Transcript of "Science"

  1. 1. Elastomers Group 8: Kieran Sy, Earl Dy, Merwin Chang, Brandon Te, Jonah Dee,
  2. 2. :Elastomers: <ul><li>A category of pliable plastic material that are good at insulating, withstanding deformation, stretching many times it’s length, and molding into different shapes </li></ul><ul><li>Basically rubber </li></ul>
  3. 3. :Elastomers: <ul><li>The molecules in a piece of rubber, any kind of rubber, have no order to them. They just wind and tangle around each other in one jumbled mess </li></ul>
  4. 4. :Elastomers: <ul><li>When the rubber is pulled, the molecules are forced to line up in one direction and they become orderly </li></ul>
  5. 5. :Elastomers: <ul><li>When you let go of this rubber sample you've been stretching, the molecules will quickly go back to their tangled and disordered state </li></ul>
  6. 6. :Types of Elastomers: <ul><li>:Polyisoprene </li></ul><ul><li>One of the most well known natural polymers is polyisoprene, or natural rubber. Ancient Mayans and Aztecs harvested it from the hevea tree (rubber tree) and used it to make waterproof boots and the balls that they used to play a game similar to basketball. </li></ul>
  7. 7. :Types of Elastomers: <ul><li>:Polychloroprene: </li></ul><ul><li>It was the first synthetic elastomer, or rubber to be a hit commercially. It is resistant to oil and It was invented by the Arnold Collins </li></ul><ul><li>Sold under the name Neoprene ® </li></ul>
  8. 8. :Types of Elastomers: <ul><li>Polybutadiene </li></ul><ul><li>Polybutadiene was one of the first types of synthetic elastomer , or rubber, to be invented. It's a lot like natural rubber, polyisoprene. Car parts like belts, hoses, and gaskets are made from polybutadiene because it stands up to cold temperatures better than other elastomers </li></ul>
  9. 9. :Types of Elastomers: <ul><li>:Polystyrene or SBS: </li></ul><ul><li>Polystyrene or SBS , is a hard Elastomer That’s used for things like the soles of shoes, tire treads, and other places where durability is important </li></ul>
  10. 10. :Types of Elastomers: <ul><li>:Polyisobutylene: </li></ul><ul><li>Polyisobutylene is a synthetic rubber which can hold gas for a long time. Because polyisobutylene will hold air, it's used to make things like the inner liners of tires and the inner liners of basketballs. </li></ul>
  11. 11. Uses <ul><li>Wheels of Automobiles </li></ul><ul><li>Balls used in sports </li></ul><ul><li>Bicycle seats </li></ul><ul><li>Rubber Shoe soles </li></ul>
