Evaluation of recycled resin: Supporting the quality improvement of recycled materials.

We will identify the factors causing quality deterioration and contribute to improving the quality of the final product!

Introducing "Model Case 3: Supporting Quality Improvement of Recycled Materials." Products made from recycled market resources often exhibit lower quality compared to those made from virgin materials. As the use of recycled materials increases in the future, it is expected that the quality requirements will also rise, necessitating countermeasures. By utilizing technologies such as investigating the factors contributing to the performance decline of recycled materials, we can identify the causes of quality degradation. If we can avoid or reduce these factors during the collection, sorting, and recycling processes, we can improve the quality of the final products. [Investigation of Factors Contributing to Performance Decline of Recycled Materials] - Resin degradation assessment: Confirmation of molecular weight reduction through molecular weight distribution measurement - Investigation of fracture causes in resin materials: Fracture surface analysis using optical microscopy, SEM, etc. - Evaluation of moldability: Assessment of moldability through melt viscosity, elongation viscosity, etc. *For more details, please refer to the related links or feel free to contact us.
