Brief introduction of nano sponge

        Nano sponges are also called melamine foam sponges, melamine sponges or magic sponges, etc. Nano sponge is a new type of nano material successfully developed in the 1990s. In addition to excellent sound absorption and heat insulation, compared with similar products such as glass wool and polyurethane foam, its advantages are high flame retardancy, hygiene and safety. The nanosponge has no residual free formaldehyde, has stable chemical properties, and can meet food-grade hygiene requirements (the raw materials can be used to make tableware). And without adding any flame retardant, the flame retardant performance can reach the B1 level specified by DIN 4102 in Germany and the UL94-V0 level in the United States. It is a general foam plastic, such as polyolefin, polystyrene, polyurethane, etc. incomparable. The surface of the nanosponge burns slightly when exposed to an open flame, and forms coking, which extinguishes itself from the fire. When the surface layer is slightly burnt, nitrogen and carbon dioxide are released, which has fire-extinguishing properties, does not produce toxic smoke, and does not drip, thus greatly reducing the incidence of fire accidents.

At present, nano sponges are widely used in Europe and the United States. The main areas involve high-tech fields such as aviation, aerospace, military, and electronics to vehicles, trains, ships and other vehicles, from terminals, theaters, educational venues, recording studios, and cities. Expressway and high-noise working environment to ordinary household decoration, household appliances, daily cleaning products and other civil fields. It is a new type of material with great development prospects in the 21st century.

Features

• High open porosity, connected by filaments → outstanding sound absorption → three-dimensional grid structure system → good heat preservation effect.

• Its own flame retardancy → no need to add flame retardant to reach the B1 standard, no drips, no toxic smoke.

•High temperature stability→long-term working temperature 180-200℃.

•Flexible fiber yarn→outstanding cleaning effect.

• Chemical stability → resistance to strong alkalis and weak acids.

• Sound absorption, heat insulation, easy cleaning, etc., with strong flame retardancy and good cleaning effect.

Nano sponge performance

Nano sponge is a kind of low bulk density, high density structure, high open rate, flexible high temperature resistant nano superfine fiber foam plastic, with flame retardancy, sound absorption and heat insulation. It is widely used in acoustic engineering, architectural decoration industry, industry, transportation, aerospace, electromechanical, electrical appliances, electronic products, clothing fabrics, etc., which require sound quality improvement, noise control, heat insulation, etc.

Seven characteristics

Sound absorption

        The fully open three-dimensional grid structure system of melamine foam (the open cell rate of melamine foam with a density of 6kg/m3 is as high as 97%), so that the sound wave can easily and effectively enter the deep layer of the foam and transform into a grid Vibration can be consumed and absorbed, and effectively eliminate reflected waves.

Thermal insulation

The open cell rate of melamine foam is as high as 99%. Its three-dimensional grid structure effectively blocks the convective heat transfer of the air. Combined with its unique thermal stability, it becomes an irreplaceable lightweight thermal insulation mate

High flame resistance

Melamine foam plastic can reach GB/T8624-2006 B grade, DIN5510 S4 grade, B56853, UL94 V-0 grade without adding any flame retardant medium. After contacting the open flame, a dense coke layer is formed on the surface of the combustion body to block the combustion. There is no droplet, no toxic smoke, no combustion, and self-extinguishing away from the fire. , Smoke density <15. The book "Fire Safety and Flame Retardant Technology in Public Places" edited by the Ministry of Public Security is a flame retardant material in public places.

Thermal stability

Nano sponge is a thermosetting plastic, with a high degree of three-dimensional network cross-linking structure system, with high thermal stability and aging resistance. Nano sponge can work under the working condition of -180℃--+200℃ for a long time.

Good post-processing

The foam of Xiamen Share nano sponge can be conveniently processed into sheets and special-shaped materials by machining means, as well as sound-absorbing products whose surfaces are processed into cones and tapered shapes to meet the requirements of sound absorption.

Acoustic ceilings and coils with embossed patterns can be made by hot pressing, and the surface strength is improved. Easy to dye and manufacture into brightly colored hanging sound-absorbing materials.

Light weight

Nano sponge is one of the lightest foam plastics in the world, 4-12 kg/cubic.

safety

Nano sponge does not contain microfibers, no glass fiber powder or fly, no halogen or heavy metal flame retardants, its stable chemical structure and cross-linking system make it have unique chemical stability, which can meet the requirements of interior decoration, daily necessities, and Green safety standards in areas such as noise reduction in vehicles.
