Inorganic formaldehyde free and environmentally friendly glass wool

Huali Formaldehyde Free Environmental glass wool is a product made by centrifuging molten glass and applying heat to fix resin. The fiber structure inside the glass wool is fluffy and interlaced, with a large number of small air pores. A fiber type insulation and sound-absorbing material with open holes, mainly composed of glass fiber and thermosetting resin. Due to the use of a special formula that does not contain formaldehyde, it can be made into glass wool felt and glass wool board, widely used in clean laboratories, HVAC, and various places with special requirements for indoor environmental quality.
