Engineered Rock Wool.
Built for Fire, Heat & Sound.
Borui delivers A1 non-combustible rock wool from one of China's largest dedicated mineral-wool groups — engineered for facades, industrial process piping, sandwich panels and marine duty.
A trusted Chinese rock wool partner for the world.
Ningbo Borui Trading is the international arm of Anhui Xuanming New Materials, a vertically integrated group operating three rock-wool plants across Anhui, Zhejiang and Shandong with a combined annual capacity of 110,000 tons.
We are co-authors of three Chinese national rock wool standards, a vice-chair of the China Insulation Association, and among the first enterprises certified under the Three-Star Green Building Materials programme.
