combined method) and gas phase method.
The filter material of disposable masks can filter more than 95% of bacteria and PM2.5 particles in the air, reaching the filtration standard of KN95 masks.
The extremely high porosity and ultra-thin thickness of <5μm give it better air permeability, low breathing resistance and comfortable wearing.
In addition, the PTFE membrane is naturally hydrophobic, and the filtration mechanism is physical and mechanical interception (pore size interception method). The interception rate will not be attenuated due to moisture in the exhaled breath. Compared with ordinary melt-blown cloth masks, the protective effect of electrostatic adsorption is more stable and lasting.
It is a manufacturer of disposable mask filter materials that specializes in R&D, production and sales.
The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability.
It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
The company has a full set of advanced production equipment and testing instruments, as well as a complete pre-sales, sales and after-sales service system.
