Product Overview

Description

Low-density polyethylene (LDPE)

 

LDPE (the first grade of polyethylene) is a thermoplasticmade from the monomerethylene. It contains the chemical elements carbon andhydrogen. It is characterized by its short and long chain branching which gives it good clarity and processability although it does not have the strength properties of the other PEs. So, its intermolecular forces are weaker, its tensile strength is lower, and its resilienceis higher. Also, since its molecules are less tightly packed and less crystalline because of the side branches, its densityis lower.

 

LDPE has Excellent resistance (no attack) to dilute and concentrated acidsalcoholsbases and esters, good resistance (minor attack) toaldehydesketones and vegetable oils, limited resistance (moderate attack suitable for short-term use only) to aliphaticandaromatichydrocarbonsmineral oils, and oxidizing agents, and poor resistance, and not recommended for use with halogenated hydrocarbons.
