Polymers
Inter-molecular bonds: Covalent and Van der Waals or Hydrogen.
Properties
- Has a repeating structure
- lightweight
- corrosion-resistant
- easy to process at low temperatures
- generally inexpensive
- generally low strength
- generally high toughness
- good heat, electrical insulators (but conductive polymers exist)
Examples
