This product is made of glass wool, and the material is heated by the heating and curing process. Its bulk density is lighter than the sheet metal, has the good rebound, the price is cheap, the construction is convenient.
The centrifugal glass wool felt is a material which is suitable for large area laying. In addition to maintaining the characteristics of heat preservation and insulation, it also has a very excellent shock absorption, sound absorption characteristics, especially for medium and low frequency and all kinds of vibration and noise have good absorption effect, is conducive to reduce noise pollution and improve the working environment.
This material can be used in the construction of arbitrary cutting, mainly used in building interior, noise elimination system, transportation equipment, refrigeration equipment, household appliances, shock absorption, sound absorption, noise reduction, the effect is very ideal.
Aluminum foil with a glass wool felt, but also has a strong ability to heat radiation, high temperature workshop, control room, engine room wall, compartment and flat top of the lining material.
