Features & Benefits

Materials Features
Key Features
  • 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 ontosubstrates 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 aluminum lids for PP or PP coated cups and containers with controlled opening forces.

Processing Parameters

OREVAC® 18750 is not corrosive and is readily processed with standard polyolefin equipment. Conditions typically used in extrusion of polypropylene resins are suitable. Typical extrusion temperature settings could be:

Zone 1 Zone 2 Zone 3 Zone 4 Fittings Channels Die
200-220°C 220-250°C 250-275°C 275°C 275°C 275°C

Final profile and settings depend on the line and the multi-layer structure being run. Although it is not necessary for short runs, it is recommended to dry OREVAC® 18750 pellets prior to
extrusion in order to reduce die build-up during long runs. Typical drying conditions would be from 2 to 4 hours at 80-90°C under dry air.
