What are the characteristics of "sponge products"? What are the uses of high-density elastic flame retardant sound-absorbing and

Foam, known as polyurethane foam, can be divided into rigid foam, flexible foam, high-density, low-density polyester foam and polyether foam. Most foams are made from polyisocyanates and polyols. The basic reaction is that the polyol and polyisocyanate react to form polyurethane.cellulose sponge factory At the same time, water and isocyanate reaction to generate carbon dioxide, gasification of the blowing agent produced by the gas to absorb the heat of the reaction began to escape the formation of bubbles, the formation of the "nucleating agent", and then into the "milk time" bubble expansion, and finally the formation of a stable foam system.

Sponge product characteristics: sponge foam can be divided into closed-cell foam and open-cell foam. Inside the closed-cell foam material, the bubble holes are separated from each other by the wall membrane, the wall membrane is an independent bubble structure, mainly small bubble holes or very fine microporous. Open-cell foam material in the bubble holes connected to each other and connected with the outer skin, for the non-independent bubble structure, mainly for the large bubble holes or coarse bubble holes.

Heat preservation and insulation characteristics: due to the foam material enterprise internal control contains China's large amount of research air or other gases, and is not suitable for circulation, especially closed-cell foam material, with a completely separate independent bubble hole, the material can significantly slow down the conduction of heat, with a very low cost of thermal conductivity, more combined with the development of the relevant materials itself soft, and good resilience can be done for our country's automobiles, ships, home appliances, Electronic information equipment, medical service equipment, fitness activity equipment, air conditioning system pipeline, etc. Ideal thermal insulation structure material .....

Cushioning high elasticity: sponge itself is famous for its high elasticity, after the sponge is processed into foam material, it still maintains high elasticity, which is very suitable for cushioning high elasticity....

High and low temperature resistance: excellent temperature resistance and weather resistance, can be used in -60 degrees Celsius and +160 degrees Celsius in a wide range of temperatures, with high and low temperature resistance, fire resistance, oil resistance, chemical corrosion resistance, can be widely used in anti-vibration, shock absorption, high and low temperature resistance, weathering, acid and alkali resistance, flame retardant industry....

Fireproof Sponge

Flame retardant: With strong flame retardant effect, these materials are made by foaming, due to its excellent flame retardant properties, it can be used in the field of higher requirements for fire protection.

Acoustic insulation: It is well known that sound waves propagate through the air in the form of vibrations. When the sound wave encounters the porous material, the vibration travels to the inside of the material and rubs against the complex bubbles inside, which is hindered and the energy is attenuated, so the sound wave is weakened, which is manifested in the absorption of sound wave by the material. Due to its unique features and the flexibility, flame retardancy and aging resistance that other materials do not have, open cell foam has become a new type of acoustic material.
