Drawn Fiber Polymers: Chemical/Mechanical Features
Featured Product from Zeus
Drawn fiber is generally superior to standard monofilament due to the drawing process. Examination of the chemical aspects of the materials used to create drawn fiber provides valuable insights into their properties. Polymers such as PFA, ETFE, ECTFE, FEP, PEEK, and especially PVDF represent particularly instructive models to explain features such as dipole-dipole chain interactions, London forces, and chain flexibility.
Building on this foundational knowledge, mechanical and physical properties can be explained with greater clarity. Comparison of features such as crystallinity, glass transition temperature (Tg), melt temperature (Tm), and strength provides a backdrop for discussion of stress-strain relationships. Drawn Fiber Polymers: Chemical and Mechanical Features provides practical knowledge and understanding to help choose a best drawn fiber based on material, properties, and environment.
This technical paper explores many key topics in-depth, including:
- Drawn fiber vs conventional monofilament
- Fluorine chemistry and drawn fiber polymers
- Unique features of PVDF
- How chemical features translate to critical mechanical attributes
