Product details

Rock Wool Products are manufactured with basalt as main ingredient,made into inorganic fiber in high speed centrifugal machine after melting, A certain amount of cementing agent, rustproof oil, silicon oil is added into the raw materials which is made into rockwool board, rockwool pipe shell, etc. (according to different customer requirement)
Moisture-proof aluminum foil, black (white) glass fiber cloth, sandwich glass fiber felt and moisture-proof facings can be stuck on surface of rock wool board.


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 ans 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, especially for large and key projects. The products are also sold to more than 10 countries/regions abroad.

1. Introduction

Rock wool board

Rock wool is an artificial inorganic fiber made from melted basalt slag wool at high temperature.

It has the characteristics of light weight, small thermal conductivity, good sound absorption performance, non-combustible and good chemical stability.


2. Advantages

Primary advantages of rock wool panel

1)Fire protection: The panel material is non-combustible materials, which can fully meet the requirements of fire protection regulations. The combustion performance depends on how much of the flammable binder is present. Rockwool itself is an inorganic mineral fiber so that not flammable. The using life of the board can reach more than 35 years.

2)Sound insulation performance: Rockwool products have excellent sound insulation and sound absorption. The sound absorption mechanism is the product’s porous structure. When the sound waves pass, friction is generated due to the flow resistance, so that the sound energy is partially absorbs and impedes the transmission of sound waves.

3)Insulation: Rockwool has low thermal conductivity and good thermal insulation. The good thermal insulation performance is the basic characteristics of rock wool and its products. Under normal temperature conditions (about 250C), the thermal conductivity of rock wool is usually between 0.03 and 0.047W/(m·K).


3.Main functions

What is the purpose of the rock wool board?

Marine rock wool board for thermal insulation and fireproofing of ships.

Waterproof rock wool board for vehicles, mobile equipment, cold storage projects, air conditioning ducts.

The rock wool board for construction has excellent fireproof, thermal insulation and sound absorbing properties.


4. Where can rock wool board be used?

Rockwool composite panels are widely used in the ceilings and partitions of steel structure workshops, roofs of simple movable houses, walls, and air clean rooms.

The rock wool panel is suitable for temperature control process, energy conservation and personal protection of equipment and pipelines such as boilers, steam pipes, heat exchangers, reactors, ovens, furnaces, etc., and has good sound absorption, noise reduction and fire prevention.


5. Applications

In modern society, new material rock wool board have been widely used in construction, metallurgy, chemical, electric power, petroleum, agriculture, machinery, light industry, textile, military, transportation, warehousing and other industries. Various buildings, industrial furnaces, boilers, heat exchangers, distillation towers, storage tanks, cold storage flue, pipes, valves, fans, air conditioners, vehicles and ships, as well as the development of modern defense, aerospace, and atomic energy technologies are all this new type of multi-functional material for thermal insulation, sound absorption and noise reduction.


a)Building energy efficiency

b)Industrial insulation
