YL Centrifugal Glass Wool
Formaldehyde-free glass wool is made of natural minerals such as quartz sand, dolomite, borax and other inorganic materials, mixed according to the specific process formula ratio requirements, after 1360 ℃ high temperature hot melt, using advanced centrifugal fiber forming technology to make glass wool felt and glass Cotton board and other products.
Product advantages
● Insulation and sound absorption
The characteristics of low content of glass wool slag ball, slender fiber,
etc., have excellent thermal insulation, sound absorption and noise reduction effect.
● Good thermal stability
Glass wool has good high temperature thermal stability, durability and resistance to high temperature shrinkage
It can maintain safety, stability and high efficiency for a long time within the recommended temperature range.
● Different durable moisture resistance
Hydrophobicity refers to the ability of a material to resist water penetration. The glass wool reaches a water repellency rate of not less than 98%, making it more
Continuous and stable insulation performance.
● Good fire performance
Tested according to GB8624-2012 standard, glass wool is non-combustible A grade material
● No poison
Liquid glass wool does not contain formaldehyde, asbestos, no mold, and no microbial growth foundation.
Product application
Insulated glass wool is used for thermal insulation of building steel structures, wall insulation, pipeline insulation, etc., as well as central air conditioning ducts, indoor partitions, thermal insulation and sound insulation of train cars, etc. to achieve good thermal insulation, sound absorption and impulsiveness. Moreover, this product has light texture, corrosion resistance, non-combustibility and other characteristics, which are new green energy-saving products and are widely distributed in the market.
