EVAL™ enables to produce lighter fuel tanks with very low evaporative emissions.
As environmental policies continue to evolve, several efforts have been made to improve the air quality by limiting pollution from all sources.
European emission regulations for light duty vehicles were formerly specified in Directive 70/220/EEC. This Directive was repealed and replaced by regulation 715/2007 (EURO 5/6).

In the US, emission regulations for gasoline fuel tanks are created on the federal level by the Environmental Protection Agency (EPA) and on the state level by the California Air Resource Board (CARB). The chart below summarizes the vehicle emission maximums that have been in place over the last 20 years from both the EPA and CARB.
EVAL™ EVOH products are commercially used in multilayer plastic fuel tanks, lines and filler pipes. Over 250 million cars have been produce to date using EVAL™ with no known fuel systems failures related to the EVAL™ product.
