Polyester fiber sound-absorbing panels have many advantages, including good sound absorption, good decoration, and easy processing. Every material is two-way. Now we will briefly talk about the disadvantages of polyester fiber sound-absorbing panels!
Weak water resistance
Polyester fiber sound-absorbing panels are not waterproof. Since polyester fiber sound-absorbing panels are made of polyester fiber by hot pressing, they are water-absorbent. They can absorb a small amount of water, but cannot absorb a large amount of water. They cannot be soaked in water.
Poor flame retardant performance
The flame retardancy of polyester fiber sound-absorbing panels can only reach the B1 level, which is self-extinguishing when exposed to fire. The flame-retardant properties of sound-absorbing panels soaked in flame retardants will evaporate and will have no flame-retardant effect after half a year. If a higher flame-retardant level is required, then Raw silk flame-retardant polyester fiber sound-absorbing panels
Not moisture proof
Wet walls will cause the polyester fiber sound-absorbing panels to become moldy. If they are light-colored polyester fiber sound-absorbing panels, there will be signs of water immersion.
Not soundproof
Polyester fiber sound-absorbing panels are not sound-insulating and have excellent sound-absorbing effects. However, many users think that polyester fiber sound-absorbing panels have very good sound-insulating effects. They are not. Don’t misunderstand.
