Polypropylene vs. Polyethylene: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Polypropylene is a thermoplastic polymer used for its toughness and resistance to chemicals, while polyethylene is known for its flexibility and is widely used in packaging.
Key Differences
Polypropylene, a thermoplastic polymer, is known for its high resistance to chemicals and solvents, in contrast to polyethylene, which is praised for its flexibility and is the most common plastic.
