Glass wool is a common functional material, with thermal insulation, sound insulation, fire retardant, corrosion resistance and other properties, is widely used in construction, industry, ships and other fields.

At present, the most common glass wool on the market is yellow, so it is also known as yellow cotton by the industry. In fact, glass wool in addition to yellow, there are other colors, white is one of them.

White glass wool is not made by adding bleach or pigment, but by adding an acrylic binder. This is because the traditional glass wool products in the production process using phenolic resin as a binder, and this resin more or less have some harmful substances, and the use of acrylic adhesives is no formaldehyde, phenol, urea and other harmful substances, so white glass wool is also known as formaldehyde-free glass wool.

Formaldehyde-free glass wool can be said to be an upgrade of ordinary glass wool, in addition to all the performance characteristics and application fields of yellow cotton, its glass fiber diameter is smaller, so the thermal conductivity is lower, and the thermal insulation performance is better. In addition, white glass wool can also be used in places with particularly high requirements for the environment, such as hospitals, chemical laboratories, biological laboratories, food processing plants, etc.

In addition to white and yellow glass wool, glass wool is also available in pink. Pink glass wool is mainly used in the field of acoustics for sound absorption and sound insulation to achieve noise reduction.

Glass wool has white, known as formaldehyde-free glass wool, in addition to white glass wool there are pink glass wool, used in the field of acoustics.
