Ethylene-vinyl acetate copolymer(Cas 24937-78-8) Usage
|
Description |
Ethylene-vinyl acetate (EVA), also known as poly(ethylene-vinyl acetate) (PEVA), is a copolymer consisting of ethylene and vinyl acetate monomers. The proportion of vinyl acetate typically ranges from 10% to 50%, with ethylene comprising the remainder of the polymer. |
|
Physical properties |
Ethylene vinyl acetate is available as white waxy solids in pellet or powder form. Films are translucent. |
|
Uses |
EVA is widely utilized in the footwear industry for its lightweight nature and excellent foamability performance. It is commonly found in athletic shoes, sandals, and other recreational footwear due to its cushioning and shock-absorbing properties. Additionally, EVA is used in sports equipment, such as padding for helmets and protective gear, and in leisure products like pool floats and yoga mats. EVA is utilized worldwide for the encapsulation of photovoltaic (PV) modules in solar panel applications. Its properties, such as high electrical resistivity, low processing and cross-linking temperatures, low water absorption ratio, and good optical transmission, make it an excellent material for encapsulating solar cells. EVA encapsulation helps protect PV modules from environmental factors while allowing efficient light transmission for energy conversion. |
