SUNTHERM 1600C Refractory Fiber Board

Product Description

SUNTHERM 1600C Refractory Fiber Board is a premium refractory insulation panel manufactured via an advanced wet‑forming process. It is made from high‑purity 1600‑grade polycrystalline alumina fiber, bonded with a carefully balanced blend of inorganic and organic additives to deliver consistent density, superior strength, and excellent dimensional uniformity.

 

Built to withstand extreme heat, this board maintains outstanding thermal stability at continuous service temperatures up to 1450°C. Its inherently low thermal conductivity and high insulating efficiency translate into marked energy savings, reduced heat leakage, and shorter process cycles-directly lowering your operational expenses.

 

Well suited for high‑temperature kilns, industrial furnaces, incinerators, and petrochemical heaters, SUNTHERM 1600C brings together robust mechanical integrity, exceptional insulation, and long‑term chemical resilience in a single advanced ceramic fiber solution-reliable protection where it matters most.

 

Product Features

Ultra-high temperature resistance (long-term 1450°C, higher short-term), low thermal conductivity via microporous structure for energy savings, high purity (Al₂O₃ ≥95%, no volatile emissions), excellent thermal stability and shock resistance, good mechanical strength (high compressive/flexural strength, no breakage/slagging), precise dimensions (smooth, uniform, easy to machine), broad corrosion resistance (except HF/strong alkalis), and low heat capacity for rapid thermal cycling and enhanced productivity.
