What is one property of LDPE?

One property of LDPE, or Low-Density Polyethylene, is that it is recyclable. LDPE is commonly identified by recycling code 4 and is widely used in products like plastic bags, containers, and various packaging materials. Its chemical structure allows it to be melted down and reformed into new products, making it an environmentally friendlier option compared to some other plastics that do not easily undergo recycling processes. The emphasis on sustainability and recycling is increasingly important in modern material science and engineering, highlighting the utility and versatility of LDPE in a circular economy.

In contrast, the other options do not accurately describe this material. LDPE is not categorized as very hard; rather, it is known for its flexibility and toughness. Furthermore, while it is recyclable, it is not correct to state that it is non-recyclable. Lastly, LDPE serves as a decent insulator rather than being classified as a poor insulator, which is due to its properties that limit the conduction of electricity and heat.
