Eco-Friendly Polypropylene Composites Filled with Crab Shell Powder: A Review

Article Preview

Abstract:

Shell Powder is a new material in the field of sustainable composite materials. In this study crab shell powder, an abundant natural waste resource, is used as a filler in polypropylene composites to improve mechanical properties and be friendly to the environment. The use of crab shell powder not only reduces waste entering the environment but also provides added value to the composite product. Polypropylene, a frequently used thermoplastic polymer, was chosen as the matrix due to its processability and good resistance to various chemical environments. These composites exhibit improved mechanical properties, including tensile strength and flexibility, compared to pure polypropylene. In addition, they also exhibit improved thermal stability and resistance to environmental degradation. Thus, these composites offer a promising alternative to conventional materials in a wide range of applications, including home appliances, automotive, and sports equipment, 3D printing, Medical Applications, fishing industry and food packaging while minimizing environmental impact.
