Whether The Flame Retardant Is Environmentally Friendly Or Not, Only To See It Contains Br?

Jun 01, 2018

It is clearly not true . A small number of halogenated flame retardants have environmental risks, but a flame retardant does not represent the whole flame retardant family. The brominated flame retardant family consists of more than 70 different chemicals, which have different characteristics. Each chemical substance has its own uniqueness and cannot be simply classified as a family based on an element in the chemical substance, and it is considered that the family has a common attribute.

The role of flame retardants is to prevent fires, delay the arrival of flashover and give people more chances to escape. The fire itself is toxic. The main causes of the fire deaths are toxic gases such as carbon monoxide, hydrogen cyanide and polycyclic aromatic hydrocarbons. Whether or not you use flame retardants, the use of brominated flame retardants will produce these toxic gases. Therefore, brominated flame retardant not only does not aggravate the toxicity of fire, but also can not be used for environmental protection from the angle of preventing the occurrence of fire and reducing the production of toxic gases.

At the same time, the TSCA, the European regulation, the registration, evaluation, authorization and limitation of chemicals (REACH), and a large number of other laws and regulations around the world are strictly regulated by chemicals including flame retardants. After strict evaluation, most brominated flame retardants can be used safely in consumer products. It is worth mentioning that BSEF's research on some brominated flame retardants, such as C15H12Br4O2, is more demanding for environmental protection and human health. For example, when used in printed circuit boards, C15H12Br4O2is a reactive flame retardant, which can eventually produce brominated epoxy resin. Such a circuit board has very low exposure to public chemicals and is highly safe.

It should be clarified that not all brominated flame retardants are persistent organic pollutants (POPs). Only one of the brominated flame retardants that is still in production and sales is POPs, that is C12H18Br6 (HBCD). The Stockholm convention of the United Nations Environment Programme (UNEP) was officially listed as POPs in 2013.

We provide a high quality environment-friendly flame retardant-YX3008 to replace HBCD production, with good flame retardant effect, environmental protection and reliability.
