Course Overview

The scope of this course includes general purpose plastics, engineering and high performance plastics, and thermoplastic elastomers. This course is intended for material specialists, design engineers, tech service personnel, procurement specialists and others who wish to broaden their understanding of thermoplastic materials, how and why they are used, and issues related to risks of material failure.

Day 1 (optional) presents relevant fundamentals of polymer science including; polymerization mechanisms, kinetics, and molecular weight development, and backbone structure-property relationships. Day 1 also provides fundamentals of how major commercial industrial and high performance polymers are synthesized.

Days 2 and 3 provide a frame work for: candidate material selection, qualification for specific use, and developing meaningful specifications in the context of the fundamentals of ISO design control processes. Consensus standards such as: ISO, SAE and ASTM standards, recommended practices, and specifications are identified and discussed. Risk factors are identified and a range of failure case studies are reviewed illustrating many of the common risks such as stress cracking, brittle failures, creep, environmental and chemical exposure, fatigue, processing, and part design defects. Relevant testing and analysis techniques are reviewed.

Chemistry, fundamental properties, strengths and weaknesses, and common uses are detailed for a range of materials including for example: PE, PP, PS, ABS, PVC, PA, PC, POM, PPO, PEI, PEEK, PSU, PPS, PAI, TPU, COPES, TPVs, TPOs, PTFE, PFA, FEP, and more.
