Name the three main categories of synthetic plastics.
(a)
Elastomer plastic is known to have rubber like properties. It can be stretched and can return to their original shape when released.
True
False
Oxo-degradable plastics have additives that promote short degradation e.g. less than five years. These help the plastic break down into a fine powder from the effects of
Heat
Air
Oxygen
Moisture
Fire
