At present, PTFE bubble film plays a decisive role in the national economic fields such as chemical industry, machinery, electronics, electrical appliances, military industry, clothing, and environmental protection.
In the electronic field, a special process is used to appropriately adjust the microporous structure of the PTFE film so that it can form an adsorption and storage function for static electricity on the basis of heat dissipation, so that it can preserve the static electricity generated during the use of precision electronic products. This effectively avoids interference and damage to electronic products due to their own static electricity problems.
In the chemical industry, polytetrafluoroethylene bubble point film is made of polytetrafluoroethylene and is expanded and stretched to form a microporous film. This film is coated on various fabrics and fabrics using a special process. On the base material, it becomes a new filter material.
The membrane has a small pore size, about 0.2-0.5μm, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria, achieving advanced purification and ventilation purposes.
In the field of clothing, the diameter of polytetrafluoroethylene bubble-point membranes varies from 0.1 to 0.5 microns, while the diameter of water vapor molecules is 0.0004 microns. The diameter of the smallest mist in rainwater is 20 microns, the diameter of drizzle is already as high as 400 microns, the pore diameter is between water vapor and rainwater, the micropore diameter is smaller than the smallest light mist among water molecules, and much larger than the diameter of water vapor molecules, allowing water vapor to pass through but water droplets cannot. This microporous structure can be used to achieve excellent waterproof and breathable functions, so it is an excellent waterproof and breathable material.
