Which among the following statements about HDP is NOT true?

Options

  1. AIt melts at low temperature than LDP.
  2. BIt is manufactured by applying low pressure than LDP manufacture process.
  3. CIt is stiffer than LDP.
  4. 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
