[Summary]Flame retardants are compounding agents that can delay or prevent the combustion of polymeric materials. Adding flame retardants to rubber products is what we often see. Halogen flame retardants, phosphorus flame retardants, nitrogen flame retardants, phosphorus-halogen flame retardants, and phosphorus-nitrogen flame retardants are all flame retardants, but the flame retardant elements are different.

The most commonly used halogen flame retardant is oxidized paraffin wax, which is a compound of oxygen and bromine. Its flame retardant effect is related to the structure. During the pyrolysis process, it can decompose the elements that pass the combustion free radicals, and it can also dilute the combustible material. The combustible gas produced during the pyrolysis process is cut off the contact between the combustible gas and the air.

Phosphorus flame retardants mainly include ammonia polyphosphate and phosphate ester flame retardants. Phosphoric anhydride is produced in the combustion process, which promotes the dehydration and carbonization of combustibles and prevents the production of combustible gases. At the same time, it can also form a melt covering the surface of combustibles during pyrolysis, which plays a flame retardant role.

The role of nitrogen and combustibles in nitrogen-based flame retardants can promote cross-linking into carbon and reduce the decomposition temperature of combustibles.

Flame retardants can also be divided into inorganic salt flame retardants, organic flame retardants and organic inorganic mixed flame retardants.

Inorganic flame retardants are environmentally friendly flame retardants, will not produce harmful gases when burning, low smoke, non-toxic in line with national requirements, safety is relatively high, both flame retardant and can reduce the cost of materials, commonly used inorganic flame retardants are aluminum hydroxide, magnesium hydroxide and so on. The organic flame retardants are mainly halogen, phosphate, halogenated phosphate, etc., organic and inorganic hybrid flame retardants can replace some of the inorganic inhibitors.

Flame retardants are widely used in various fields because of their corresponding characteristics, and the flame retardant effect increases with the increase of flame retardants. When each inhibitor is used alone, there is a minimum dosage, so we should use it as required!
