Page 24 SANITIZED SUBMISSIONCONSISTATM C601 Catalyst is the first 6th generation Ziegler Natta catalyst in the global PP industry and contains as a critical component the

PMN substance. The PMN substance is a replacement for previously used phthalates in similar catalysts. As a non-phthalate based catalyst system, CONSISTATM C601 Catalyst has broad applicability and enables polypropylene producers to develop high-performance polypropylene for goods that are lighter, cleaner and clearer. The catalyst’s drop-in technology requires no capital or upgrades to existing facilities.
