PLASTICS

  • WHAT IS PLASTICS?

  • Plastic is a synthetic polymer which consist monomers that combine togather to form new molecule known as polymer

  • Plastic is from by the process of polymerisation of monomers from petroleum or natural gas.

Thermoplastics
Thermoplastics

  • Plastic that cannot withstand heat.

  • Consist of molecules withoutcross links between their polymers.

  • The molecular structure easy slide over when heated.

  • Soft when heated and can be mould repeatly.

  • Can be recycle to form new substances.

  • Example: polythene, perspex, PVC, polystyrene

Characteristics thermoplastics
Characteristics Thermoplastics

Characteristic

  • Low melting & boiling point

  • Good electric insulator

  • Can be mould repeatly

  • Can withstand chemicals(acid/alkalis)

  • Dissolve in organic solvents

  • Colourless

Thermosetting plastics
Thermosetting plastics polystyrene.

  • Heat resistance plastics

  • Have cross link between their polymers

  • Cross link prevent them from sliding over one another when heated.

  • Can be moulded once only and cannot be recycle.

Plastics made from polymerization of or natural gas.

Combination monomers known as

Two classification of plastic are and thermosetting plastics.

Plastics is good insulator.

Thermosetting plastics have that prevent it sliding over when heated.

Thermoplastics have melting point.

Thermoplastics can be many times.

PVC, polystyrene and are the example of thermoplastics.
