Flexible plastic pipes are made of___________________?
Correct answer: B. Low density polyethylene (LDPE)
- A. High density polyethylene (HDPE)
- B. Low density polyethylene (LDPE)
- C. Polypropylene
- D. Unsaturated polyester
Explanation
LDPE has a highly branched molecular structure, giving it flexibility and allowing it to be formed into flexible pipes and tubing. HDPE is more linear and rigid, so it is preferred where greater stiffness is needed.
