What production process does Waterproof vent have?

Waterproof vent is a relatively common product in the field of waterproofing and ventilation. It is mainly a waterproof tool made of some polymer materials. This tool not only has good waterproof properties, but also has very good air permeability and airtightness. , especially those products with guaranteed quality, have greater efficacy in the performance of these two aspects. In fact, when we choose a Waterproof vent, we must understand how these products are produced and processed. The real high-quality products are often produced with polymer waterproof materials. These materials can use hot-pressing composite production technology. The products made by using this method not only have good waterproof performance, but also have high air permeability, high temperature resistance and high pressure resistance. Using these products, it can even be used at a net water pressure of about three centimeters. normal work. Because the production process of hot pressure load will repeatedly use high temperature and high pressure for compound treatment, so no glue will be used in the production process, which also fully guarantees the air permeability and water resistance of the product and prolongs the life of the product.
