Did you know? Compared with some ordinary masks, masks made of polytetrafluoroethylene mask film have more outstanding performance and effect. The editor below will take you to learn about this material.
The polytetrafluoroethylene mask film is generally made of polytetrafluoroethylene (ptfe) suspended powder, which is expanded and stretched to form a microporous film.
Bubble point film has a fibrillar microporous structure with a porosity of more than 88%, 1.4 billion micropores per square centimeter, and a pore size range of 0.1μm-0.5μm. This film is coated on various fabrics using a special process and base material, it can become a new type of filter material.
It is a ptfe environmentally friendly filter material manufacturer that specializes in R&D, customization, production and sales.
Our company can customize according to user’s requirements.
The optimized combination of key technical parameters such as speed ratio, pressure ratio, operating temperature, etc. can realize online control of air permeability, thickness and void ratio according to the ratio and pore-forming medium to meet the different requirements you need. .
The polytetrafluoroethylene mask membrane has a three-dimensional mesh structure with no through holes.
The porosity and pore size distribution are important indicators for measuring films.
The porosity of the film is generally between 80% and 95%. A high porosity will increase the ventilation; the pore size distribution is concentrated, indicating that the membrane pore size is uniform.
With special production technology, different pore sizes can be controlled for different materials to achieve high-efficiency filtration.
In addition to masks, film materials have broad application prospects. In the future, they will also be dedicated to a series of specific military and police fire protective clothing, artificial skin dressings, artificial blood vessels, fuel cell ion exchange membranes, membranes for outdoor tents, and building ceilings.
