Water Blocking Yarns

Fibure offers high-quality water blocking yarn that is specifically designed for cables to prevent water penetration. Our water blocking yarn eliminates the need for flooding gels and tapes in fiber optic cables. It swells rapidly upon contact with water, forming gels that effectively halt further water flow into the cable jacket. With its exceptional water blocking properties, our yarn ensures optimal cable protection and reliability. Additionally, it boasts excellent abrasion resistance and easy handling, making it a preferred choice for cable manufacturers. Trust Fibure for water blocking yarn that delivers fast swelling, high tensile strength, and reliable water blocking performance.
