Feature

●Material: Sound-absorbing Material: Polyurethane; Size: 11.8 x 11.8 x 1.0 inches (30 x 30 x 2.5 cm); No glue (double-sided tape is required to attach to the wall)
●It is very easy to cut with a utility knife, etc. It can also be used with adhesive spray glue or paper bond, and can be pasted
●Flame retardant material is used, so it is highly safe and prevents fire from transferring even under high temperatures
●Sound-absorbing sponge is primarily used for soundproofing and soundproofing indoors and if you want to reduce outside noise, depending on the volume and nature of the sound source, it may not provide sufficient sound insulation effect
●The polyurethane sponge will be shipped compressed and put it in about 24-48 hours after opening, and the compression will recover naturally. If the restorative effect is not good, please soak it in water, wring it out, and it will recover immediately


Description

Product Specifications:
Material: Sound-absorbing material: Polyurethane.
Size: 11.8 x 11.8 x 1.0 inches (30 x 30 x 2.5 cm); No glue (double-sided tape is required to attach to the wall).

Sound absorbing principle:
The sound-absorbing sponge is filled with fine voids and semi-open structures, which absorb more sound waves that come in, demonstrate the attenuation effect of sound attenuation, reducing interference and reverberation of sound emitted indoors and preserves the sound purity. The higher the density of the sponge, the better the sound absorption and sound insulation.
Product Application:
Suitable for sound absorbing materials in car AV, home AV, piano, music room, etc.
Flame Retardant Description:
Flame retardant means you can remove the hidden danger of the flame and will automatically disappear in about 3 seconds from the open flame. If you cannot control the source of the fire, it will continue to burn and will not completely prevent burning. Please acknowledge
DIY:
It is very easy to cut with a utility knife, etc. It can also be used with adhesive spray glue or paper bond, and can be pasted.

Note:
The polyurethane sponge will be shipped compressed and put it in about 24-48 hours after opening, and the compression will recover naturally. If the restorative effect is not good, please soak it in water, wring it out, and it will recover immediately.
