What is the density of aluminum silicate needle punched blanket?

Dec 11, 2025

What is the density of aluminum silicate needle punched blanket? Aluminum silicate needle punched blanket is a commonly used insulation material. The density of aluminum silicate needle punched blanket refers to the mass per unit volume, which affects the insulation performance, compressive strength, and thermal conductivity of the product. Therefore, it is important to understand the density range of aluminum silicate needle punched blankets. Because its density is one of the important technical parameters. The higher the density, the better the insulation performance and compressive strength of the product, but the thermal conductivity will correspondingly increase. Therefore, choosing the appropriate density is crucial for ensuring the performance of aluminum silicate needle punched blankets.


Technically speaking, the density of aluminum silicate needle punched blanket is significantly affected by the needle punching process. The dense needle punching process can increase the bonding force between fibers, thereby improving density, enhancing the structural strength and insulation performance of materials. On the contrary, the loose needle punching process can lead to a decrease in density and a lighter material, but may sacrifice the insulation effect to some extent.

The density parameter table of aluminum silicate needle punched blanket is as follows:


Aluminum silicate needled blanket is a new type of environmental protection material, which is characterized by excellent sound insulation, sound absorption, heat preservation, fire prevention and other properties, as well as good corrosion resistance and aging resistance, and is widely used in construction, ships, locomotives, aerospace and other fields. It has broad application prospects, and its national standard parameters are constantly being improved and adjusted to better meet market demand.
