Yidebao Technology Development Co., Ltd. is a technology-based enterprise specializing in the production and research and development of new NVH sound-absorbing materials and thermal insulation materials. Its main products include: melt-blown two-component sound-absorbing cotton, sound-insulating and heat-insulating pads, special insulation cotton for shoes and clothing, and Two-component sound-absorbing cotton complete set of equipment. The company’s melt-blown two-component series products are widely used in automobile interior sound absorption, heat insulation, down jacket warmth, oil pollution treatment, military supplies (military cotton jackets, quilts, etc.), shoes, warm gloves, composite fabrics, medical health and other industries.
Sound-absorbing cotton is a kind of man-made inorganic fiber made from natural minerals such as quartz sand, limestone, and dolomite as the main raw materials. It has sound-absorbing and heat-insulating effects.
Sound-absorbing cotton is divided into glass fiber sound-absorbing cotton and polyester fiber sound-absorbing cotton. The differences between the two materials are introduced below.
First of all, know that the sound-absorbing effects of these two materials are similar, but glass fiber is not environmentally friendly and inconvenient to construct, while polyester fiber has poor flame retardancy and is even more flammable than wood. Polyester fiber is less expensive than fiberglass.
