Good noise performance characteristics of foam board. EPS soundproofing products mainly through two ways, one is to absorb acoustic energy, reduce reflection and transmission; the second is to eliminate resonance and reduce noise. Good noise performance. EPS soundproofing products mainly through two ways, one is to absorb acoustic energy polystyrene sandwich board sales, reduce reflection and transmission; the second is to eliminate resonance and reduce noise. Has the ability to absorb shock loads. When subjected to impact loads EPS packaging products, foam and compressed gas through stagnation, so external energy is consumed, fugitive, bubbles smaller negative acceleration, gradual termination shock loads, so it has good shock effect.
