MFGT 104Materials and QualityChap 5: Polymers and Elastomers;Polymers and Elastomers;Definition of Plastics;Early Modified Natural Materials; ;Automotive Plastics and Composites Use;Major Plastic Materials1994;Recycling of Plastics;Polymer Materials;Polymer Materials;Macromolecules;Amorphous- Molecular structure is incapable of forming regular order (crystallizing) with molecules or portions of molecules regularly stacked in crystal-like fashion. A - morphous (with-out shape) Molecular arrangement is randomly twisted, kinked, and coiled ;Amorphous Materials;Crystalline- Molecular structure forms regular order (crystals) with molecules or portions of molecules regularly stacked in crystal-like fashion. Very high crystallinity is rarely achieved in bulk polymers Most crystalline polymers are semi-crystalline because regions are crystalline and regions are amorphous Molecular arrangement is arranged in a ordered state ;Crystalline polymers (PE, PP, PBT, PA,etc);Crystalline Materials;Carbon Chain Polymers;Homopolymers;Carbon with Other Elements in Backbone;Thermosets;Polyester and Polyurethane;Polyurethane Chemistry;Applications for Thermosets;Applications for Thermosets;Elastomers;Rubbers;Rubber Additives and Modifiers;Synthetic Rubber;Synthetic Rubber;Thermoplastic Elastomers;Processing of Polymers;Injection Molding Process and Cycle Time;Extruder Equipment;Compression Molding Process;Resin Transfer Molding ProcessRef: MSU Tutorial- /trp/liquid/rtm/
