LDPE resin/virgin LDPE/LDPE granules

الوصف

LDPE (the first grade of polyethylene) is a thermoplasticmade from the monomerethylene. It contains the chemical elements carbon and hydrogen. 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 acids, alcohols, bases and esters, good resistance (minor attack) to aldehydes, ketones and vegetable oils, limited resistance (moderate attack suitable for short-term use only) to aliphaticand aromatichydrocarbons, mineral oils, and oxidizing agents, and poor resistance, and not recommended for use with halogenated hydrocarbons.
