lotader®4503

ethylene acrylic acid copolymer

arkema

产品说明：

lotader® 4503 is a random terpolymer of ethylene, acrylic esterand maleic anhydride, polymerized by high-pressure autoclaveprocess.
applications
lotader® 4503 is a versatile adhesive for extrusion lamination,designed as a ready for use resin to be used pure.
lotader® 4503 gives excellent adhesion to plain, primer-less opetfilms as well as to other plastic films like opp, cpp, opa andreverse-printed films. it also bonds to easier substrates like pefilms, aluminium foil, metalized plastics, paper and board.
typical uses are:

adhesive for extrusion lamination of polar and non-polar filmsand foils, particularly for opet and

aluminium.

adhesive for coextrusion coating of ldpe / tie / evoh or pa /tie onto opet or other films.
