Fire-Resistant Silicone Ceramic Fiber Blanket
Fire-resistant silicone is heat-resistant to temperatures exceeding 1200°C. It is made from high-strength ceramic fibers through a double-sided needle-punching process. This process does not contain any binders or other ingredients. The enhanced needle-punching process improves the fiber interweaving and the blanket's delamination resistance, while maintaining excellent tensile strength without compromising flexibility. The fire-resistant silicone ceramic fiber blanket exhibits excellent chemical stability and is impervious to most chemicals except hydrofluoric acid, phosphoric acid, and strong alkalis, resulting in excellent high-temperature and fire-resistant properties.
Product Features:
1. Low heat capacity and low thermal conductivity.
2. Excellent chemical stability.
3. Ultra-high temperature resistance and stable thermal insulation.
4. Fireproof and non-combustible.
5. Free of binders and corrosive substances.
Applications:
Aerospace, building and construction, battery energy storage, wearable devices, home appliances, ovens, industrial equipment, industrial kilns, automotive and RV equipment, and pipe insulation.

A seven-zone mesh belt furnace running at 1120 °C can hold ±3 °C across the belt and still ship parts with inconsistent hardness, because the dew point in the delubrication zone drifted after the belt speed was raised. That is the nature of powder metallurgy: the furnace is not a box that gets hot, it is a chemical reactor with a conveyor attached. The short answer: select a powder metallurgy furnace by the process window it must hold — delubrication profile, atmosphere quality, sintering tempe...
