Influence of various molding conditions on the uni-, bi-, and triaxial impact properties of poly(vinyl chloride) (PVC)

This study discusses the influence of molecular weight, melt temperature, mold temperature, and aging on the impact characteristics of molded PVC. Tensile impact (uniaxial), instrumented drop‐dart impact (biaxial), and Izod impact (triaxial) methods were utilized to assess the impact properties of t...

Description
Summary:This study discusses the influence of molecular weight, melt temperature, mold temperature, and aging on the impact characteristics of molded PVC. Tensile impact (uniaxial), instrumented drop‐dart impact (biaxial), and Izod impact (triaxial) methods were utilized to assess the impact properties of the material under investigation. It was found that the impact properties were affected by aging more than by the changes in the melt temperature or the mold temperature. Additionally, the molecular weight played a significant role in influencing the impact properties of PVC.
