PLASTIC




 PLASTIC



Plastic is a material that has some special properties

  • Elasticity: The plastic can be stretched and return to its initial position, but some kind of plastics  are not elastic.
  • Density: For how tough it is, it is not a heavy material.
  • Fragility: There are very fragile plastic but others are very hard.
  • Utility: Is a material that is used for many things such as bags, toys, containers etc.
We  must  recycle because it is a highly polluting material to the environment and seas.
