PP is described as which of the following properties?

PP is described as which of the following properties?

• A. Fatigue and chemical resistant e.g. rope
• B. Very stiff and brittle
• C. Highly flammable
• D. Not resistant to chemicals

Answer: (A)

Polypropylene is known for its ability to endure repeated flexing and its resistance to many chemicals. This combination means it won’t crack or fail when bent or pulled repeatedly, which is why it’s used for rope and other flexible, durable products. Its chemical stability lets it withstand exposure to many solvents, acids, and bases. It isn’t characteristically stiff and brittle—it's fairly tough and flexible—which is why that description doesn’t fit. It isn’t typically described as highly flammable, and it does resist chemicals rather than being non-resistant. So the statement describing fatigue and chemical resistance fits polypropylene best.
