Question

Polyvinyl chloride is

• A. Thermoplastics
• B. Thermosetting
• C. Elastomers
• D. None of the above

Hint:

PVC is commonly found in two forms: rigid (RPVC) for pipes and profiles, and flexible (FPVC) for applications like electrical cables and medical tubing.

Answer 1

The Correct Option is A

Polyvinyl chloride (PVC) is one of the most widely used synthetic polymers due to its versatility. It can be manufactured in both rigid and flexible forms, making it suitable for applications ranging from pipes to flooring and medical equipment. Step 1: Classifying PVC - Thermoplastics: These materials soften when heated and harden when cooled. They are recyclable and can be molded into different shapes. PVC is classified as a thermoplastic due to its ability to soften under heat and be re-molded into various forms. - Thermosetting Plastics: These polymers undergo a permanent curing process and cannot be remelted. - Elastomers: These are highly elastic materials, like rubber, which can stretch significantly and return to their original shape.


Step 2: Conclusion Since PVC can be molded and remelted, it is a thermoplastic, making option (A) the correct answer.
