Which statement about ABS is true?

Which statement about ABS is true?

• A. Thermoplastic with durability, weather and chemical resistance; good impact resistance; rigid.
• B. Brittle and soft due to low impact resistance.
• C. Only used for electronic conductors.
• D. Transparent glass substitute.

Answer: (A)

ABS is a tough, rigid thermoplastic made from acrylonitrile, butadiene and styrene. The acrylonitrile component gives chemical and heat resistance, the butadiene provides toughness and impact resistance, and the styrene adds rigidity and ease of processing. This combination makes ABS durable, able to resist weathering and many chemicals, and capable of absorbing impacts without cracking. That’s why it’s widely used for sturdy housings, automotive parts, toys, and similar items. The other statements don’t fit ABS well. It isn’t brittle or soft; its strength and impact resistance are key traits. It isn’t used only for electronic conductors—it's an insulating polymer used in many non-electronic applications. And it isn’t a transparent glass substitute, since ABS is typically opaque rather than transparent.
