Typical usage ratio

• Film thickness typically 400–650 μm, accounting for 15%–20% of total module weight; ratio finely adjusted for float-glass vs. thin-film module design.

Downstream process integration

• Pellet feeding to dedicated extruder lines; flat-die or calendering film extrusion; film lamination in vacuum module press with crosslinking under heat; cutting and assembly with glass and backsheet layers.

Final product types

• Photovoltaic solar panels for grid-connected plants
• Building-integrated PV modules
• Flexible thin-film solar laminates
• Portable solar charging modules

4. Wire and Cable Insulation Compounds

Wire and cable manufacturers incorporate this EVA in compounds for low voltage power and data cable jackets and insulation. The material is compatible with inorganic flame retardants, meeting regulatory safety while maintaining reliable processability during extrusion and pelletizing. This supports stringent quality control on dielectric strength and exterior mechanical properties.

Industry compliance standards

• IEC 60502-1 (Power cables with extruded insulation)
• UL 62 (Flexible cords and cables)
• GB/T 2951 (Electrical cable insulation testing standards)
• REACH and RoHS hazardous substance limits

• 40%–70% EVA content in the cable insulation/filler compound; ratio tailored to compound formulation and required flame retardancy, altered by inclusion of ATH (aluminum trihydrate) and processing aid.

Downstream process integration

• Compounding with flame retardant minerals in high-intensity mixers; melt feeding into twin screw extruder; application as primary insulation or outer jacket layer over copper/aluminum cores; pelletizing for storage or direct cable extrusion.

Final product types

• Low voltage indoor power cables
• Flexible appliance cords
• Data and telecom insulation sheathing
• Instrumentation cable jackets

5. Waterproofing and Construction Membranes

Construction materials factories utilize this EVA resin to modify bituminous or polymer-based waterproofing membranes. Its specific melt point and flexibility enhance membrane elongation, tear resistance, and environmental durability for demanding roofing, tunnel lining, and foundation sealing projects.
