1, PU sponge

PU sponge is a kind of sound insulation material with very good performance. Usually, sponges are widely used in recording studios to achieve sound insulation effect. The sponge with sound insulation groove treatment on the surface has better sound insulation effect. This kind of sponge is often called wave cotton.

PU sponge has strong water absorption capacity and is easy to absorb dust. If it is used as a sound insulation material for windows, it is easy to absorb water in rainy days or when wiping with wet cloth, which will rust the iron frame on the windows. However, many people's windows are not exposed to rain now, so it is still very practical and you can consider it again when choosing.

2. Polyurethane foam

Polyurethane foam is the main component that makes up the styrofoam. Cured polyurethane foam material can play a better sound insulation, sound insulation performance, and anti-corrosion, waterproof, and better polyurethane material has flame retardant design, is a good choice of sound insulation materials.

3, calm sound insulation cotton

calm sound insulation cotton takes industrial rubber and plastic as the carrier, adds various specifications of sound insulation particles, nitrogen foam molding, gray black appearance. Its front surface is covered by miniature sound insulation holes and special-shaped sound insulation grooves, which efficiently filters noise of different frequencies and wavelengths, integrates sound insulation and attraction functions, meets the requirements of light weight and environmental protection of home decoration sound insulation materials, and has high cost performance.

4. Sound insulation damping felt

Sound insulation damping felt is refined from a variety of organic minerals according to a certain proportion by introducing foreign advanced technology. Sound insulation felt has good sound insulation performance in broadband and high damping performance, and is a new type of sound insulation material that controls noise attenuation in the transmission path.

high-density special materials are mixed to achieve a very good sound insulation and noise reduction effect, so that the sound insulation felt shows excellent performance in isolating air sound and impact sound, and the sound energy is lost in the sound insulation material. The isolation has incomparable effects to other materials, and it is an excellent multi-purpose sound insulation material.

With the white-hot market cabinet equipment, the situation of sound insulation cotton manufacturers is also very embarrassing, and the market of sound insulation cotton manufacturers is also green and yellow. Jinger environment has 10 years of professional production experience and product quality assurance, is also the preferred choice of customers.

Characteristics of flame retardant foam

Flame retardant foam is in the nature of the original EVA products to add a flame retardant solvent or powder into, so that EVA products play the role of flame retardant, chemical name is ethylene-vinyl acetate copolymer.

Wonderful use of sound insulation cotton

Sound insulation cotton is a special material, its main function is sound insulation. In modern society, sound insulation cotton is widely used in construction, automobiles, ships, aviation and other fields. The wonderful use of sound insulation cotton is multifaceted, let's take a closer look at it.

Advantages and uses of sound-absorbing cotton

Advantages and USES of sound-absorbing cotton: 1.100% environmentally friendly products, 100% recyclable; 2. Strong, easy to use and tasteless, waterproof, moisture-proof, good air permeability, easy to process, can be made into various shapes according to different needs.
