What is the sound insulation of the wall?
Soundproof material The product substrate is a high density EPDM or PVC polymer material. Due to the particularity of EPDM and PVC polymer structure, it is determined that the acoustic impedance of the material is particularly high. At the same time sound insulation material in the production process filled with high-density minerals, an increase of the noise density of the material, so that sound insulation material in the isolated air and impact sound show excellent performance.
EPDM or other polymer materials with the physical properties can not change the characteristics of high temperature and low temperature conditions should not be broken and soft, so that the product always maintain the same sound insulation performance, and can be different for the frequency of noise. Felt and other sound-absorbing materials, such as cotton felt, foam or rock wool composite use, the sound insulation performance will be more excellent.
Sound insulation material within the damping high, for the low-frequency noise isolation with the rest of the material unparalleled effect. Soundproof material unique flexibility, easy to suppress the generation of resonance. At the same time, the sound insulation material and other lightweight materials to avoid the effect of anastomosis.
Damping sound insulation felt, the material used in Europe's most advanced production technology, in the domestic production of a wall with a soundproof material. Is a green, economical and durable products, the service life of 50 years.
