Book Description :

Recycling of Polyurethane Foams introduces the main degradation/depolymerization processes and pathways of polyurethane foam materials, focusing on industrial case studies and academic reviews from recent research and development projects. The book can aid practitioners in understanding the basis of polymer degradation and its relationship with industrial processes, which can be of substantial value to industrial complexes the world over. The main pathways of polymer recycling via different routes and industrial schemes are detailed, covering all current techniques, including regrinding, rebinding, adhesive pressing and compression moulding of recovered PU materials that are then compared with depolymerization approaches. The book examines life cycle assessment and cost analysis associated with polyurethane foams waste management, showing the potential of various techniques. This book will help academics and researchers identify and improve on current depolymerization processes, and it will help industry sustainability professionals choose the appropriate approach for their own waste management systems, thus minimizing the costs and environmental impact of their PU-based end products. Offers a comprehensive review of all polyurethane foam recycling processes, including both chemical and mechanical approaches Assesses the potential of each recycling process Helps industry-based practitioners decide which approach to take to minimize the cost and environmental impact of their end product Enables academics and researchers to identify and improve upon current processes of degradation and depolymerization

Book Description :

Polyester or polyethylene terephthalate (PET) is an unreinforced, semi-crystalline thermo-plastic polyester derived from polyethylene terephthalate. Its excellent wear resistance, low coefficient of friction, high flexural modulus, and superior dimensional stability make it a versatile material for designing mechanical and electro-mechanical parts. PET is fully recyclable and can be easily reprocessed into many other products for many different applications. However, unlike paper and other cellulose products, PET does not readily decompose. However, biodegradable additives are available that enhance the biodegradation of this plastic without affecting the physical properties. Formation of a flexible polyurethane foam is an intricate process employing unique hardware, multiple ingredients and at least two simultaneous reactions. The urethane forming reaction occurs between the isocyanate and the polyol. Polyurethanes, also known as polycarbamates, belong to a larger class of compounds called polymers. Polyurethanes can be produced in four different forms including elastomers, coatings, flexible foams, and cross-linked foams. Elastomers are materials that can be stretched but will eventually return to their original shape. They are useful in applications that require strength, flexibility, abrasion resistance, and shock absorbing qualities. Thermoplastic polyurethane elastomers can be molded and shaped into different parts. This makes them useful as base materials for automobile parts, ski boots, roller skate wheels, cable jackets, and other mechanical goods. When these elastomers are spun into fibers they produce a flexible material called spandex. Spandex is used to make sock tops, bras, support hose, swimsuits, and other athletic apparel. Co-injection is the process of injecting two resins simultaneously through a single gate to form a multi-layer structure. Recently, there has been a re-emergence of interest in co-injection technology spurred on by the development of new resins, barrier systems, controls, and hardware technologies. Increasing demand of polyethylene terephthalate (PET) from food and beverage sector like in carbonated soft drinks packaging, increase demand for packaged food due to rise in consumption of frozen and processed food, rise in demand for electronics and automotive applications/industries and ecofriendly substitution are the most important driving factors in the polyethylene terephthalate market. Also, rapid urbanization, innovative packaging and high economic growth is contribution in increasing the demand for polyethylene terephthalate regardless of the geographical location. This book will be a mile stone for its readers who are new to this sector, will also find useful for professionals, entrepreneurs, those studying and researching in this important area.

Book Description :

Abstract: Flexible PU foam was synthesized by using recycled PU foam polyol (Infrigreen) which contain 4 functionality obtained from glycolysis wasted PU foam, as a polyol. PU foam is prepared by incorporation of recycled PU foam polyol 2, 4, 6, 8 and 10wt% in petrochemical polyol (CARADOL.SA34-05) which contain 2 functionality. Triethlylenediamine (TEGOAMIN 33) was used as the gelling catalyst. Polyether modified polysiloxane (TPGAOSTAB B8715 LF2) was the surfactant. Distilled water was used as a blowing agent to generate foam. Polymeric methylenediphenyl diisocyanate (pMDI) which contain 2.7 isocyanate groups/molecule was used for generate urethane linkage and carbon dioxide. The parameters investigated are characteristic time, i.e. cream time, gel time, rise time and tack free time, cell structure and cell morphology, tensile properties, compressive properties and compression set were compared with petrochemical based PU foam. It was found from the research that, cream time, gel time, rise time and tack free time, decrease with the recycled PU foam polyol content. It was also found that the incorporation of recycled PU foam polyol led to the increase in smaller cell size and large distribution of cell size. Tensile properties and compressive properties of PU foam increase with polyol functionality, including crosslink density and urea formation in PU foam. Decreasing of shape recover properties of PU foam obtained at high recycled PU foam polyol contents. This was caused by the deformation of hydrogen bonding between hard segments of PU chains. These results indicate that tensile properties and compressive properties of PU foam enhance by incorporation of recycled PU foam polyol.
