What is the difference between standard-cure and fast-cure types?

Guangzhou Zanchen New Material Technology Co., Ltd.


The main differences between Standard Cure and Rapid Cure EVA films are crosslinking speed and productivity. The following are the specific differences between these two types of EVA films:

Cross-linking speed: Rapid-cure EVA films are particularly well suited for high-speed production lines, as they allow the cross-linking process to be completed in a short period of time, thereby increasing productivity. In contrast, standard-cure EVA films are slower and take longer to complete the cross-linking process.

Productivity: Because fast-curing EVA films are able to cross-link in a short period of time, they are often better suited for large-scale industrial production, especially for applications that require high throughput. Standard cure EVA films, on the other hand, may be better suited for small or medium scale production, as their cross-linking speed does not affect the overall production schedule.

In summary, the choice between standard-cure and fast-cure EVA films depends on production requirements and the specific application.

What is the crosslinking process of EVA film?

Crosslinking agent addition: The degree of crosslinking can be controlled by adjusting the amount of crosslinking agent added. If too much cross-linking agent is added, although the cross-linking degree will be increased, it will easily lead to aging and yellowing of the material; on the contrary, if too little cross-linking agent is added and the cross-linking degree is too low, it will affect the bonding strength and aging resistance.

Peroxide cross-linking: This is a traditional chemical cross-linking method, which generates free radicals through high temperature decomposition of peroxides, triggering a series of free radical reactions to form a cross-linking network in polyolefin materials. This process can be expressed by the following chemical reaction equation: ROOR → 2RO-, PH + RO- → P- + ROH, P- + P- → P-P.

Silane cross-linking technique: This method is commonly used for polyethylene and consists of two processes: grafting and cross-linking. Silicone compounds containing unsaturated vinyl and easily hydrolyzable alkoxy polyfunctional groups are first grafted or copolymerized onto the main chain of polyethylene, then mixed with additives for molding, and finally hydrolysis and condensation reactions are carried out in the presence of water and catalysts.

To summarize, the cross-linking process of EVA film is a complex chemical process, which requires precise control of the amount of cross-linking agent added and the reaction conditions to ensure that the performance of the final product meets the requirements of the photovoltaic module.
