In the production process, the breathable film needs to be sprayed or scraped with hot-melt pressure-sensitive adhesive;
It has outstanding heat-resistant stability, good low tenderness, high initial adhesion and good adhesion retention. It is suitable for breathable membranes.
Characteristic
Hot melt pressure-sensitive adhesive is sprayed or scraped. This process was first used in sanitary napkins, diapers and protective clothing.
At present, almost all manufacturers use this process to produce waterproof and breathable materials with high permeability.
During the production process, attention shall be paid to prevent the micropores of the breathable membrane from being blocked by hot melt adhesive, resulting in the reduction of the air permeability.
Application
Because of its microporosity, hydrophobicity and hydrophobicity, it has the function of air permeability, water resistance and oil resistance;
It has been widely used in medical treatment, precision electronics, automotive lamps, communications, chemical industry, security and other industries.
