New Stabilizer Solutions for Polyolefin Film Grades, 2003 European PLACE Conference Proceedings

Over the years the plastic industry is launching a variety several new polyolefin products, including metallocenebased and bimodal polyethylenes and polypropylenes. Nevertheless the industry has matured quite considerably over the past 30 years. In such a mature industry, there are still many incumbent products which have established positions in existing markets. These products have been successful in meeting the most important needs in their markets but there still remains areas where performance can be improved or where deficiencies exist. These opportunities could encompass processing improvements, reduction of defects, reduced discoloration, or product stewardship concerns. Successful attempts to make improvements upon these incumbent products seem to depend from a technical stand point on two factors: a wide spectrum of products from which to choose (toolbox) and people with knowledge of the chemistries and the technologies they will be applied to. This paper will describe two examples of new approaches to base stabilization of polyolefins.
