Definition
1. EVA is an encapsulant used between the glass cover and the solar cells in PV modules. It is durable, transparent, resistant to corrosion, and flame retardant.
2. Ethylene vinyl acetate is the copolymer of ethylene and vinyl acetate. It’s an extremely elastic material that can be sintered to form a porous material similar to rubber, yet with excellent toughness. The porous elastomeric material is three times as flexible as low-density polyethylene (LDPE), showing tensile elongation of 750% with a peak melting temperature of 250°F (96°C).
