Final answer:
HDPE stands for high-density polyethylene, which has a dense, linear molecular structure contributing to its high tensile strength and is widely used in sturdy product packaging and containers.
Step-by-step explanation:
HDPE stands for high-density polyethylene. HDPE is characterized by its high density and low degree of branching. Its linear polymer chains are able to pack tightly together, leading to strong intermolecular forces, which contribute to high tensile strength. These properties make HDPE an ideal material for many applications, such as containers for milk, detergent, as well as pipes and toys. With a density greater or equal to 0.941 g/cm³, HDPE's structure contrasts with that of LDPE (low-density polyethylene), which has a much higher degree of branching and is used for products requiring increased flexibility, like plastic bags.
In summary, the correct answer to the multiple-choice question is A) high-density polyethylene. HDPE has become prevalent in the manufacturing sector, with global consumption figures having surpassed 30 million tons at one point. Its strength and durability are attributed to its mostly linear molecular structure and higher density compared to other types of polyethylene.
