Product Description

This Fiberglass Needle Felt is made of glass fiber. This material not only has the advantages of high temperature resistance, corrosion resistance, dimensional stability, minimal elongation and shrinkage, and high strength, but also has the features of three-dimensional micro-porous structure, high porosity, and low resistance to gas filtration. When the sound waves invade the glass fiber cotton, due to the friction and the size of the cavitation, the sound absorption rate is as high as 90% or more. Therefore, this needle felt is a good way to prevent noise interference. In addition, compared with other insulation materials, the Fiberglass Needle Felt is the light and most flexible. If installed on the machine, this felt can reduce its weight and vibration load. Specification
