These lines are constructed from high tech fibers such as Dyneema, Vectran, Technora, and PBO. They are used in multipart purchase systems or as a wire replacement. These have very high breaking strength, low stretch, but not used in applications where it will be held in the hand.
Super light with no water uptake. the "MAX" process adds strength and removes stretch. This line has virtually no creep so Excel D12 MAX is a great lightweight fiber option for standing rigging, removing weight from the rig. Also works great for highly loaded control line purchases. Almost zero creep and elongation at working loads, UV resistant.
12-strand single braid of 100% Vectran. Highest strength, lowest stretch and creep of any other 12-strand. V-12 is treated with a proprietary Marine-Tech coating for improved abrasion resistance.
