Which among the following statements about HDP is NOT true?
Options
- AIt melts at low temperature than LDP.
- BIt is manufactured by applying low pressure than LDP manufacture process.
- CIt is stiffer than LDP.
- DIt is crystalline.
Correct answer
A. It melts at low temperature than LDP.
Step-by-step solution
High-density polyethylene (HDPE) It is obtained by coordination polymerization using Ziegler-Natta catalyst. It has a higher melting point (130^ C ) and higher density (0.97 ~g ~cm ⁻³ ) . It has a linear polymer chain and hence has greater strength and heat resistance. Polyethylene (low density, m. p. 110^ C
