Multifaceted Evaluation of Plastics: Differences due to Kneading Conditions

User Benefits

- Multifaceted evaluation by instrumental analysis can provide a more detailed understanding of changes in properties due to differences in molding conditions such resin material kneading conditions, and the data obtained are effective for studying the optimum molding conditions. - Use of the MALDI-TOF MS makes it possible to analyze changes in the molecular structure of resin materials during molding.

Introduction

It is necessary to study the optimum conditions for injection molding of resin because various molding conditions, such as temperature, pressure, and time, affect the properties of molded products. In particular, when using blended resins, changes in property due to differences in kneading during molding are a concern. In this experiment, multifaceted measurements of the properties of samples prepared under different kneading conditions (differences with/without kneading treatment by a kneading machine) were carried out using a polycarbonate (PC)/acrylonitrile-butadiene-styrene (ABS) blended resin to confirm the effects of kneading conditions.
