Characteristics of inorganic flame retardants

High temperature can reach 1700 ℃, coating completely transparent, without any smell in room temperature and high temperature, inorganic flame retardant coating film after besmear to brush ring not the original color of object, inorganic flame retardant coating on the material of inorganic substrate, forming interpenetrating network structure and surface, good adhesion, heat insulation, anti-oxidation, anti-corrosion, flame retardant, fire protection, prolong the service life of the matrix, the energy conservation and environmental protection.An inorganic compound added to a polymer formulation that is flame retardant, coeffective flame retardant, or smokeless.

Generally including aluminum hydroxide, magnesium hydroxide, red phosphorus, ammonium polyphosphate, zinc borate, antimony oxide and molybdenum compounds.

Antimony oxide, zinc borate and other flame retardant effect is not significant when used alone, and halogen, phosphate ester and other organic flame retardant can significantly improve the flame retardant effect, so also known as flame retardant co-effect or flame retardant additives.

Inorganic flame retardants generally have low flame retardancy efficiency, large amount of addition, but small harmfulness and good smoke suppression effect.

The metal hydrates of inorganic flame retardants are mainly aluminum hydroxide and magnesium hydroxide.It has three functions: filler, flame retardant and smoke inhibitor.
