Orevac® resins are polyolefins (PE, PP, or EVA) modified with maleic anhydride.
Due to their reactivity, they are used in multiple applications such as multilayer packaging, pipe coating, coupling agents, etc. Thanks to their adhesive power, Orevac® grafted polymers are used as tie layer in the production of multilayer barrier films. They can also be used as coupling agents in PP and HFFR compounds to improve mechanical properties of filled polyolefins compounds. Orevac® grafted polyolefins give excellent bonding strengh to EVOH barrier resins especially Evasin ethylene vinyl alcohol copolymers.
Arkema offers both ready to use Orevac® thermoplastic adhesives and concentrates for dilution by customers.
