The most widely-used plastic in the world today. In cosmetics, used for many things, including as a stabilizer and viscosity-increasing ingredient.
Polyethene or poly(methylene)
|Melting point||115–135 °C (239–275 °F; 388–408 K) (239–275 °F)|
Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
Polyethylene (abbreviated PE) or polyethene (IUPAC name polyethene or poly(methylene)) is the most common plastic. The annual global production is around 80 million tonnes. Its primary use is in packaging (plastic bags, plastic films, geomembranes, containers including bottles, etc.). Many kinds of polyethylene are known, with most having the chemical formula (C2H4)n. Thus, PE is usually a mixture of similar polymers of ethylene with various values of n.
