Semi-conductive cushion water blocking tape is a high-performance water-blocking material specifically designed for cables and optical cables. Made with high-strength non-woven fabric and water-absorbent swelling materials, it offers excellent semi-conductivity and water-blocking properties. It provides mechanical cushioning within the cable while rapidly expanding upon contact with water, forming a reliable barrier to protect cable performance and lifespan.
