Cotton Durable Flame Retardant

Cotton Durable Flame Retardant

Among various textile materials, cotton has the lowest limiting oxygen index (LOI) of only 18, which belongs to flammable fiber and is very likely to cause fire, limiting its use. Therefore, it is particularly important to carry out flame retardant finishing of cotton fabrics.

Alfa Chemistry provides cotton durable flame retardant, which is a phosphate ester reactive flame retardant that contains dual flame retardant elements of phosphorus and nitrogen. Its active N-methylol groups enable it to cross-link with the fabric, providing permanent flame retardancy.
