It is mainly used for high temperature operation, special ship,
electrical engineering, marine operations, various types of slings,
suspension, military research and other fields.
Aramid has all of the properties you want in a speargun line. It's
ultra high strength, ultra low stretch and superior knot retention
mean that once tightened your constictor knot will stay tight.
Avoid the problems of knot creep or stretch inherent in other high
performance fibers. This line is excellent for a multitude of
applications including model rocketry and fire poi. The general
characteristics of aramid are: High Modulus, High LASE (Load At
Specified Elongation), High Tensile Strength at Low Weight, Low
Elongation to Break High Modulus, (Structural Rigidity), Low
Electrical Conductivity, High Chemical Resistance, Low Thermal
Shrinkage, High Toughness (Work~To~Break), Excellent Dimensional
Stability, High Cut Resistance, Flame Resistant,
