Which of the following is not a property of Polycarbonate plastic?

Polycarbonate plastic is known for several key properties that make it a popular choice in various applications. It is indeed flexible, impact-resistant, and transparent.

The flexibility of polycarbonate allows it to withstand bending and twisting without breaking, making it suitable for applications like safety goggles and other protective gear. Its impact resistance is particularly noteworthy; polycarbonate is significantly more resistant to impacts than many other plastics, which is why it's often used in applications like eyewear lenses and protective shields. Furthermore, its transparent nature allows for high optical clarity, which is important in products needing visibility, like light covers or signage.

The reason brittleness is not a property associated with polycarbonate is that it is engineered to be strong and resilient. While some plastics can be brittle and prone to cracking, polycarbonate is specifically designed to endure stress and impact without shattering, which sets it apart from materials that exhibit brittleness. Thus, identifying brittleness as a non-property of polycarbonate highlights its unique advantages and essential features.
