Uses of Polymers

Uses of Polymers

1. Light, low density polymers can be used in smart materials for example Lycra.

2. polymers can be made to be biodegradable, especially materials such as corn starch.

3. There are dental polymers which are often used for tooth fillings.

4. They can also be used in waterproof packaging.

5. Memory foam is an example of smart materials.

   • Gets softer as it gets warmer (body heat) and therefore is able to mould to your shape when you sleep on them etc.

6. Negatives

   • They are hard to get rid of.
     • Most polymers are not biodegradable which mean that they dont naturally rot easily.
     • Often become stuck in landfill with no other use.
     • As crude oil gets used up, products made out of polymers will become rarer and the price of them will go up.
