The manufacturing process of ptfe waterproof and breathable membrane can be simply understood as follows: first, the monomer tetrafluoroethylene is polymerized to form the polymer polytetrafluoroethylene, and then the ptfe is made into porous waterproof and breathable membranes with different pore sizes through processes such as stretching. Material.
The main functions of waterproof and breathable fabrics are: waterproof, moisture-permeable, breathable, insulating, windproof, and warm.
The moisture permeability is 16,000g per square meter per 24 hours, the waterproof pressure can reach 8,000-20,000mm water column, and the insulation can reach up to 100,000 volts.
This fabric can maintain its antimicrobial effect in harsh environments and can adapt to temperatures ranging from 427 degrees to minus 200 degrees.
In terms of production technology, the technical requirements of waterproof and breathable fabrics are much higher than those of ordinary waterproof fabrics; the pore size of ptfe waterproof breathable membrane ranges from 0.02um to 0.2um, and the porosity reaches more than 88%.
In the state of water vapor, the water particles are very small, and these water particles can penetrate all the way down the capillary to the other side, causing vapor permeability.
If water vapor condenses into water droplets, the particles will become larger, and the surface tension of the water droplets will act, and the water molecules will not be able to smoothly leave the water droplets, penetrate and reach the other side. In other words, this process This can prevent water penetration, allowing the waterproof and breathable membrane to truly have a waterproof function.
It is a high-tech enterprise specializing in the research and development, production and sales of ptfe waterproof and breathable membranes. It has a factory area of nearly 4,000 square meters and professional production equipment. It is a partner of the top 500 companies in the United States; we produce The products are produced using imported raw materials, with finer molecular weight, cleaner quality and better uniformity.
