【Abstract】 The stress-strain behavior, flex lifeand melt flow property of a ultra-highmolecular weight UHMW-FEP copolymerwere studied. The results showed that theUHMW grade has a higher tensile strength at high temperature and a higher flex lifethan commercial grade and can be meltprocessed under pressure.更多还原
