polymeres

• types of polymers:

  • thermo-polymers
  • thermoset
  • biopolymeres
• Thermo-polymers are plastics that can be melted, shaped into different forms, then cooled to harden again.
• Thermosets are plastics that cannot be remelted or reshaped once they have been formed.
• properties of thermo-polymers:

  • good insulator
  • hygienic
  • non biodegradable
  • made from finite sources(oil,coal,gas)
  • waterproof
  • can be reformed by heat
  • can be forced in to complexes shapes
• properties of thermoset:

  • tough but brittle
  • non-biodegradable
  • made from finite resources(oil,coal,gas)
  • very good insulator-electrical/heat
  • can't be reformed
• properties of biopolymeres:

  • manufactured from plants
  • biodegradable
• types of thermo-polymeres:

  • Hips
  • acrylic
  • polysterin
• types of thermoset:

  • polyester
  • silicone
  • epoxy
• types of biopolymeres:

  • starch
  • agar
  • chitosan
