Noise and Vibration Dampening (Part 2)

In our previous blogNoise and vibration dampening (Part 1), we learned the fundamentals of acoustic management solutions. In this blog, we'll be exploring some of the widely employed noise-blocking solutions by Boyd:

• Boyd's SOLIMIDE® Foams-SOLIMIDE® Foams are Boyd's specialty open-celled polyimide foams are designed to combine excellent lightweight, thermal, and acoustic properties with enhanced fire protection and safety characteristics. These foams can withstand continuous use temperatures up to 200-300°C and still maintain stability and pliancy when immersed in liquid nitrogen. SOLIMIDE® Foam exceeds FAR 25.856 fire resistance specifications, will not burn and emits very little smoke when exposed to flame, making SOLIMIDE® the ideal noise absorbing material for safety-critical applications in eMobility, defense, and aerospace. Industrial applications where reducing noise and vibration while maintaining high cleanliness like semiconductor manufacturing benefit from SOLIMIDE® Foams' low off-gassing and formaldehyde-free construction, that possess high hydrolytic stability and doesn't not support microbial growth.
• Roger's PORON® urethane foams -PORON®氨基烷泡沫是具有高维稳定性和出色粘弹性的开放式材料，在持续振动下良好。由于对压力，放松和压缩的高度抗性，尿烷泡沫不会在压力下塌陷，并且始终返回其原始尺寸的99％。确保在关键应用中的一致性和可靠性，在各种结构中都可以看到尿电烷泡沫，从额外的柔软，非常柔软，柔软，牢固到非常牢固。这些耐用的泡沫具有阻燃，耐化学性，并且可以维持从-40°C到90°C的广泛温度。这些泡沫配备了出色的间隙填充，密封和垫圈特性，可为中度和高冲击力提供良好的吸收。
  
• Roger's BISCO® silicones-Bisco®有机硅由细胞，实心或特种有机硅材料制成，具有与Poron®氨基甲烷泡沫相似的好处和功能。主要的区分因子仍然是Bisco®有机硅的高火耐药性和承受高温的能力。细胞硅酮具有不同的厚度，可高度抗压和高拉伸强度。由固体橡胶样材料制成的固体硅酮可在10-40岸A的一系列均可使用A中使用。特种有机硅，将蜂窝和固体硅酮组合在一起，可在40-70岸A中看到。。
  
• 3M的振动阻尼和光滑的表面磁带- With a soft aluminum backing, the vibration damping tapes from 3M mitigate resonant noise, vibration, and fatigue. Used for attaching irregular and uneven surfaces, the tapes can hold up to 50 pounds per square inch of strength. They are pressure-sensitive tapes with high viscoelasticity that reduces stress and dissipate noise across the surface. Similar to vibration damping tapes, very high bond (VHB) tapes from 3M also offer dampening properties due to their high viscoelasticity. Slick surface tapes from 3M utilize Ultra-High Molecular Weight Polyethylene (UHMW-PE) and Polytetrafluorethylene (PTFE) formulations to mitigate friction between the two contact surfaces.
