About the book
Thermosoftening plastics are polymers that can be manipulated into different shapes when they are hot, and the shape sets when they cool. If the polymer is reheated again, it can be reshapen. Modern thermosoftening plastics soften anywhere between 65ºC and 200ºC. In this state they can be moulded in a number of ways and returned to the plastic state by reheating. By this characteristic they differ from thermoset plastics. Thermosoftening plastics are fully recyclable, since they do not have covalent bonds between neighbouring polymer molecules. Methods of shaping softened plastics include: injection moulding, rotational moulding, extrusion, vacuum forming, compression moulding. The scope of this book covers the areas of thermosoftening plastics, thermoplastics materials and their characterization. The following topics will be covered: • Thermal analysis (differential scanning calorimetry, heat deflection temperature test) • Optical properties tests (fluorescence spectroscopy, UV spectroscopy) • Mechanical properties tests (thermogravimetry, rheometry, short term tensile test) • Electrical properties tests (dielectric spectroscopy, electrical conductivity test) • Acoustic properties tests (ultrasonic test, acoustic emission test).
