Typical reactions for chain assembling are polyaddition (continuous or step wise) and condensation polymer-ization (polycondensation) [1] (Figure 1.1).. Around 4 percent of annual petroleum consumption globally is used to produce plastic, with an additional 4 percent employed to power manufacturing processes for plastic production. An example would be to pull on a 1" wide piece of paper that is 4" long. Plastics are mainly highly polymerized compounds consisting of carbon and hydrogen, made from substances such as petroleum and natural gas. Introduction to Extrusion 1.

Introduction to Plastics Engineering provides a single reference covering the basics of polymer and plastics materials, and their properties, design, processing and applications in a practical way. Several hazardous Materials called “alloys” are manufactured by the sim-ple mixing of two or more polymers with a resulting blending of properties which are often better than either individual material. Plastics are (mostly) synthetic (human-made) materials, made from polymers , which are long molecules built around chains of carbon atoms , typically with hydrogen, oxygen, sulfur, and nitrogen filling in the spaces. ii Introduction Waste is now a global problem, and one that must be addressed in order to solve the world's resource and energy challenges. 7�f(����4�E��hc����z�!s���e�-:J���R4�ev�i �pd���.~�R�|D�#bʼn�],���7�o�~�����3w����W�$wQ&�&�d���ӎs ϼ�� �0��gȚ]��~Ɋ]n�{�m�r�D"/��M PDF. 0000001312 00000 n In Chemical Resistance of Thermoplastics, 2012.
