As power grids expand across offshore, urban, and underground environments, reliable MV cables are more critical than ever. Chase Corporation’s new Chase BlH₂Ock® High-Flow (A162HF) delivers 35% higher flow, lower processing temps, and faster line speeds, helping manufacturers reduce downtime and boost reliability in demanding cable applications.
Chase Corporation, known globally for its Chase BlH₂Ock® A162A water-blocking
compound, has launched a next-generation solution: Chase BlH₂Ock® High-Flow
(A162HF). With a 35% higher melt index and lower processing temperatures, this innovative
strand-block material improves line speed, reduces downtime, and maintains the same
compliance with global MV cable standards as traditional Chase BIH20ck — especially vital
for undersea and underground power transmission.
Why This Matters Now
As the global grid expands through urban tunnels, offshore wind farms, and remote
infrastructure, reliable, long-life MV cables are more critical than ever. Water ingress
remains a top cause of cable failure — and in harsh, wet environments, failure isn’t an option.
That’s why Chase Corporation re-engineered its trusted strand-block technology. The result:
Chase BlH₂Ock® High-Flow, designed for next-level throughput and performance.
• Water ingress into stranded conductors causes microscopic cracks (water-treeing),
reducing cable life from 30–40 years to as little as 8–12.
• Traditional strand-block compounds can limit line speed, clog pumps, or stress
tooling at high temperatures.
| Feature | Benefit to Manufacturers |
