Abstract
Over the years, the molecular design of high density polyethylene has evolved through innovation. One such innovation was the development of PE 4710 bimodal resins for pipe applications. These high density bimodal resins have improved the performance attributes such as increased durability, longer design life, increased pressure rating, and increased hydraulic capacity for polyethylene plastic piping systems. This paper details the design improvements at the molecular level and explains how these changes affect the performance attributes that are important to polyethylene plastic piping systems.
