differences between plastics

• What happens to a thermosetting polymer when heated?

  It strengthens and cannot be remoulded
• Why can't a thermosetting polymer be remoulded after initial forming?

  Because it undergoes a chemical change
• What is a key characteristic of thermoplastics?

  They can be reheated and remoulded
• How does reheating affect thermoplastics?

  It allows them to be remoulded without chemical change
• What are the main differences between thermosetting polymers and thermoplastics?

  • Thermosetting polymers:
  • Strengthen when heated
  • Cannot be remoulded after forming
  • Thermoplastics:
  • Can be reheated and remoulded
  • No chemical change occurs upon reheating
