Measuring Polyethylene (PE)-Polypropylene (PP) Blend Samples

Introduction

Polymeric materials are blends of two or more types of high molecular materials that are mixed to improve mechanical properties. Blends are often created to obtain properties that a single type cannot possess; however, this requires an understanding of component ratios. Unlike copolymers, mechanically blended polymeric materials exhibit the characteristics of each component, such as melting and crystallization, and multiple changes derived from each component can be observed through measurement with a DSC (differential scanning calorimeter). This research utilizes this process to introduce examples of determining the component ratios of blended high molecular materials by measuring the heat of fusion with a DSC.
