Metallocene Copolymers for Extrusion Coating Applications Designed Specifically for Exceptional Ultimate Hot Tack and High Temperature Hot Tack Strength

摘要

Metallocene copolymers produced by single site catalyst systems have made significant inroads into extrusion coating and lamination applications. One performance attribute previously lacking for these polymer systems was hot tack, especially ultimate hot tack strength and high temperature hot tack strength. Historically, acid copolymers and ionomers have provided the best options for hot tack but at significant economical disadvantages. Polyolefin Plastomers (POP's) which are metallocene polymers, have now been developed with equal, and sometimes better, ultimate hot tack and high temperature hot tack as compared to current acid copolymers and ionomers.
