What Are The Processing And Production Processes Of Pe Breathable Film?

The waterproof and breathable raw material used in PE breathable film is a new type of waterproof material widely used in modern industry and construction. From the name, we know that it has two basic functions of waterproof and breathable. The raw material of waterproof and breathable film is mainly made of PP spinning. Sticky non-woven fabric, PE polymer breathable membrane, PP spunbonded non-woven fabric are composed of three materials. Maybe you don’t understand the processing technology of waterproof and breathable membrane. The waterproof and breathable membrane processing manufacturers will introduce the raw materials of waterproof and breathable membrane for you. Production process:

There are three main production processes for waterproof and breathable membranes:

1. Cast compounding. This kind of processing technology is to rely on the viscosity of the plastic itself to compound after hot-melting plastic particles. In fact, this is a very common non-woven fabric coating. The disadvantage is that it is hardly breathable. There is no highly breathable waterproof breathable membrane produced by this process at present.

2. Glue spraying or squeegee compounding (hot melt compounding). This process was first applied to sanitary napkins, diapers, and protective clothing. At present, some manufacturers are still using this process to produce highly breathable waterproof and breathable materials. Since this glue is actually a pressure-sensitive adhesive itself, this waterproof and breathable membrane can only be a shrunken version of the real waterproof and breathable membrane, and the glue will be opened soon after being placed for a period of time.

3. Hot pressing compound. At present, there are many manufacturers using this technology, and the application is becoming more and more mature, which has well realized the high air permeability, high temperature resistance, anti-aging and other properties of the waterproof and breathable membrane.

The processing and production process of waterproof and breathable membrane is mainly the above three processing methods. With the advancement of science and technology and the deepening of material research, there must be some new processing methods of waterproof and breathable membrane developed and gradually matured. The raw materials of waterproof and breathable membrane have The performance and advantages that some other waterproof materials do not have. While the waterproof and breathable membrane is air-tight and water-tight, the waterproof and breathable membrane material has good air permeability, which can make the water vapor inside the electronic product or equipment well discharged, thereby So that the internal components of electronic products will not be damaged by water and other liquids, and at the same time, it can save costs or budgets to a certain extent, and solve the waterproof, breathable, and sound-permeable problems while also balancing the atmospheric pressure difference inside and outside.
