Product category
Rubber soundproof material
Acoustic pad SI-2501
I. Product Features:
1. The sound energy loss is large, the acoustic energy barrier effect is obvious, and the barrier property is good (2mm thickness weighted sound insulation amount exceeds 27dB).
2. Both the burning and the level of smoke poisoning have reached the domestic advanced level, with an oxygen index of more than 32%.
3, high strength materials, good flexibility, can be arbitrary bending.
4, the material itself does not contain lead, cadmium, chloride ions, pH value in line with European standards, no pollution to the environment.
5, construction is convenient, dry construction.
6, the use of low cost, easy maintenance.
