LIST-I LIST-II A. PU I. Oil seal B. UPVC II. Tyre C. NBR III. Shoe-sole D. NR IV. Window-panel
Choose the correct answer from the options given below:
The question requires matching specific materials from LIST-I with their corresponding applications listed in LIST-II.
PUI often denotes Polyurethane. This versatile polymer is known for its durability and is commonly used in applications requiring wear resistance and flexibility. A primary use is in manufacturing III. Shoe-sole, providing cushioning and support.
UPVC stands for Unplasticized Polyvinyl Chloride. It is a rigid and robust plastic material valued for its resistance to weathering and corrosion. Its typical use in construction is for components like IV. Window-panel frames and pipes.
NBR refers to Nitrile Butadiene Rubber. This synthetic rubber exhibits excellent resistance to oils, fuels, and certain chemicals. Consequently, it is widely utilized in producing components that require fluid resistance, such as I. Oil seal.
NR is the abbreviation for Natural Rubber. Valued for its high elasticity, resilience, and tensile strength, natural rubber is a key material in the manufacturing of tires. The appropriate match is II. Tyre.
Based on the analysis of each material and its common applications:
This leads to the correct combination: A-III, B-IV, C-I, D-II.
