Formation techniques
lamination
Thermoplastic produced by the extrusion method is passed through a series of hot cylinders to produce sheets of varying thickness.
With this technique, we can produce different finishes
Used to form: worktops, to cover surfaces of kitchen cupboards and
drawers
vacuum forming
-
Used to form: bathtubs, dashbnards, shop signs and egg boxes
-
extrusion
Used to form; wrapping, lining for electric cables, tubes and pipes.
-

Properties of plastics
-
Strength, elasticity, rigidity and flexibility are characteristics of many plastics
Other properties
-
-
mechanical : malleablity, ductility and mechanical resistance
-
other properties:low density, impermeability
-
-
Plastics are materials formed by polymers. The polymers in plastics are
made from long chains of carbon atoms.
