Why High-Temperature Insulation Matters in Aluminum Electrolysis

For aluminum producers, energy efficiency isn’t just a goal—it’s a survival strategy. In modern electrolytic cells, up to 15% of total energy input is lost through poor insulation. That’s where 蛭石保温板 (vermiculite insulation board) comes in—not as a passive material, but as an active performance enhancer.

The Science Behind the Performance

Engineered for temperatures up to 1050°C, our vermiculite insulation board uses a proprietary high-temperature purification process that removes organic contaminants during manufacturing. This results in:

• Lower thermal conductivity: Down to 0.045 W/m·K (vs. 0.07–0.12 W/m·K for traditional materials)
• Improved structural integrity: 30% higher compressive strength at operating temps
• Reduced maintenance frequency: From annual inspections to biannual or less

These aren’t theoretical benefits—they’re backed by real-world data from over 50 industrial installations across China, Europe, and the Middle East.

Real Results, Real Savings

A major aluminum smelter in Saudi Arabia reported a 6.2% improvement in electrical efficiency after switching to this insulation system. Over one year, that translated into:

That’s not just cost savings—it’s a shift toward sustainable operations. And it’s exactly what forward-thinking aluminum manufacturers need to stay competitive globally.

“We didn’t expect such a dramatic change in cell efficiency. It felt like we had upgraded our entire production line without touching the electrolysis equipment.” — Plant Manager, UAE-based Smelter
