Ceramic Fiber Blanket

Classification temperature is the laboratory grading point at which a sample stays within a defined linear shrinkage after 24 hours. It is a grade label, not a service limit. Working temperature is the continuous-use ceiling in a real furnace atmosphere, and that is the number you should design to. For example, our ST grade is classified at 1260°C but is rated for continuous service at 1050°C.

For a continuous 1100°C hot face, specify HP as a minimum (working temperature up to 1100°C) or HA (up to 1200°C) if the furnace cycles frequently or runs close to its limit. Specifying ST for an 1100°C furnace accelerates shrinkage and shortens lining life.

Standard supply is 96 kg/m³ for the COM grade and 128 kg/m³ for ST, HP, HA and HZ. Higher density improves resistance to gas erosion and mechanical damage, so it suits high-velocity flue gas or linings that get handled. Lower density reduces heat storage and material cost where the lining is protected.

Standard rolls are 7200 × 610 mm in thicknesses from 10 mm to 50 mm. Other widths, thicknesses and cut-to-length formats can be produced to your drawing.

No. Each blanket is needle-punched on both sides, so its strength comes from mechanical fibre interlocking rather than an organic binder. That means no smoke or odour during first heat-up and no loss of strength once any organic content burns out.

MOQ is 1 ton per specification for ceramic fiber blanket. Standard products are typically delivered within 15-20 days; custom or large orders take 30-60 days.
