Aluminum Silicate Needle Blanket
The thermal conductivity of the aluminum silicate needle blanket is slightly larger than that of air. Because the aluminum silicate blanket is composed of a mixed design of solid fibers and air, the porosity is as high as more than 90%. A lot of low thermal conductivity air is filled in the pores and destroys the The continuous network layout of solid molecules results in excellent thermal insulation properties. Moreover, the smaller the pore diameter and the greater the number of closed pores cut by solid fibers along the direction of heat flow, the better the thermal insulation performance of

Moreover, the smaller the pore diameter and the greater the number of closed pores cut by solid fibers along the direction of heat flow, the better the thermal insulation performance of the high-aluminum aluminum silicate needle-punched blanket.
Features
1. High Temperature Resistance:These blankets can withstand extremely high temperatures, typically up to 2300°F (1260°C) or higher.
2.Lightweight and Flexible: Aluminum silicate needle-punched blankets are lightweight and flexible, allowing for easy handling, cutting, and installation in various shapes and sizes.
3.Easy Installation:These blankets are easy to cut, shape, and install, allowing for quick and efficient insulation of various industrial equipment, furnaces, boilers, and pipes.
