3. The IAPD Plastics Primer, Module 2 Definitions Thermoplastic Thermoset

4. The IAPD Plastics Primer, Module 2 Types of Thermoplastics Imidized materials Amorphous plastics High performance Engineering Commodity Semi-crystalline plastics High performance Engineering Commodity

5. The IAPD Plastics Primer, Module 2 Amorphous vs. Crystalline Thermoplastics Amorphous (a-morphous = without shape) - The polymer chains are in random arrangement. Molecular structure is incapable of forming regular order (crystallizing) with molecules or portions of molecules regularly stacked in crystal-like fashion. Molecular arrangement is randomly twisted, kinked and coiled. Crystalline - The polymer chains form a regular pattern. Molecular structure forms regular order (crystals) with molecules or portions of molecules regularly stacked in crystal-like fashion. Molecular arrangement is arranged in an ordered fashion.
