• Improved adhesive: The PV modules’ long-term durability and dependability are guaranteed by the silane grafting process, which strengthens the adhesive between the EVA film and other components like encapsulants or substrates.
• Crosslinking Efficiency: By encouraging effective crosslinking of the EVA matrix, these additives enhance the material’s mechanical strength, resistance to environmental influences, and dimensional stability. 
• Crosslinking Efficiency: By encouraging effective crosslinking of the EVA matrix, these additives enhance the material’s mechanical strength, resistance to environmental influences, and dimensional stability. 
• UV Resistance: Silane grafted additives provide exceptional UV resistance, reducing the possibility that the EVA film would yellow, discolor, or degrade after extended exposure to sunlight.
• Moisture Barrier: By improving the EVA film’s moisture barrier qualities, the additives lower the chance of moisture intrusion and possible PV module performance deterioration.

Better Power Conversion Efficiency: These additives’ improved adhesion and crosslinking efficiency lead to better power conversion efficiency, which raises the amount of electricity produced.

Extended Durability and Longevity: The PV modules’ resilience to UV rays, enhanced adhesion, and moisture barrier qualities contribute to their extended durability and longevity, guaranteeing dependable performance throughout their operational lives.

Increased Mechanical Strength: Silane-grafted EVA additives strengthen the EVA film’s mechanical strength, lowering the possibility of module breakage and boosting resistance to mechanical stress during setup or use.
