Question

Conveyor belt is manufactured from

• A. buna-S
• B. neoprene
• C. PVC
• D. teflon
• E. glyptal

Answer 1

The Correct Option is B

Conveyor belts are typically made from durable synthetic materials that provide good strength and resistance to wear and tear. Among the options provided, \(\textbf{neoprene}\) is commonly used for manufacturing conveyor belts due to its excellent flexibility, resistance to oils, and wear resistance. \(\textbf{Buna-S}\) is used for making other rubber products, \(\textbf{PVC}\) is used in a variety of applications but not as commonly in conveyor belts, and \(\textbf{teflon}\) is used in non-stick applications rather than conveyor belts.

The correct option is (B) : neoprene

Answer 2

Conveyor belts need to be strong, flexible, and resistant to wear and tear. Among the options provided, neoprene is the most suitable material for manufacturing conveyor belts.

Here's why:

• Neoprene (polychloroprene) exhibits excellent tensile strength, abrasion resistance, and resistance to oils, chemicals, and heat.
• Buna-S (styrene-butadiene rubber) has good abrasion resistance but lower resistance to oils and chemicals than neoprene.
• PVC (polyvinyl chloride) is relatively rigid and not as flexible or abrasion-resistant as neoprene.
• Teflon (polytetrafluoroethylene) has excellent chemical resistance and a low coefficient of friction but lacks the strength and flexibility needed for conveyor belts.
• Glyptal is a thermosetting resin used for coatings and moldings but is not suitable for conveyor belts.

Therefore, the answer is neoprene.
