Swellcoat™ Water Blocking & Absorbing Yarn
Our patented Swellcoat™ coatings are engineered to be the last line of defense against the damaging effects of water penetration in cable applications. Formulated to process cleanly and efficiently, they eliminate the need to deal with messy gels.
Swellcoat™ impregnated fibers efficiently introduce SAP (Super Absorbent Polymer) into fiber optic cable binders, fillers, and buffer threads to prevent moisture ingress in dry cable design by creating a stable gel, absorbing up to 100x their weight.
Swellcoat™ Blocker yarns provide water-blocked strength reinforcements for dry cable designs and can absorb up to 15x their weight.
Our water blocking and absorbing yarn and flat, uncoated binder yarns are supplied on a variety of colored, embossed and/or slit cardboard tubes to meet your equipment needs. Plastic, wood, or metal reels are also available. Our precision wound packages yield the greatest length per package and ensure solid package stability and minimum ballooning at speeds reaching 4000 rpm's.
