Plastics technology

• Describe the basic physical and chemical properties of thermoplastics, thermosetting polymers and elastomers.
• Calculate the number- and weight-average molecular weight and polydispersity index for a given polymer sample, and explain their importance for polymer processing and properties.
• Explain the correlation between chemical structure, intermolecular forces and macroscopic properties such as mechanical strength and stiffness.
• Analyze and calculate the mechanical properties of polymer-based reinforced composite materials, including fiber- and nano-composites, using simple models (e.g., ‘rule of mixtures’).
• Describe the principals of thermal analysis for the determination of glass transition, melting and crystallization temperature.
• Select and justify the selection of a polymer material for a specific product, based on its functional requirements.
• Use material databases to select appropriate materials and to determine suitable process and design parameters.
• Describe and compare common processing methods; injection molding, extrusion and 3D-printing, focusing on the function, operation and advantages versus limitations.
• Account for the environmental impact of plastics and rubber, including raw material extraction, production, use, and recycling.

Structure and properties of plastics and rubber. Fiber-reinforced plastic. Systematic materials selection, characterization and identification.
