Alternative products for viscose fiber flame retardants mainly include the following:

1, phosphorus flame retardant: phosphorus flame retardant is a new type of flame retardant that has developed rapidly in recent years, and its advantages are non-toxic, smokeless, does not produce harmful gases, and the flame retardant effect is durable. Phosphorous flame retardants form a protective film on the surface of combustibles, making combustibles difficult to burn under the action of oxygen and heat, so as to achieve the purpose of flame retardation.

2, nitrogen flame retardant: nitrogen flame retardant is also a new type of flame retardant, its advantages are less use, obvious flame retardant effect, and will not produce harmful gases. Nitrogen flame retardants mainly inhibit the chemical reaction in the combustion process of combustibles, making it difficult to burn or decompose, so as to achieve the purpose of flame retardation.

3, silicon flame retardant: silicon flame retardant is a more common flame retardant, its advantages are good stability, not easy to decompose, and environmentally friendly. Silicon flame retardants mainly form a protective film on the surface of combustibles, so that combustibles are difficult to burn under the action of oxygen and heat, so as to achieve the purpose of flame retardation.

4, aluminum flame retardant: aluminum flame retardant is a more common flame retardant, its advantages are low cost, good effect, friendly to the environment. Aluminum flame retardants mainly inhibit the chemical reaction in the combustion process of combustibles, making it difficult to burn or decompose, so as to achieve the purpose of flame retardation.

In general, the alternative of flame retardants needs to take into account multiple factors such as environmental protection, safety, effectiveness and economy. When choosing an alternative, it is necessary to evaluate and select according to the actual situation to achieve the best flame retardant effect and environmental protection requirements.
