Applications of BASF-YPC V3610F EVA in Industrial Manufacturing

As the original manufacturer of BASF-YPC V3610F EVA, we supply this material for critical industrial applications where precise compounding, quality control, and traceability are mandatory. Below are detailed application scenarios based on established industry practice and compliance frameworks.

1. Solar Photovoltaic Encapsulant Film Manufacturing

V3610F EVA is widely selected by module producers for encapsulant film due to its melt flow properties and crosslinking response. Manufacturers use it to achieve strong adhesion to both backsheet and glass, low water vapor transmission rates, and high optical transmittance in the final encapsulation layer. The formulation and extrusion parameters are strictly managed to meet PV module durability and certification requirements, with crosslinking agents and anti-aging additives dosed as per cell technology and regional climate conditions.
