Q:Are fireproof glass wool and centrifugal glass wool the same?

Although both of which are glass wool, there are main three types of products involved. Centifugal glass wool includes hydrophobic glass wool and ordinary glass wool. Centrifugal glass wool is produced from centrifugal injection. The centrifugal glass wool you said is only a general name, and it also belongs to centrifugal glass wool material.

Q:whether the sound insulation is asbestos good or the glass wool good?

Because the main function is the fireproofing), sound absorption cotton belongs to asbestos, but match up with the installation (glass fiber cloth, and we in real life (in fact, we need the material with good sound insulation

Q:Does rock wool board refer to the glass wool ?

The difference between rock wool and glass wool 1. same raw material, 2, same products performance, the unit weight of glass wool is lower than rock wool, less slag ball, low heat conductivity coefficient, good fiber tenacity, and the using temperature of rock wool is about 600 degrees centigrades, glass wool is about 260 degrees centigrades, 3, products application: glass wool is used for the thermal insulation parts below 200 degrees centigrades,such as construction or low temperature pipe thermal insulation, rock wool is used in thermal insulation parts under 450 degrees centigrades, such as high temperature heat pipe or electric power equipment thermal insulation.

Q:These two kinds of glass wool are used as insulation materials, but one keeps 0.3 in specific gravity while the other keeps 0.5 in specific gravity. Which one should be chosen?

Generally, materials with high density have better insulation effect, consequently leading a relatively higher price. You can make a layer of polyurethane on the outside. Specific gravity is another way of saying density. Materials' thermal insulation effect is related to density. So if you want to get better thermal insulation effect, you can make a layer of polyurethane on the outside. It is noted that common polyurethane has a maximum temperature of 100 degrees, while high-temperature polyurethane requires 120 degrees.

Q:Is glass wool felt the mineral wool felt?
