Therefore, LDP is used in producing extruded films, sheets, mainly for packaging and household uses like in preparation of squeeze bottles, attractive containers, etc. where low tensile strength and flexibility are required. On the other hand, HDP is a linear polymer of ethene with closely packed polymeric chains.

HDP (high-density polymer) consists of a linear molecule and has a high density due to close packing. It is quite hard, tougher and has greater tensile strength than LDP. It is a translucent polymer. The LDP (low-density polymer) has a highly branched structure. Due to branching, the molecules do not pack well.

The low-density polythene (LDP) is obtained through the free radical addition and H-atom abstraction has highly branched structure.

Apr 9, 2019 · 1) LDP is low density polyethylene and HDP is high density polyethylene. 2) LDP is density a branched polymer with low density due to chains are loosely held and HDP is a linear polymer with density due to close packing. 3) HDP is much stiffer than LDP and has high tensile strength and hardness.

Dec 4, 2021 · HDP (High density polythene) consists of linear chains of monomer units that are closely packed in space. That is why its density is high as compared to LDP (Low density polythene) in which the monomer chains are branched and are loosely packed.

Oct 19, 2021 · LDP is a branched polymer with low density due to chains are loosely held and HDP is a linear polymer with density due to close packing. HDP is much stiffer than LDP and has high tensile strength and hardness. LDP is mainly used in preparation of pipes for agriculture, irrigation and domestic water line connections.

Nov 18, 2021 · Properties of HDP : HDP is crystalline, melting point in the range of 144 – 150 °C. It is much stiffer than LDP and has high tensile strength and hardness. It is more resistant to chemicals than LDP. Uses of HDP : HDP is used in manufacture of toys and other household articles like buckets, dustbins, bottles, pipes, etc.

What is meant by LDP and HDP? Mention the basic difference between the same with suitable examples.

LDP obtained through the free radical addition and H-atom abstraction has highly branched structure. Due to this branching, the density of LDP becomes low. Whereas HDP is obtained when addition polymerisation of ethene takes place in a hydrocarbon solvent in the presence of a catalyst such as triethylaluminium and titanium tetrachloride.

Low density polythene and high density polythene, both are polymers of ethene but there is marked difference in their properties. Explain. 1. It is obtained by the polymerisation of ethene …
