Rock wool are made of highquality natural basalt ore as the main raw material, through high-temperature melting, high-speed centrifugal filament shaking, advanced three-dimensional production technology, adding a small amount of binder, and heat curing and setting.
Because of its natural rock material and porous structure, the product has excellent thermal insulation, sound insulation and fire resistance. In the case of fire, no smoke is produced, and the material is completely non combustible. It can be used as the heat preservation, sound insulation and fireproof insulation of bulkhead, deck and equipment, pipeline, etc. It can also be used as the core material of the vessel sanitary unit, floating floor and composite wall. Its excellent compression and tensile properties, a very low water absorption, can meet the needs of various insulation ship.
It can be based on customer demand, coated aluminum foil cloth or glass cloth and other decorative materials in the product surface.
Thermal insulation: With low shot content, long and thin porous fiber structure, low thermal conductivity,excellent thermal insulation effect.
Fireproofing: High quality raw materials, high temperature process, ensure the fireproof performance of products; will not produce fuel dripping, no toxic fumes produced.
Noise Reduction: A large number of internal rock wool fiber forming porous structure is communicated,high porosity, so that the rock wool products with high sound absorption characteristics.
Hydrophobic & Breathable: The hydrophobic technology of the product ensures that the rock wool is not damp absorbed and used for a long time on the ship, and the porous interconnection structure makes the product have good air permeability and moisture removal performance.
Good Strength: Three dimensional production technologies is adopted to ensure the high pressure and high tensile strength of the product.
Healthy & Environment: No asbestos, non carcinogenic, IARCY (International Agency for research on cancer) has been removed the rock wool from the list of "can cause cancer"; rock wool is chemically inert, neutral or alkaline water extract, no damage or corrosion and contact materials.
Applications: Products can be arbitrarily cut, convenient construction.

The selection of products, according to the needs of the products by thermal conductivity to calculate the corresponding thickness and proper density (45-150kg/m3 , 30-150mm), It is convenient when single-layer constructed, if double-layer insulation is selected, the structure will be more reliable and the sound insulation effect will be more perfect.
