fireproof acoustic insulation foam

acoustic insulation foam: 1. OEM manufacture. 2. UL94HF-1 certified. 3. Fire-proofing. 4. RoHS complaint.

UL94 certified  acoustic insulation foam block

  

We can procuce according to customer request, special specifications can be customized and processing.

Sound-absorbing principle:there are amounts of micro connected pores in the materials,and through the pores waves go deep into the materials and convert sound energy into heat energy.

Product specification:Standard size: 2000×1000×30mm(thickness depends on your demand)

density: 14-60kg/m3

Applications:electrical and mechanical equipment, aerospace, metallurgy, machinery, medical equipment, environmental protection, automotive, Marine, architectural decoration, household appliance;etc.
