Question

what do you mean by high density polythene explain briefly​

Answer 1

Answer:

HDPE is a hydrocarbon polymer prepared from ethylene/petroleum by a catalytic process. It is a kind of thermoplastic which is famous for its tensile strength. Its unique properties can stand high temperatures. ... HDPE pipes are used to both carry potable water and hazardous waste.

Answer 2

Answer:

Catalytic polymerization of ethene at 300-350 K at atmospheric pressure produce linear polymer chains. Linear branch change give more closely packed structure.

The polythene consisting of linear and branched chain is called high density polythene (HDPE).

High density polythene is -

• Chemically inert
• Relative more tough and hard with high tensile strength.

HDPE is prepared by the addition polymerization of ethene is generally used for manufacturing containers, pipes, bottles and laboratory ware.
