Typical usage ratio

• 60–80% by weight in foam soles and midsoles, adjusted for hardness and rebound as required by end user segment (casual, athletic, or industrial safety shoes)

Downstream process integration

• Molders meter EVA resin into compounding units with blowing agents, crosslinkers, and colorants, feeding the blend into injection presses where foaming and shaping occur under controlled temperature and pressure.

Final product types

• Running shoe midsoles and outsoles
• Protective work boot soles
• Beach sandal and flip-flop bases
• Orthopedic and anti-fatigue insoles

5. Solar Panel Encapsulant Sheets

Encapsulant sheet producers use this EVA to create the vital protective interlayer in photovoltaic (PV) modules, leveraging its transparency, adhesive, and crosslinking properties. It safeguards silicon solar cells against moisture ingress, thermal cycling, and UV degradation while ensuring long service life under outdoor exposure conditions.

Industry compliance standards

• IEC 61215 (PV module performance qualification)
• UL 1703 (Flat-plate PV modules and panels)
