High Adhesion Adhesive Granules Used For Alumunium Composite Panel Films
Grade:VF990
Product:Adhesive Film Resins for Aluminium-Plastic Composite Panel
Descriptions
Adhesive resin is a modified polyolefin with functional groups to bond firmly to common Polyolefin,Polyamide,Ethylene-Vinyl-Alcohol(EVOH),Wood and Metal,named Functional Polyolefin.
Since Polyolefin itself have no functional groups,it does not adhere to other materials.So we incorporate functional groups into the Polyolefin-Resin to endow the outstanding adhesiveness to other materials without losing all the characteristic benefits of the polyolefin.
VF990 is a maleic anhydride and vinyl acetate functionalized polyethylene polymer,easy to form film with excellent processability and adhesive strength.They are available in pellet form for use in conventional extrusion and co-extrusion equipment.
