PET Sound-absorbing Nonwoven Batting is made by processing 100% polyester fiber (PET), heat-pressed and formed in the shape of cocoon or honeycomb. Product Index are Noise reduction coefficient: 0.79 (GB47-83)；Sound absorption coefficient: 

NRC=0.81 (GB47-83)；Heat conduction coefficient:   0.035 (GB/T10295-88). Its processing method is simple, using art knives or scissors to cut into the desired shape. It is also convenient to use, and can be directly pasted on walls or ceilings without the need for protective layers, or can directly fill as a hidden filling sound-absorbing and thermal-insulating material.

    1、Product Features:

    （1）High sound absorption rate, Good sound insulation performance: PET Sound-absorbing Nonwoven Batting, with porous structure material, allows sound to form a backflow in its high-density fiber cavity, effectively achieving sound absorption and noise reduction functions;

     （2）Good thermal insulation performance;

    （3）Flame retardancy: Sound-absorbing Nonwoven Batting made of high-quality polyester fiber meets the B1 level combustion performance of building materials by experimental testing at the National Fire Equipment Quality Inspection Center;

    （4）Tight structure and Stable shape;

    （5）Lightweight, Safe and convenient construction;

    （6）Without formaldehyde, the product is harmless to the human body. After multiple experiments, it has been proven that it has no allergic reactions to human skin, no pollution to the environment, and no odor;

    （7）Waterproof: After water immersion, it has strong drainage, no decrease in sound absorption performance, and unchanged shape;

    （8）It can be reused, easy to destroy, and has no secondary pollution to the environment.

    2、Product Uses:

    The products, which are widely used in public places such as piano rooms, mechanical rooms, meeting rooms, gymnasiums, music halls, recording studios and highway sound-insulating walls, have completely replaced harmful sound-absorbing materials such as fiberglass, rock fiber and sponge.
