WGMT Formaldehyde-free and Acrylic-free Glass Wool Tube

This formaldehyde-free and acrylic-free glass wool is made from natural minerals such as quartz sand, dolomite, borax and other inorganic materials, mixed according to specific process formula ratio requirements, and after high-temperature hot melting at 1360℃, it is made into a series of products such as glass wool felt and glass wool board using advanced centrifugal fiber-forming technology.

Product Introduction

Formaldehyde-free glass wool changes the harm to the human body caused by formaldehyde contained in traditional glass wool by improving the adhesive and not using designated restricted chemical substances in the production method.

Application

Formaldehyde-free and acrylic-free glass wool can be widely used in various sterile environments such as medical places, pharmaceutical workshops, and high-end commercial buildings for metal duct external insulation, duct internal insulation, ceiling and direct duct, equipment insulation, sound absorption and noise reduction, prevention of condensation and condensation, and energy saving.

Product Performance

Good thermal insulation performance

Good sound absorption performance

No formaldehyde

No odor

Reduce stinging sensation

Good fire resistance

The use of fine fibers increases the number of fibers, improves the insulation effect, and compared to 80K rock wool, 16~24KAclear can achieve equal or better insulation performance. It can reduce the weight of insulation materials by 70~80%, achieving significant lightweighting.

The fiber refinement technology improves the sound absorption performance and can improve the sound insulation performance.

No materials containing formaldehyde are used during the production process, achieving a comfortable indoor air environment.

By changing the adhesive, the peculiar odor of glass wool and rock wool is also eliminated.

Formaldehyde-free glass wool makes the feel of glass wool softer by improving adhesives and refining fibers, which greatly reduces the tingling sensation unique to traditional rock wool and glass wool, and also improves the on-site working environment.

Glass wool has passed the GB8624-2006 combustion performance A2 test, with a combustion grade of A2 and produces no toxic gas or smoke.
