In 2025, global Semi-conductive Buffer Water-blocking Tape production reached approximately 26,683 tons with an average global market price of around US$ 7,569 per ton. The production capacity for Semi-conductive Buffer Water-blocking Tape in 2025 was approximately 30000 tons. The typical gross profit margin for Semi-conductive Buffer Water-blocking Tape is between 20% and 40%.

Semi-conductive Buffer Water-blocking Tape is a functional composite tape used in medium-, high- and extra-high-voltage power cables, typically composed of a semi-conductive nonwoven substrate, super-absorbent polymer (SAP), and conductive carbon-based additives. It is applied around the conductor or insulation shield layer to provide electric field homogenization, mechanical buffering, and both radial and longitudinal water-blocking performance. The tape maintains stable volume resistivity to ensure electrical continuity within the cable shielding system, while rapidly swelling upon water ingress to prevent moisture propagation along the cable length, thereby reducing water-tree aging and enhancing long-term cable reliability and service life. It is widely used in underground cables, submarine cables, and high-reliability power transmission and distribution systems.

The market for Semi-conductive Buffer Water-blocking Tape is primarily driven by demand from medium- and high-voltage power cables, extra-high-voltage transmission projects, submarine cables, and urban underground power grid construction, closely linked to global grid modernization, renewable energy integration, and rising reliability requirements in power transmission systems. As cable systems move toward higher voltage levels, longer transmission distances, and more complex installation environments, demand continues to increase for materials offering superior water-blocking performance, stable electrical properties, and long-term aging resistance. Regionally, Asiaparticularly Chinarepresents the largest production and consumption base, while Europe maintains strong technical barriers in high-end and EHV applications. Overall, the market is characterized by high technical entry thresholds, long qualification cycles, and strong customer stickiness, with supply concentrated among a limited number of specialized cable material manufacturers.
