Question

Differentiate between LDP and HDP

Answer 1

The high-density polyethylene is more crystalline than low-density polyethylene because it contains fewer branches. ... LDPE is softer, more flexable and melts at lower temperatures than HDPE.

Answer 2

Answer:

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. LDP is mainly used in preparation of pipes for agriculture, irrigation and domestic water line connections. HDP is used in manufacture of toys and other household articles like bucket, bottles, etc.
