Fire extinguishing agent FK-5-1-12
( Chemical symbol : FK-5-1-12)
Chemical name: Perfluoro-2-methyl-3-ketone ; Perfluorinated - 2 - methyl - 3 – pentanone
FK-5-1-12 is in the character of high in efficiency on fire extinguishing, environmental profile, safety in use, is the ideal substitute of halon
and fluoroalkane halon.
Packing: steel drums, 250kg, 25kg
FK-5-1-12 is not IMO dangerous goods. Small quantity is available.
Perfluoro-2-methyl-3-ketone (Trade name:FK-5-1-12) belongs to perfluorinated ketone compounds,
and molecular formula is CF3CF2C(O)CF(CF3)2, structured is:
FK-5-1-12 is a clear, colourless, almost odourless, electrically non-conductive liquid fire
Physical properties of FK-5-1-12
Boiling point at 1013bar
Heat of vaporization at boiling point
Liquid Viscosity @25℃
Solubility of water in FK-5-1-12 @21℃
1. FK-5-1-12 has an excellent environmental profile and the low toxicity. FK-5-1-12 can be
long-term replacement halon fire extinguishing agent.
2. FK-5-1-12 is a highly efficient fire extinguishant
3. The extinguishing concentration of FK-5-1-12 is much lower than its NOAEL
4. FK-5-1-12 has noncorrosive harm , good insulation, no damage to sophisticated electronics
5. FK-5-1-12 is a liquid at room temperature, so the storage and transportation are convenient.
FK-5-1-12 has an excellent environmental profile. It doesn't have damage to the ozone layer,
and the ODP is 0，the GWP is 1, the ALT is o,o14 year. Although the ODP of fluoroalkane halon
substitute products is 0, its GWP is larger, which have a negative effect to the global warming
and climate change. FK 5112 can solve the two problems very well, that is the GWP and the
ODP very small, which is better than that of the halon fire extinguishing agent and other types
of fluoroalkane halon alternatives (HFC-227ea、HFC-236fa) at this point.
Compare to the Environmental spec of FK5112 and Halon and part of the product
Safe for people
The toxicity of FK-5-1-12 is very low, and the extinguishing concentration of FK-5-1-12 is
much lower than its NOAEL，so the FK-5-1-12 has a high safety. The fire extinguishing agent
has been registered by the USE.P.A.T.S.C.A.
The extinguishing concentration of FK-5-1-12 and Halon and part of fluoroalkane
Extinguishing Concentration (%)
Note: the NOAEL: invisible harm concentration
Can be seen from the table in the NOAEL FK-5-1-12 approximately twice the extinguishing
concentration, the safety margin is bigger; And slightly above its NOAEL of HFC - 227 ea
fire extinguishing concentration, the safety margin is small; Halon 1301 NOAEL and
extinguishing concentration is very close, no safety margin; HFC - 236 - fa NOAEL is
less than its extinguishing concentration, there is a danger to people. Therefore,
FK-5-1-12 extinguishing agent in extinguishing efficiency at the same time, more suitable
for the place of someone.
Non Damaging Fire Protection
FK-5-1-12 has no damage to electronics, electronic media or delicate mechanical equipment.
It’s an alternative to water sprinkler systems, dry chemicals and foam that protects your
Experiments show that FK-5-1-12 with other materials, such as rubber, metal, has good
compatibility, and little impact on a variety of materials used. Though FK-5-1-12 with metal
contact 10 days under 48 ℃,we did not find fade or damage phenomenon.
