Polypropylene rope floats and has what property?

Polypropylene rope floats and has what property?

• A. High strength in wet conditions
• B. Floats and good chemical resistance
• C. Low melting point
• D. Hard to knot

Answer: (B)

Polypropylene rope floats because its density is lower than water, and it doesn't readily absorb moisture, so it stays buoyant even when wet. It also has good chemical resistance thanks to its non-polar hydrocarbon structure, making it resistant to many acids, bases, and solvents. This combination—buoyancy in water and resistance to chemical exposure—is what makes polypropylene rope particularly useful in marine and chemical environments. While it can have a low melting point and may be slippery in knots, those traits are less defining than its ability to float and resist chemicals.
