What is a flame retardant?
Flame retardant is a chemical for improving the flammable properties of combustible such as fibers andplastics and making it less flammable. By properly processing the flame retardant, even if it comes in contact asmall fire source, it cannot be easily ignited. Even after igniting, it cannot be easily burned out by
self-extinguishing property.

Combustion

Those which have an effect of cutting off any of the combustion cycles are effective as flame retardants. Our“FRAN” series also this principle, breaking the combustion cycle by cutting off the element of “oxygen” andstopping burn.

Regulation on Antimony trioxide
In EU, antimony trioxide is regulated as second priority under Article 6 of the RoHS Directive. It is likely to be
regulated in other countries.

2Characteristics of FRAN CM series

1Strong CharThe FRAN CM series is characterized by “strong char” and it is different from other flame retardants. By“charring” only around the flame, it can prevent burning and maintain the shape of before burning.

Non-Formalin, Non-Halogen, Non-Antimony

The FRAN CM series consists of flame retardant containing phosphorus and nitrogen compounds, and isa product of non-formalin, non- halogen, non-antimony.
It doesn’t contain ingredients that cause serious damage to the human body. It can be used with security.
Because it is prepared with water dispersion type, it is suitable for work improvement and measuresagainst health damage due to dust.

3Low Smoke

The FRAN CM series has less smoke than antimony trioxide and can significantly reduce health damage
caused by fumes during fire.

4Flame Retardant Test of FRAN CM series
Based on UL-94 V＜Test method＞① Attach 125 mm x 13 mm sample vertically to theclamp.
Sample② Adjust the flame to 20 mm and flame contact for 10
seconds twice.
③ Observe the burning behavior at that time.
④ Perform the same operation as in ② and ③ 5times to make comprehensive judgment.
