1. The glass fiber needled felt has good heat insulation: According to the physical principle, the thermal conductivity of the gas is small, and there are many air holes inside the excellent heat insulation material. The glass fiber acupuncture cotton has innumerable tiny gas, and the fiber presents irregular arrangement, it is an excellent thermal insulation material, thermal conductivity coefficient is 0.2-0.040kcal/mhr. c between;
2, will not burn: The main component of glass fiber is silicide (more than 50%), non-flammable, no deformation, no embrittlement, high temperature up to 7000C;
3, sound absorption rate is good: When the sound waves invade the glass fiber cotton, the period of energy due to the friction with the fiber and the size of the cavitation, and a lot of inhalation. In general, the sound absorption rate is as high as 90% or more, which is a good way to prevent noise interference.
4, high insulation: glass fiber can withstand high temperature, good mechanical properties, and high chemical stability, is the best insulation material.
