  • PE has excellent mechanical processing performance, but its surface is inert and non-polar, resulting in poor printability, dyeing, hydrophilicity, adhesion, anti-static performance, and compatibility with other polar polymers and inorganic fillers. In addition, its wear resistance, chemical resistance, environmental stress cracking resistance, and heat resistance are poor, limiting its application range. Modification is needed to improve its performance and expand its application field.
