EVOH (Ethylene Vinyl Alcohol) resins have garnered widespread application in the automotive industry, particularly in the realm of fuel systems, due to their superior barrier properties. The ability of EVOH to minimize the permeation of gasoline vapors plays a crucial role in both environmental protection and vehicle safety, marking it as an essential material in modern automotive design.
In automotive manufacturing, EVOH is predominantly used in the construction of fuel tanks and fuel lines. Functioning as an inner layer within multilayer systems, EVOH effectively deters the permeation of hydrocarbons, thus preventing fuel evaporation. A notable example involves a leading automobile manufacturer who embraced EVOH technology to meet stringent emissions regulations. By incorporating EVOH into their fuel systems, the manufacturer achieved a significant reduction in fuel vapor emissions, effectively meeting environmental standards and lowering the overall environmental footprint of their vehicles.
