Methods, compositions and blends for forming articles having improved environmental stress crack resistance

摘要

Several processes for the manufacture of thin-walled tubes are described, including: injection molding an article and annealing the article, injection molding a blend of a polymer and a high melt flow polymer, injection molding a blend of a polymer and nanoparticles or nanocomposites. Using nanoparticles to improve ESCR and/or tear resistance of a polymer or blend is also disclosed.
