Water blocking swellable soft yarns
Soft Super Absorbing Fiber (SAF™) is the key component in Water Blocking Swellable SAF™ Soft Yarns, which are usually blended with other synthetic fibers such as polyester, nylon, to add strength or additional functionality. The SAF™ content does not shed when the yarns are being cut and spliced for use. Water Blocking Swellable SAF™ Soft Yarns protect power, telecommunication and special cables by rapidly absorbing water at the point of damage. Upon contact with water, the yarn will swell and form an impermeable barrier.
Key features
- Rapid water absorption. Absorbs 200x own weight.
- High swelling speed up to 75 ml/g/1st min.
- High tensile strength and resistant to operations. Highly temperature stable.
- Easy integration and processing. Dry diameter from 0.5mm up to 30mm.
- Spooling forms: SAF™ Yarns are supplied on cylindrical or cone bobbins.
