plastic materials

1. THERMOPLASTIC

   • Organic materials that melts with heat , they are formed when they are in a phase of melting, this means that they heat up, form, and then cool down into their final form.
   • TYPES
     • PC
       • rigid, transparent , resistant to heat
         • technologycal devices
     • PP
       • esay to model , dye resistantto splitering solvents
         • folder , toys ...
     • PS
       • poor chemical condition flexible transparentrigid ...
         • packaging in general
     • PE
       • resistance to chemicals,
         • bottles plastic bags etc
     • PVC
       • very hard to impact and absortion of polymer
         • it is used for construction wires pipes etc
     • Tefon
       • resistant to heat , chemicals and electricity
         • kitchen utensils
     • PET
       • colorless, flexible , recyclable, easy to dye
         • it si used for bottles
   • STRUCTURE

2. THERMOSET

   • the polymer chains of thermoset plastic criss-cross to form networds , the plastic can be shaped using heat
   • TYPES
     • melamine
       • resistance to heat and chemicals esay to clean
         • coating for wooden board and manufacture of kitchen cupboards
     • bakelite
       • handles for kitchen utensils
         • hard and brittle dark plastic that reists heat very well
     • polyester resins
       • rigid strengthed with fibreglass
         • domesttic swimming pools car bodies ...
   • STRUCTURE

3. ELASTOMERS

   • elastic materials that recovered their shape when a force stops
   • TYPES
     • neoprender
       • flexible waterproof and insulated
         • immersion suits...
     • rubber
       • elastic polymer
         • tyress rubber hoses...
     • silicone
       • low toxicity, thermal conductivity
         • kitchen utensiles , mobile phone case...
   • STRUCTURE
