Today’s sophisticated packaging systems demand the use of a variety of resins in a single structure. Westlake’s EMAC®, EBAC® and TYMAX® GT functionalized product lines have the resins needed to tie these multilayer structures together. The materials act as extruded tie layer resins or tie layer polymers or adhesives for these difficult to adhere situations. They also function as a compatabilizer in a composite of blended materials.
