Features and advantages of products
1: High quality and extra fine, low slag-ball content and low coefficient of heat conductivity;
2: Wide range of bulk density (40kg-200kg/m3 ), wide range of specifications with all data being within/better than national standards;
3: Wide range of applications for construction, petroleum, electric power metallurgy, textile, national defence, transportation and other industries. Ideal material for heat insulation and sound insulation of industrial facilities such as tank, boiler, flue, heat exchanger, blower, vehicles and ships etc;
4: Owing to its large-scale production and advanced technology the products are salable in home market, espacially for large and key projects. The products are also sold to more than 10 countries/regions abroad.
Elastic MID-strength rock wool board: Used for heat preservation, fireproofing and sound absorption for the building wall/roof, such as curtain wall, inner wall partition and elevator hoistway, etc.
High-strength rock wool board: Used for various high/low temperature conditions, with good weight bearing ability and compression-resistance, specially suitable for heat preservation and heat insulation for large ships, tanks, ovens, . Pipelines and other industrial facilities.
Compress- resistant rock wool board: Used for roof heat preservation of airport lounge and large work shop as it could bear huge loads.
