Application Areas

Construction Industry

  1. Photovoltaic Module Encapsulation: EVA film is a key encapsulation material for photovoltaic modules. Located on the top and bottom sides of the solar cell, it ensures a strong bond between the cell and the glass and backsheet. Its presence also improves the module’s durability and photoelectric conversion efficiency.
  2. Double-Layer Glass Panel Modules: EVA film is used to bond double-sided glass, meeting the high transparency and aging resistance requirements of double-layer glass photovoltaic modules during use. It also meets the UV protection requirements of laminated glass, thus being widely used in high-rise building curtain walls, safety glass, soundproof glass, etc.
  3. Agricultural Photovoltaic Greenhouses: Used for encapsulating photovoltaic greenhouse modules, ensuring the film’s transparency to maximize light energy utilization while improving moisture and mildew resistance.
  4. Safety Glass: EVA film is used in security scenarios such as banks, monitoring rooms, and explosion-proof glass, providing impact protection and optical clarity.

Automotive Industry

  1. Automotive Laminated Glass: EVA film is widely used in the lamination of automotive windshields and sunroofs due to its high transparency, impact resistance, and sound insulation properties.
  2. Automotive Photovoltaic Applications: Provides efficient encapsulation materials for automotive rooftop solar panels.

Electronics Industry

  1. Electronic Screen Protector: EVA film is used to produce display screen protectors, offering excellent optical transparency and durability.
  2. Touchscreen Encapsulation: Used for encapsulating touchscreens and electronic devices to protect components and extend their lifespan.
  3. Optical Film: Used to manufacture high-transparency, low-haze optical films suitable for high-end electronic devices and precision instruments.

Arts and Medical Industry

  1. Art Glass: The excellent optical properties of EVA film are often used to produce colored laminated glass or decorative art glass to achieve special visual effects.
  2. Medical Packaging: Due to its high transparency and non-toxic, environmentally friendly properties, EVA film is often used in the packaging of medical devices or pharmaceuticals.
