1. Fire Extinguishing Concentration:
TF112 has excellent fire performance, and its fire extinguishing concentration for class A is only 3.5%, its fire extinguishing concentration for class B is only 4.5% which is the closest to the halon, and it is far less than other fluoroalkane halon substitute.
It can save A, B, C fires, non-conductive, immediately gasification after the injection, no residue.

Extinguishing Concentration Comparison:
- TF112: 4-6%
- Halon 1301: 5%
- HFC-227ea: 7.5-8.7%
- CO2: 30-75%

2. Product Advantages:
1. TF112 has an excellent environmental profile and low toxicity. TF112 can be long-term replacement halon fire extinguishing agent.
2. TF112 is a highly efficient fire extinguishant.
3. The extinguishing concentration of TF112 is much lower than its NOAEL.
4. TF112 has noncorrosive harm, good insulation, no damage to sophisticated electronics.
5. TF112 is a liquid at room temperature, so the storage and transportation are convenient.

3. Environmental Performance:
TF112 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 0.014 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. TF112 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.

4. Effects on Equipment and Materials:
Experiments show that TF112 with other materials, such as rubber, metal, has good compatibility, and little impact on a variety of materials used. Though TF112 with metal contact 10 days under 48°C, we did not find fade or damage phenomenon.

5. Application Field:
TF112 fire extinguishing agent can be used in the whole area or local area fire extinguishing system and portable fire extinguisher, and it has a wide range of applications, so it suitable for fire extinguishing work but relatively closed places.
TF112 can be used as a protection gas during melting of magnesium alloy or other light metal alloy to replace SF6.
Applications: Data centers, Electronic control centers, Precision instruments, Archives, Libraries, Museums, Naval ships, Ocean-going vessels, Commercial aviation, Subway stations, Shopping malls, Assembly occupancies
