Due to the tertiary carbon atom PP is chemically less resistant than PE (see Markovnikov rule).
Polypropylene is the second-most widely produced commodity plastic (after polyethylene) and it is often used in packaging and labeling.
Non-oxidizing acids and bases can be stored in containers made of PP.
At elevated temperature, PP can be dissolved in nonpolar solvents such as xylene, tetralin and decalin.
Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar.
Its properties are similar to polyethylene, but it is slightly harder and more heat resistant.
