Ethylene Vinyl alcohol copolymer (EVOH)
EVASIN, ethylene vinyl alcohol copolymer (EVOH) is an extrudable plastic barrier material with excellent barrier properties for oxygen and a variety of other gases and volatile products (flavor barrier).
Chang Chun Petrochemicals (CCP) has developed high performance EVOH grades for new applications in food packaging and agricultural sectors among others.
EVOH copolymer also has excellent chemical and oil resistance that enable it to be used as the fuel barrier layer in low emission fuel tanks for automotives.
EVASIN is the trade name of ethylene-vinyl alcohol copolymer (EVOH), developed by Chang Chun Petrochemicals.
EVOH copolymers are composed of ethylene and vinyl alcohol. With the support of Arkema knowledge as a tie layer producer, new grades are being developed by Chang Chun Petrochemicals that combine gas barrier properties, oil resistance, transparency, and outstanding processability.
As a distributor representing CCP in Europe, Africa and Middle-East, Arkema offers a range of EVOH containing between 29% and 44% of ethylene.
With their excellent gas barrier properties, EVASIN can be combined to OREVAC® grafted polyolefins to be used as internal layer of multilayer structures in packaging and industrial applications. EVASIN copolymers also preserve flavors and aromas.
