Good insulator: PP is a good insulator and is therefore, used in electronic devices. The different variations in polypropylene have led the material to be known as the ‘steel’ of the plastic industry, as it can be used and manipulated a number of ways. This low melting point also means that polypropylene is highly flammable and limited in its ability to withstand higher temperatures and it is also susceptible to UV degradation and oxidation. It has a pungent odor of garlic or onions. It offers excellent fatigue resistance and elasticity, securing it a well-deserved reputation for toughness and durability.
