In office buildings, shopping malls, hotels, and other office spaces, there are high requirements for sound absorption, fire resistance, and decorative effects. Mineral wool boards are widely used in ceiling systems due to their excellent sound absorption properties and Class A fire resistance.

Schools, hospitals, and public institutions have high requirements for environmental protection and acoustic environment. Mineral wool boards can effectively improve the indoor acoustic environment and meet the safety standards for public buildings.

Cellulose ethers (HPMC/MC) are key additives in dry powder mortar systems and are widely used to improve material properties.

Cellulose ethers can significantly improve workability and product stability in tile adhesives, putty powders, gypsum products, and wall materials.
