Rockwool is an inorganic material made from natural rock like basalt or dolomite as raw material. It is a Class A non-combustible insulation building material that can fully meet the national and industrial standards. It has the fireproof, heat and cold insulation properties. The market demand growth for the product as the exterior wall insulation material in China is relatively large.

In 2020, China rockwool production output was about 3.2 million tons. In 2021, the production output was about 3.38 million tons. It will be more than 3.8 million tons in 2023. There are more than 100 relatively larger rockwool enterprises in China. They have annual capacity of more than 20,000 tons per production line. Now the new single-line design capacity is about 30,000 tons per year. In the new production equipments, the electric furnace melting process of the production line has gradually increased.

In the early stage, the rockwool market had good benefits and all over the country increased the development and the investment of the production. In recent years, our state has repeatedly required to accelerate the use of electric furnaces to replace the use of cupola furnace in rockwool industry. Measures also have been taken to limit the use of cupola furnace production. It requires the enterprises to reduce the environmental pollution. It will continue to require the enterprises to improve production and pollution treatment equipments.

Many enterprises respond to the call of the state. They have transformed the existence equipment, upgraded production capacity and reduced environment pollution. In order to continue to develop rockwool industry in China, the structural adjustment will be the main development trend of the future rockwool industry.

With the support of national policies for the environmental protection industry, more and more people recognize the importance of environment protection. The proportion of new environmental protection building materials in China will be further expanded. The future development prospect of China rockwool market is good.
