Description

Low-Density Polyethylene (LDPE) LDPE, the first of the polyethylene to be developed, is characterized by good toughness and flexibility, relatively low heat resistance, low-temperature impact resistance, and clarity in film form. Like all polyethylene grades, LDPE has good resistance to chemical attack. At room temperature, it is insoluble in most organic solvents but is attacked by strong oxidizing acids. At higher temperatures, it becomes increasingly more susceptible to attack by aromatic, chlorinated and aliphatic hydrocarbons.

Polyethylene is susceptible to stress cracking when exposed to ultraviolet and some chemicals. Wetting agents, such as detergents, accelerate stress cracking. Some copolymers of LDPE are available with improved stress-crack resistance.
