Plastics

1. Plastic materials

   • In, general plastic materials are normal part of everyday.

2. Plastic materials

   • Plastics consist of long chains of molecules, mostly made of the element carbon.

3. Types of plastics

   • Natural plastics
   • Synthetic plastics

4. The origin of plastics

   • Natural plastics are obtained directly from vegetable or animal sorces.
   • Synthetic plastics are made with compounds that come from petroleum, natural gas abd carbon.

5. Plastic applications

   • Thermoplastics
     • PVC Window
   • Thermosetting plastics
     • Boats and aircraft coverings
   • Elastomers
     • Neoprene

6. Plastic of the future

   • The bioplastics
     • A plastic qualifies as “bio-based” when at least a fraction of it comes from a renewable raw material of plant or animal origin

7. Plastics clasification

   • Thermoplastics
     • Are composed of polymer chains that are weakly-connected to each other.
   • Thermosetting plastics
     • Are composed of polymer chains that are strongly-connected
   • Elastomers
     • Are composed of polymer chains that are laterally connected. They can be folded or rolled into a ball, like sting.
