Speaking of Foam Lost Foam , do you know what he does? He is a tool used in our environmental protection work and has made a great contribution to us. When he uses it, there are some things that need attention. Do you know? Our plastic bag wholesale manufacturer will explain his sound insulation methods for you today, let's take a look together. Foam Lost Foam sound insulation is mainly through two ways. One is to absorb the energy of sound waves to reduce reflection and transmission. Because this product has low electrical conductivity, it can easily generate its own electrification phenomenon during friction. It will have an impact, but for high-precision electronic products, especially large-scale integrated block structural elements of modern appliances, we should use anti-static EPS products. Second, eliminating resonance can reduce noise, anti-aging, and corrosion performance. Except for long-term exposure to high-energy radiation, the product has no obvious aging phenomenon and can withstand many anti-static properties such as chemicals.
