Rockwool Rockwool sandwich panel Features: 1, fire performance 2, good insulation 3, heat absorption effect is remarkable. Rock wool sandwich panel leverages the unique properties of the core material in fire protection, thermal insulation, acoustic insulation, and so has a significant effect Rock wool is widely used in steel plants, simple activities room of the roof, walls, air clean room ceiling and partition. Rock wool sandwich panel, can generally be customized according to customer requests rockwool sandwich panel is a series of the most superior fire resistance of sandwich panels in different rock wool products, bulk density and thermal conductivity with different temperature change, which is mainly wool products is due to a large porosity of the material that the heat conduction, convection, and radiation heat transfer in three ways as volume and temperature changes caused by the different proportions of possession. Maximum temperature: rockwool maximum use temperature refers to its long-term use of the maximum allowable temperature. Rock wool fiber softening point 900-1000C, at 600C under long-term use will not undergo any change. Incombustible: either construction or other industries insulation field, incombustible material is essential. Incombustible concept refers to the given test conditions, the test furnace at 650C, the sample does not have any sense of burning. Long-term use Stability: rockwool products have chemical stability, timely long-term use in wet conditions will not occur deliquescence. Since joining the hydrophobic agent, rock wool products is almost non-absorbent, according JISA9512-1979 method to test its hydrophobic rate is over 99%
