What Does Polyolefin Mean?

Polyolefin is a type of polymer that consists of simple olefins. Polyolefin is categorized as a type of thermoplastic, and it is one of the most popular. Polyolefin is comprised solely of hydrogen and carbon.

Polyolefin is one of the most abundant polymers in use today. The applications for polyolefin are many, including consumer products such as toys and consumer storage tubs, and industrial electronics and containers.

There are two major types of polyolefin: polypropylene and polyethylene.


Corrosionpedia Explains Polyolefin

The two most important groups under the polyolefin family are polypropylene and polyethylene.

  1. Polypropylene is known for its mechanical properties. It has excellent strength and performs well in environments where it is subjected to fatigue. It also does well in applications where high and low temperatures are found (within certain limits).
  2. Polyethylene is an polyolefin that is translucent, which is good for applications where exposure to light is not desirable. Also, polyethylene does not rip easily and is known for its flexibility.
