Manila is the strongest natural fiber rope. It has great knotting ability but low elasticity. Being a natural fiber, manila rope is susceptible to water, chemicals & oils. It is best used in dry conditions. Rope will mildew, rot and lose strength if exposed to moisture and will deteriorate if exposed to chemicals. Unlike other ropes, manila is resistant to heat. Short exposure to heated wires or equipment will not melt the rope. Exposure to heat is not suggested for long periods of time. It will burn if exposed to high temperatures.
