Arkema OREVAC® 18750 Maleic Anhydride Modified Polypropylene
Categories: Polymer; Thermoplastic; Polypropylene (PP)

Material Notes: Description

OREVAC 18750 is a coextrusion coating adhesive based on a maleic anhydride modified polypropylene resin. It combines the processability of an extrusion coating resin with the thermal resistance of polypropylene. OREVAC 18750 is available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyolefins.

Applications

OREVAC 18750 is a tie resin to be used in extrusion coating and extrusion lamination technologies. It has been designed to develop adhesion in these processes onto substrates like aluminum foil, paper, or PP films and in coextrusion with resins like PP and PA. OREVAC 18750 exhibits excellent processing properties, particularly regarding drawability, neck-in and melt stability. In addition to adhesive properties, the special formulation of OREVAC 18750 allows to design aluminium lids for PP or PP coated cups and containers with controlled opening forces.
