Premium Durability Boot Laces
• Black Laces & Black Metal Aglets
• Perfect for those in welding, concrete cutting, wildland firefighting, construction, and any other heavy duty work.
High Tensile Strength - Strong and light, these laces are 8 times stronger than steel and 3 times stronger than fiberglass, polyester or nylon yarns.
Fatigue Resistance - Shows little loss of strength even during repeated abrasion, flexing and stretching.
Dimensional Stability - Stiff and highly oriented molecular structure leads to a high modulus of elasticity, low creep and low stress relaxation. Low thermal shrinkage, i.e., excellent dimensional stability.
Heat Resistance - Thermal decomposition threshold of 930ºF. Can be used at 390ºF for long periods. At 480ºF, it maintains more than half of its room-temperature tensile strength.
Chemical Resistance - Highly resistant to acids, alkalis and organic solvents; not vulnerable to damage caused by steam or sea water.
