Fire retardant and fire prevention technology development

Application of flame retardant

Flame retardants are mainly used in transportation, electrical and electronic equipment, furniture and building materials.Adding a flame retardant won't make the material completely fire-resistant, but it can still reduce the number of fires and buy valuable time for people caught in flames.In a space on fire, "flash-ignition" -- a simultaneous fire of various flammable substances within one to two seconds -- may occur due to the accumulation of flammable gases and heat.The emergence of flame retardant can effectively avoid this situation.A plastic-covered CRT TV, for example, would have less than two minutes to escape from a fire if it had not been treated with flame retardants. With the help of flame retardants, the escape time could have risen to more than 30 minutes.

The role of flame retardants in fire safety has been proven.The European Commission estimates that the use of flame retardants has reduced fire deaths in Europe by 20 percent over the past 10 years.According to the Greenstreet Berman study conducted by the British government in 2009, after the Furniture and Indoor Furnishings Fire Safety Code was enacted, there were 54 fire deaths, 780 non-fatal burns and 1,065 fire accidents on average between 2002 and 2007. Furnishings also need flame retardants for fire protection.

The experiment demonstrates

In 1987, the US National Bureau of Standards (NBS) used small and large tests to compare the fire risk of the following five typical plastic products with and without flame retardant types: 1.Polystyrene television housing;2. polyphenoxy computer housing;Polyurethane foam soft chair; 3.4. Cables with polyethylene insulation layer and rubber sheath;5. Unsaturated polyester FRP circuit board.

The test results were as follows:

1. The time available for evacuation of population and rescue of property after fire occurs is 15 times of that of non-flame retardant samples;
2. The mass loss rate of the material during combustion is less than 1/2 of the flame retardant sample;
3. The heat release rate of the material during combustion is only 1/4 that of the non-flame retardant sample;
4. The volume with toxic gas generated by material combustion (converted into CO), the flame retardant sample is only 1/3 of the non-flame retardant sample;
5. Flame retardant sample and non-flame retardant sample both combustion generated smoke amount is almost the same.Tests have also shown that the flame retardant materials do not produce extremely toxic or unusual combustion products.

Through the above experiments, we can draw a conclusion: through the reasonable fire safety design and the use of flame retardant products, can completely prevent the occurrence of noise.It is of great significance to promote the development of fire safety design.
