* Breaking elongation 2.8-3.9excellent relaxation fatigue strength,1000 times thaat of steel cable and nylon rope
* Density of 0.97 g/m³,less than water,float in water,soft,con- venient plug
* At room temperature,the industrial concentrated acid resis- tance,alkali,oxidant
* Fatigue resistance is strong.the rope load 40%50% cyclic loading 100000 times eventually breaking strength is not reduced
* Resistance to low temperature: 43 degroes below zero porfor- manceis not reduced
