Seven Types of Mineral Powders for Polypropylene Modification
Polypropylene (PP) is a widely used thermoplastic polymer, known for its easy processing and excellent properties. This makes it essential in industries such as packaging, home appliances, and automotive parts. Despite its widespread use, PP has certain limitations. These include high thermal shrinkage, poor performance in low temperatures, and inadequate impact resistance. These shortcomings have driven the development of strategies to enhance PP’s properties. One effective method is the incorporation of various mineral powders for polypropylene modification, enhancing its overall performance. By adding inorganic mineral powders, such as calcium carbonate, talc, and mica, the thermal stability of PP can be improved. This also enhances its impact strength and overall performance. […]
