LOW LINEAR DENSITY POLYETHYLENE (LLDPE)
DOW CHEMICAL LOW LINEAR DENSITY POLYETHYLENE PE DOW 2517NT (LLDPE)
Dow Chemical High Density Polyethylene PE Dow 2517NT
Polyethylene is among the lowest density plastics and therefore is one of the lowest cost per cubic measure compared to other plastics. Low density polyethylene has good toughness, excellent electrical properties, and chemical resistance, good low temperature brittleness and very low water absorption. Polyethylene is essentially inert, unaffected by strong and weak acids, alkalies, detergents, alcohols, and ketones. Polyethylene has low tensile strength and is subject to considerable creep and stress relaxation under load. Polyethylene will swell with chlorinated and aromatic hydrocarbons including gasoline and oils.
