Basell announces worldwide availability of new polyethylene catalyst
Basell announced that its new family of Ziegler catalysts designed for use in gas phase polyethylene technologies is now available under the grade name Avant Z 230 for purchase on a global basis.
"The new Avant catalysts can produce the entire range of narrow molecular weight LLDPE, MDPE and HDPE," said Michael Mulrooney, senior vice president of Basell's Technology Business. Typical applications include film, injection moulding and rotomoulding grades.
"Most gas phase polyethylene catalyst systems use silica supports," said Mulrooney. "Silica supports are widely available, but morphological stability in the reactor can be a problem." The Avant Z 230 catalyst uses a magnesium chloride support. The combination of new proprietary catalyst chemistry, with a more stable support structure, has resulted in a catalyst with expanded product properties and improved operational stability.
