Rock Wool Board insulation foil aluminum
1,Rock wool board
2,Low price,good quality
3,Excellent insulation materials
Rock wool is made of select fine basalt as the major material,
which is pulled into 4-7 non-continuous fibers after melted by
adopting advanced international four-roller centrifugal
cotton-making procedures and adding a certain of adhesives, dust
laying oil and water repellent into rock wool fibers. It can be
made into rock wool products series with different density
according to various uses through the technology of sedimentation,
solidify and cutting etc.
1) Excellent thermal insulation, mechanical, fireproof and sound
2) High acidity coefficient, good chemical stability and fiber
3) Low cost and high temperature resistance
1) Petrochemical industry -- heat insulation and sound absorption
of equipments for petroleum industry, power industry and chemical
2) Construction industry -- heat insulation and sound absorption of
partition, curtain wall, roofs and fences for construction.
3) Mining industry -- heat preservation and fireproof for
industrial kiln, oven, large-caliber storage tank and shipping.
