1. Introduction of EVA/POE solar film extrusion line
(1) Special EVA encapsulating film for solar modules (photovoltaic modules) and related solar products is used to encapsulate solar panels, which is non-sticky at room temperature and easy to operate. After hot pressing, thermal cross-linking will occur due to chemical and bonding enhancement reaction to produce a permanent adhesive seal. Product features: high light transmittance/high adhesion strength/high light and heat stability/superior volumetric electricity group rate.
 
(2) Compared with EVA film extrusion line, the biggest advantage of POE film extrusion line is low water vapor transmission rate and high volume resistivity, which ensures the safety and long-term aging resistance of the module in high temperature and high humidity environment, and ensures long-term use of components. Specifically, the superior performance of the POE film relative to the EVA film is that the POE film is a copolymer of ethylene and octene, is a saturated fatty chain structure, and has fewer tertiary carbon atoms in the molecular chain, showing good weather resistance, UV aging resistance, excellent heat resistance and low temperature resistance, so POE film extrusion line has better aging resistance than EVA film. Through modification methods such as photo-grafting polar monomer, plasma surface treatment or reactive grafting modification to POE, it can improve the adhesion of POE film extrusion line and glass, backplate and other materials, and has excellent interfacial adhesion performance.
 
(3) It is suitable for high-efficiency double-sided batteries, which can effectively enhance the conversion efficiency of the battery. Compared with ordinary single-sided power generation modules, it increases the power generation rate and reduces the cost of electricity. At the same time, the modules can be placed vertically and have more utilization methods. The POE film has a lower water vapor transmission rate and greater cohesion. It is more suitable for double-glass modules, so that the produced double-glass modules do not require edge sealing and have a longer service life.
 
2. Features of EVA solar film extrusion line
(1) High transparency and high adhesion can be applied to various interfaces and used for bonding glass and silicon wafers.
(2) Good durability can resist high temperature, moisture, ultraviolet rays and so on.
(3) Easy to store. Stored at room temperature, the adhesion of EVA is not affected by humidity and water-absorbent film.
 
3. Characteristics of POE polyolefin extrusion line
(1) POE has the general characteristics of thermoplastic elastomers. The soft chain curling structure of octene and the crystalline vinyl chain are used as physical crosslinking points, making it both excellent toughness and good processability;
(2)The price is low and the relative density is small, so the volume and price are low;
(3) Excellent heat resistance and cold resistance, and a wide using temperature range;
(4) Weather resistance, good aging resistance, because there are no unsaturated double bonds in the molecular structure of POE plastics, it has excellent aging resistance;
(5) Oil resistance, compression permanent deformation and abrasion resistance are not good;
(6) POE plastics have narrow molecular amount distribution, good fluidity, and good compatibility with polyolefins;
(7) Good fluidity can improve the dispersing effect of the filler and at the same time increase the weld line strength of the product.
