2. Elastomers = Definition Any of various elastic substances resembling rubber Any of various elastic substances resembling rubber Basically, Elastomer means rubber. Basically, Elastomer means rubber.

3. Polymers a substance (as polystyrene) consisting of molecules that are large multiples of units of low molecular weight a substance (as polystyrene) consisting of molecules that are large multiples of units of low molecular weight

4. What is an Elastomer? An Elastomer is a polymers having the elastic property or the flexibility of a natural rubber. An Elastomer is a polymers having the elastic property or the flexibility of a natural rubber. One thing that make elastomers special is they can be stretched to many times their original length, and can bounce back into their original shape without permanent deformation.

5. Industries often rely on elastomers. These industries includes automobiles, sports, electronics, and assembly line factories. Industries often rely on elastomers. These industries includes automobiles, sports, electronics, and assembly line factories. Why is this so? Why is this so? easy to sculpt when they are in their softened, resinous state easy to sculpt when they are in their softened, resinous state Once it hardens, it’s impervious or it’s hard to break. Once it hardens, it’s impervious or it’s hard to break.

6. Elastomer: Properties  Flexible  Does not conduct electricity  Lightweight  Hard  Dense  Resistant from corrosion from different chemicals

7. Uses of Elastomers Elastomers are used in: Elastomers are used in: Wheels of a skate board Wheels of a skate board Sole on a tennis shoe Sole on a tennis shoe insulation covering speaker cables; insulation covering speaker cables; telephone lines telephone lines

8. Ability Can be compounded Can be compounded If you combine it with other polymers, it will “upgrade” its ability like making it less likely to soften at high temperatures or break down around ozone gas. If you combine it with other polymers, it will “upgrade” its ability like making it less likely to soften at high temperatures or break down around ozone gas. It can also fuse with metal, hard plastic, or different kinds of rubber, with excellent adherence meaning it’s hard to remove. It can also fuse with metal, hard plastic, or different kinds of rubber, with excellent adherence meaning it’s hard to remove.

9. Crosslinking Crosslinked property- ability to deform and return to their previous shape Crosslinked property- ability to deform and return to their previous shape Crosslinking means different polymers have been linked together Crosslinking means different polymers have been linked together

10. Negative Aspect Difficult to recycle Difficult to recycle
