Performance modifying techniques for recycled thermoplastics

چکیده
Petro-derived commodity thermoplastics are relatively inexpensive, lightweight, and non-biodegradable materials, which can be readily molded at high temperatures into a range of products. The manufacturing such thermoplastic resins products has increased dramatically over the last 70 years. plastics based on polyolefins, polystyrenes, polyesters occupy largest share (80%) world's plastic markets. However, disposal waste created considerable environmental concerns. Therefore, environment protection agencies manufacturers constantly seeking appropriate techniques for recycling or upcycling new In recent years, rates approximately 9 to 15% out total produced annually in United States Europe, predominantly limited individual fractions as HDPE PET. process is associated with various expensive time-consuming sorting techniques, not economically attractive industries. A significant issue when multiple blended, they often chemically compatible, resulting phase separation inferior-quality materials. it important apply certain performance modifiers during re-extrusion thermoplastics, include compatibilizers, coupling agents, impact modifiers, many others. There different additives available, suitable improve mechanical other properties polymer blends composites, these also used improving recycled thermoplastics. This review article summarizes chemical approaches, thermomechanical materials superior via interfacial adhesion homogeneity blends.
