K26 insulating fire brick is a kind of mullite insulation brick. It is characterized by high porosity, low bulk density and low thermal conductivity. Kerui K26 insulation brick has a porous structure (porosity is usually 40% to 85%) and excellent thermal insulation performance. Therefore, it is suitable for the insulation layer and heat insulation layer of various industrial kilns.

Product Features of K26 Insulating Fire Brick
- Low thermal conductivity: low thermal conductivity, good thermal insulation effect.
- High temperature resistance: refractoriness is as high as 1430℃(2606℉) and can withstand extreme high temperature environments.
- Resistance to thermal shock: it can also effectively resist thermal stress caused by rapid temperature changes.
- High strength: it can maintain high mechanical strength even under high temperature conditions.
- Foam-like structure: the pores of Kerui mullite insulating brick is evenly distributed. This enhances its thermal insulation effect.
- Accurate size: this speeds up masonry and reduces the use of refractory mortar. This can also ensure the strength and stability of the insulation brick masonry.
- Green and environmentally friendly: k26 mullite insulation bricks are non-toxic and non-corrosive.
