Polyolefin encapsulation materials (referred to as encapsulant films) are the core auxiliary materials of photovoltaic modules

Concept: Photovoltaic encapsulant film mainly refers to the photovoltaic encapsulation material made of EVA resin (or POE resin) by adding suitable crosslinkers, anti-aging agents, coupling agents and other additives, after melt extrusion, using calendering or casting.

Application: Encapsulant film is applied to the lamination link of photovoltaic module packaging, covering the upper and lower sides of the cell, and the upper glass, the lower backplane (or glass) are integrated by vacuum lamination technology to form a component. Thickness between 400um -600um

Function: As the core material of photovoltaic modules, encapsulant film plays a protective role on the cells, so that photovoltaic modules are not affected by external environmental influences during operation, prolong the service life of photovoltaic modules, and maximize the sunlight through the film to reach the cells, improving the power generation efficiency of photovoltaic modules.

Performance: Its quality (performance indicators such as light transmittance, shrinkage, peel strength, aging resistance, etc.) is critical to achieving a 25-year service life of the component.
