What is flame retardant finishing ?

Flame retardant finishing is a process used to treat textiles and other materials to make them less flammable and slow the spread of fire. The finishing process involves applying a chemical treatment to the surface of the material, which helps to reduce its flammability and prevent ignition.

There are several different types of flame retardant chemicals that can be used, including halogenated flame retardants, intumescent flame retardants, and phosphorous-based flame retardants. The choice of flame retardant chemical depends on the type of material being treated and its intended use.

Flame retardant finishing is commonly used in a wide range of applications, including the manufacture of protective clothing, upholstery, curtains, and other textiles used in buildings and other structures. It is also used in the manufacture of electronic devices and other products that require flame-resistant properties. The use of flame retardant finishing can improve the safety of materials and reduce the risk of fire, but it can also raise concerns about the environmental impact of the chemicals used and their potential health effects.
