In our article about the book “Introduction to flame retardancy” we highlighted the co-operation between Professor Masaru Kitano and BSEF in producing an English version of his book the book “Introduction to flame retardancy – Protect your life and property from fire”
This time we want to go deeper into flame retardancy science as the solution to minimize the human and economic damage caused by fires.
Flame retardants are a key component in increasing survival chances during a fire event as they allow longer escape times as well as longer response time for fire responders. They can prevent fires from starting, limit the spread of fire and minimize fire damage.
Some flame retardants work effectively on their own; others act as “synergists” to increase the fire protective benefits of other flame retardants.
Flame retardants are added to or incorporated into different materials or they are applied as a treatment to materials such as textiles and plastics.
They are the hidden protection against the potentially devastating impact of fire in so many products that we take for granted.
Flame retardants are used in four major areas to comply with fire safety requirements
As with all chemicals, flame retardants are regulated and their uses in products and materials are in accordance with chemical safety assessments.
World-wide there is substantial legislation in force regulating chemicals, for instance the EU’s REACH Regulation and the US Toxic Substances Control Act. These comprehensive laws ensure that chemicals, including flame retardants, are regulated in a way that protects human health and the environment.
Bromine is commonly used in flame retardants due to its high atomic mass and its general versatility across a wide range of applications and polymers.
There are more than 70 different types of brominated flame retardants with different properties (reactive, polymeric, halogenated…). Depending on the composition, nature and application of the materials or products that need to be rendered fire-safe, the correct type of flame retardants can be used.
Brominated Flame retardants contribute to the fire safety of electrical and electronic equipment and installations where printed circuit boards are used, such as consumer electronics (TVs, vacuum cleaners, washing machines), office and communication equipment (copiers, computers, printers, fax machines, radios, etc), automotive, aviation and all entertainment equipment.
At the end of a product or materials life, it is important to ensure as far as possible that the materials are reused or recycled. Printed circuit boards are for example recycled for the metals they contain.
Products or materials containing BFR’s are fully compatible with today’s integrated waste management optionsincluding mechanical recycling, chemical recycling, thermal processing/depolymerization/gasification all of which enable the recovery of valuable materials or energy.
