Supplementary information for the publication: Influence of soapstone waste on the mechanical and rheological properties of HDPE

Soapstone waste was characterized through X-Ray diffraction, automated image analysis, FTIR and Raman spectroscopy. The waste was used as filler in high-density polyethylene composites. The composites with different filler fractions were characterized by tensile testing and rheology analysis.本研究通过X射线衍射（X-Ray Diffraction）、自动化图像分析、傅里叶变换红外光谱（FTIR）及拉曼光谱对皂石废料进行了表征。将该皂石废料作为填料应用于高密度聚乙烯复合材料中，针对不同填料掺量的复合材料开展拉伸测试与流变分析以完成性能表征。
