POE film and EVA film are two common material films, which have some differences in performance, application fields, and preparation process. Although POE film and EVA film have similarities in some aspects, due to their different chemical structures and properties, POE film production lines are usually not directly used to produce EVA film.
Secondly, there are also differences in the melting point and temperature between POE and EVA. POE has a lower melting point and higher melting temperature, while EVA has a higher melting point and lower melting temperature. This means that during the production process, the POE film production line needs to have high temperature control capabilities to ensure that the POE material can fully melt and flow. The EVA film production line needs to have lower temperature control capabilities to avoid overheating and decomposition of EVA materials.
In addition, POE and EVA also differ in terms of flexibility and cold resistance. POE has good flexibility and cold resistance, and can maintain a certain degree of softness and toughness even at low temperatures. However, EVA has relatively poor flexibility and cold resistance, making it prone to brittleness and unsuitable for use in low-temperature environments. Therefore, the process parameters and equipment design of the POE adhesive film production line need to take into account the characteristics of POE materials, while the EVA adhesive film production line needs to make corresponding adjustments based on the characteristics of EVA materials.
In addition, there are also differences in the preparation processes of POE and EVA. POE films are usually prepared by extrusion or injection molding, and the preparation process is relatively simple. EVA, on the other hand, is usually prepared by complex processes such as hot melt rolling or hot melt lamination, resulting in a relatively complex preparation process. Therefore, the equipment and process parameters of the POE adhesive film production line may not be suitable for the preparation of EVA adhesive film.
In summary, although POE film and EVA film have similarities in some aspects, due to differences in their chemical structure, melting point and temperature, flexibility, and cold resistance, POE film production lines are usually not directly used to produce EVA film. If it is necessary to produce EVA film, it is recommended to choose a dedicated EVA film production line to ensure product quality and production efficiency.
