1 Sound-absorbing Materials 2 Certification:ISO9001:2000 3 Material:polypropylene(PP) 4 Technic:meltblown PP Melt blown Nonwoven for Sound-absorbing  Introduction  Fiber fineness of material is 0.5-1.0μm.The random distribution of fiber provides more opportunities for thermal bonding fibers,so that melt-blown gas filter material has a greater surface area and higher porosity(≥75%). PP as the raw material,its fiber diameter can be reached 0.5-10micrometers.After unique processing, the microfiber has better sound absorption and heat insulation performance. Specification  1 High density2 Fne sound-absorbing and soundproof3 white, smooth and soft4 Eco friendly, anti-moisture5 Anti-aging, anti-aging  Technical Parameter
