Swellable Yarn Ultrabloc SY

Super absorbent polymer yarn for wire and cable products
Coats Ultrabloc SY is a water-swellable polymer yarn that can resist salt and sea water, and withstand extreme temperatures.

Ideal for dry blocking in wire and cable products, Ultrabloc SY is carefully manufactured on state-of-the-art spinning equipment to ensure a smooth and consistent surface. This method of manufacture also prevents micro or macrobending. Its uncoated finish helps to reduce shedding or dusting during cable manufacturing, which improves productivity.

Furthermore Ultrabloc SY decreases cable prep time and eliminates the need for potentially hazardous solvents which also results in less requirement of consumable materials and a cleaner work environment.
