【Frontiers in HaiChuan Chemical Technology】Brazil develops and commercially produces sucrose-based ethylene-vinyl acetate copolymer (EVA) using sucrose as a raw material
Thread Content
Recently, Braskem of Brazil announced that its newly developed sugarcane-based ethylene-vinyl acetate copolymer (EVA) grade, “I’m green EVA 7870S”, has been put into commercial production. Made from 100% sugarcane ethanol, this product has a carbon footprint 65% lower than that of traditional petroleum-based EVA, making it the world’s first photovoltaic-grade bio-based EVA material to obtain ISCC PLUS certification. According to the information provided, the “I’m green EVA 7870S” has a bio-based carbon content of 70%; each ton of this product helps reduce 3 tons of carbon dioxide emissions, which is equivalent to the carbon-sequestration capacity of 160 mature trees. While enabling a low-carbon transformation across the entire life cycle, this bio-based EVA material retains the excellent optical properties and resistance to heat and moisture aging of traditional EVA. The photovoltaic encapsulation films made from it have a light transmittance of >91.5%, and they exhibit minimal power degradation even after being subjected to heat and moisture aging tests for over 3000 hours
How widely is this technology used in South China?

During this year, a steady supply of sugarcane must grow in the fields, and weather conditions must be favorable – neither drought nor excessive flooding should occur.
