introduction to eva film categories

introduction to eva film categories:

1. eva glass intermediate adhesive film: eva adhesive film is a sticky thermosetting adhesive film, generally used in the middle of laminated glass (eva is the abbreviation of ethylene vinyl vinyl acetate acetate). the national standard "gb9962-99" allows the use of eva film for laminated glass.

eva glass film is one of the main materials for making safety laminated glass and strengthened photographic glass. whether qualified laminated glass and strengthened photographic glass products can be successfully produced depends on the equipment (laminated furnace or tempered furnace) and production process. , glass and accessories, laminated decorative materials, environmental climate conditions, employees' operating skills and work responsibility, etc. are closely related to many factors. the quality of the film is only one of the restricting factors. therefore, when making safety laminated glass and strengthened photo glass, comprehensive factors should be analyzed and comprehensive production skills should be mastered.

2. eva solar cell adhesive film: this eva adhesive film is non-sticky at room temperature and is generally used in solar cell packaging. this operation is simple and convenient. the eva adhesive film undergoes bonding strengthening changes under hot pressing, and the adhesive seal produced during this process is permanent.

as the core material of photovoltaic modules, the encapsulation film protects the cells and allows sunlight to reach the cells through the film to the maximum extent, thereby improving the power generation efficiency of the photovoltaic modules. the photovoltaic encapsulation film needs to ensure that the solar modules have a service life of 25 years.
