Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance.
Rock wool takes natural basalt as the main raw material, after high temperature melting, artificial inorganic fibers are made by high speed centrifugal equipment, at the same time, add special binder and dustproof oil, then through heat curing, made into a variety of specifications rock wool insulation products with different requirements. Rock wool products are widely used for construction, petroleum, electric power, metallurgy, textile, national defense, transportation and other industries, is the ideal material for thermal insulation and sound insulation of pipeline storage tank, boiler, flue, heat exchangers, fan, transport and other industrial equipment. Rock wool board can resist high temperature of 650 degrees. Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance. the internal side of centrifugal glass wool exists crisscross fibers and many tiny air voids, is typical porous sound-absorbing material, has good sound absorption characteristics. Glass wool can resist high temperature of 450 degrees.
Glass wool: Main raw material is glass, A level fireproof grade, thermal conductivity coefficient 0.037, thermal shrinkage temperature 270 degrees, application: obvious cold insulation effect. Rock wool: Main raw material is glass, A level fireproof grade, thermal conductivity coefficient 0.040, thermal shrinkage temperature 730 degrees, application: It'd used in construction, ship building, petroleum chemical and other high-end engineering. hope it can help you.

Rock wool is artificial light silicate, not the continuous flocculent fiber material, soft texture, good chemical stability, acid and alkali resistant. Not brittle or pulverization, good elasticity, it can be heat insulation, sound insulation in projects.
