Laurel’s Polycrystalline Fiber Boards are rigid, extremely high-temperature insulation panels designed for precision applications requiring minimal shrinkage and maximum structural reliability up to 1600°C. Polycrystalline Fiber Boards maintain dimensional accuracy under severe thermal cycling and offer excellent resistance to chemical attack. Suitable for furnace linings, burner components, thermal barriers, and high-temperature processing equipment.

Polycrystalline Fiber Board from Laurel Refractory is engineered for high-strength, high-density insulation applications requiring extreme temperature resistance. Produced through precision forming technology, each Polycrystalline Fiber Board provides excellent mechanical stability, low thermal conductivity, and long service life.

Laurel Refractory’s factory maintains strict quality control to ensure every Polycrystalline Fiber Board meets engineering-grade performance expectations, supporting large procurement programs and international projects.
