What are the flame retardants for LCD screens?

The flame retardant of LCD is a material that can slow down or prevent the burning of substances under fire or high temperature conditions. Choosing a suitable flame retardant can improve the safety of equipment and can meet the requirements of safety standards. During the manufacturing process, the commonly used flame retardants are as follows:

1. Flame Retardant Brominated Compounds

Brominated compounds are currently one of the most widely used flame retardants for liquid crystal displays, including isopropyl bromide, hexabromobiphenyl and dodecabromodiphenyl ether, etc. These compounds are mainly added to the matrix to achieve for the purpose of flame retardancy, bromine compounds have the advantages of good flame retardancy and low cost, but they may cause environmental pollution and toxicity problems during use, so they have been banned in some countries.

2. Flame Retardant Phosphoric Acid Series Compounds

LCD liquid crystal screen phosphoric acid series compounds such as trichlorophosphoric acid and triphenoxyphosphoric acid, etc., are often used as flame retardants for liquid crystal display backplane materials. These compounds have thermal stability and oxidation stability, and can effectively exert flame retardant, and will not pollute the environment like brominated compounds, so it is widely used.

3. Flame Retardant Nitrogen Series Compounds

LCD liquid crystal screen nitrogen series compounds such as polyurethane, epoxy aminotriphenol and expanded polyurethane are also commonly used flame retardants for LCD backplane materials. These compounds have good flame retardancy and high temperature resistance, but they are relatively expensive in price. In addition, their application range still needs further research and development.

The selection of flame retardant materials for LCD liquid crystal screens mainly depends on the requirements of the application scenarios of liquid crystal displays. Various factors should be considered comprehensively when selecting, such as flame retardant performance, cost, environmental protection and production technology, so as to ensure safety. At the same time, maintain appropriate cost and market competitiveness.
