The society of Flame-retardant Material Background This society was established in 1996 as a research group dealing with only flame retardant materials and technology in Japan. Our purpose is to improve flame retardant technology base by sharing and studying flame retardant technology and peripheral technologies around them. It is aimed to establish the world's No.1 fire protection rate for people's lives and property by spreading flame retardant technology. 1. Sharing technical information (product introduction, academic research,
regulation, environment) 2. Research on Flame Retardant Technology (Mechanism of Combustion
Phenomena, New Field) 3. Member intercommunication (holding symposium, issuing books) Number of members: approximately 500, Sponsored companies: About 250

Flame retardant is one method of protecting people's lives and properties from fire. Currently the number of fires in Japan is in the past 5 years, about 64,000 cases, approximately 2,000 people for the victims. Also, most of them are elderly people and infants, and the victims are biased toward the socially vulnerable. As one means of solving, by developing advanced flame retardant materials, the goal is to secure the time to escape from the fire and to protect the people's lives and wealth from fires.

Flame retardant standard
Flame retardancy standards are different for each product due to different use conditions and shapes, so there are flame retardancy tests as each product standard, and representative examples are shown below. As a flame-retardant standard trend, the fire accident is moving year by year towards a tough direction

Flame retardant technology is aimed at securing time to escape from the fire by developing advanced flame retardant materials and protecting public life and property from fire. The flame retardant has the following problems. Standard issue There is no definition of "flame retardant level“ in world wide , so there are many flame retardant standards for each application. Besides, it differs among the world countries. At present, the movements of global standardization are gradually beginning, but the claims of each country are also different. The situation is chaotic.
Summary The issue of flame retardancy
FRTECH 難燃材料研究会
Environmental issues A flame retardant having a large addition amount to the resin tends to be regulated as with the plasticizer. Waves of regulation that started with specific bromine flame retardants such as RoHs Directive and Environmental Label have also spread to phosphorus flame retardants. Technical problems Flame retardants are required to balance environmental performance and flame retardant effect. That is, both efficiency and effect are required. For example, alternatives for improving the environmental performance of a combination system with a brominated flame retardant / antimony oxide having the highest flame retardant effect have been sought. It is nearing the time to consider seriously the balance between environmental performance and flame retardant effect.
