What are the flame retardant properties and types of "high efficiency density flame retardant" sponges?

This method of production of high-efficiency, high-density, flame-retardant sponge, mixed pore size, different thicknesses of the skeleton, large porosity, under pressure in different deformation state will produce different supportive reaction force.cellulose sponge factory Therefore, sofas, cushions, mattresses made of high rebound sponge can provide better comfort, i.e., a more desirable comfort factor, is a high-grade car seats. Its technology uses cold molding technology to form high regeneration curing polyurethane sponge plastic sofa seats and office seats, is an ideal material.

Fire retardant sponge performance aspects have through the following points:

The flame retardant sponge carbonizes the combustible material to achieve the flame retardant effect. This flame retardant effect mainly works in the solid phase, this flame retardant material is mainly phosphorus-based flame retardants (including organic and inorganic phosphorus).

Flame-retardant sponges form a non-volatile diaphragm under combustion conditions to isolate the air and achieve the purpose of flame retardancy. This flame retardant effect mainly works in the liquid phase. This type of flame retardant materials mainly include borates, halides, antimony oxide and phosphorus materials, or these materials reflect each other to produce substances.

The decomposition products of flame retardant sponges cut off the chain reaction of hydroxyl radicals and achieve the purpose of flame retardancy. This flame retardant effect works mainly in the gas phase. These materials are mainly used in the gas phase. These flame retardant materials are mainly halides and antimony oxide.

Dispersion of the heat of combustion and dilution of combustible substances. These flame retardant materials are mainly zinc borate, aluminum hydroxide, magnesium hydroxide and other substances, mainly because of the decomposition of a large number of heat-absorbing and non-combustible substances generated to dilute the combustible gases to achieve the purpose of flame retardant. Flame retardant system should generally be selected as far as possible non-toxic, economic, synergistic flame retardant materials. Commonly used flame retardant systems are: halogen - antimony oxide and phosphorus - nitrogen. However, the most commonly used is the hybrid flame retardant system, which can ensure the comprehensive flame retardant efficiency. According to the standard, the flame retardant performance of the product is generally tested by alcohol burner combustion test or simulated alley propane combustion test.
