Formaldehyde-free and environmentally friendlyglass woolJust in the traditionalCentrifugal glass wool On this basis, some adjustments were made to the raw material formula and molding process of glass wool to make the raw cotton suitable for combining, curing and molding with the new binder. Since traditional glass wool products use phenolic resin as the main binder, harmful substances such as free formaldehyde, phenol, and urea will inevitably exist in the glass wool. Although its formaldehyde content complies with current domestic standards, the production of completely formaldehyde-free products Glass wool products have always been the direction of efforts of major glass wool manufacturers at home and abroad.

The adhesive used in formaldehyde-free environmentally friendly glass wool is completely different from traditional glass wool. It is an acrylic adhesive. It completely abandons toxic and harmful substances such as phenol, formaldehyde, and urea, and is therefore a revolution in traditional glass wool.Since we not only solved the binder problem, but also solved the curing problem and production cost control problem during the production process, Liangji has successfully produced high-density products.Formaldehyde-free glass wool(The maximum density can be 100 kg/m³)， Become one of the few manufacturers in the world that can produce both low-density and high-density formaldehyde-free environmentally friendly glass wool products. Therefore, this is the real reason why many international companies are seeking to cooperate with Liangji in technology, production, underwriting and even underwriting.
