Abstract
The key to successfully implementing polymer blends in end‐use applications includes an understanding of performance requirements and the physical property balance of the blend, as well as the provision of financial incentive to the fabricator, The economic gain is calculated for two cases where blends were introduced to displace another material: a blend which gives higher productivity for blown film applications and a blend which allows for increased flow and a gage reduction for an injection molding application. As the resin cost usually accounts for more than seventy percent of the final product cost, the resin or blend cost affects the economic gain (if any) from the fabricator's point of view. Therefore, successful commercial implementation of a new resin or blend depends on its relative cost and benefit to other commercially available materials.
