Sound-absorbing cotton

The sound-absorbing cotton uses Korean technology to melt the heat to achieve a variety of density, making it an excellent product in sound-absorbing materials, decorative materials, sound insulation materials.
Detailed introduction

Product Overview:

Polyester fiber sound-absorbing cotton is a new product developed to replace glass fiber, rock wool, sponge and other harmful sound-absorbing materials. It is made of 100% polyester fiber and made of cocoon cotton after hot pressing. Use public heat treatment method to achieve density diversification, making it an excellent product among sound absorbing materials, decorative materials and sound insulation materials. Its environmental protection performance is its biggest advantage. The test data reaches the national E1 level. The evaluation is that it can directly contact the human body. It is the most efficient sound-absorbing and heat-insulating material that is closest to nature and harmless to the human body and the environment. Its fire resistance is B1, which is a flame-resistant product. Its sound absorption performance has been recognized by the majority of acoustic experts. Environmental sound-absorbing cotton is fully used in Europe and the United States. It is used to replace harmful sound-absorbing materials such as glass fiber and rock wool sponge in public places such as piano rooms, machine rooms, conference rooms, gyms, concert halls, recording rooms, highway soundproof walls, etc.

Performance characteristics:

(1) High sound absorption rate and good sound insulation performance. Polyester fiber sound absorption cotton is a porous material, which can make the sound form a backflow in its cavity through the special high-density tissue of the fiber, effectively achieving the sound absorption and sound insulation function.

(2) Good thermal insulation

(3) Flame retardancy: Polyester fiber sound-absorbing cotton is experimentally tested at the National Fire Equipment Quality Inspection Center, and has reached the B1 level of building material combustion performance.

(4) Tight structure and stable form.

(5) Light weight, safe and convenient construction.

(6) The product does not contain formaldehyde, which is harmless to the human body. It has been proven through many experiments that it has no allergies to human skin, no pollution to the environment, and no odor.

(7) Waterproof, strong drainage after water immersion, sound absorption performance does not decrease, and shape remains unchanged.

(8) Can be used twice, easy to destroy, and has no secondary pollution to the environment.

Product specifications: Production and processing according to requirements to meet user requirements.

Fourth, processing method: use a utility knife or scissors to cut into the required shape.

V. Widely used in: acoustics, craftsmanship, packaging, decoration, water cluster filters, building materials, home piano rooms, bedrooms, partition walls, top decoration and public places such as sports halls, concert halls, cinemas, auditoriums, etc.

Note: can be processed and produced according to customer needs
