Tufflex^® Sinking

Polyester & Copolymer Blend, 3- & 8-Strand

Tufflex® Sinking Ropes are crafted from a unique blend of high-strength polyester and copolymer fibers, offering a balanced combination of durability, flexibility, and performance. This specialized construction ensures excellent wear resistance, making the rope ideal for demanding marine and industrial applications where long service life is essential. Its sinking property adds functional value in environments where buoyant ropes are unsuitable, such as underwater applications: subsea, fishing and offshore applications.
