Plastics for Engineers: An Introductory Course focuses on the nature, engineering properties, and applications of plastics. The publication first elaborates on polymers, structure of polymeric materials, and mechanical properties of plastics. Discussions focus on stress cracking, damping, effect of vibrational stress, impact resistance, rotational transitions, crystalline melting point, linear and network polymers, addition and condensation polymers, and thermosetting and thermoplastic materials.The manuscript then ponders on the electrical, physical, and chemical properties of plastics, expanding, plasticizing, filling and reinforcing, and fabrication. Topics include transfer molding, casting, welding, plasticization, water absorption, resistance to solvents and chemicals, specific gravity, friction, thermal conductivity, polarization, insulation resistance, and dialectic constant and strength. The text takes a look at silicones, rubbers, thermosetting plastics, non-ethenic thermoplastics, vinyl plastics, polyolefins, and adhesives and coatings.The publication is a recommended source material for engineering students and researchers interested to conduct studies on the nature, engineering properties, and applications of plastics.
