1.Fire extinguishing concentrati&nbsp;

&nbsp;

TF112&nbsp;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.

2.Product advantage:

1. TF112&nbsp;has an excellent environmental profile and the low toxicity. TF112&nbsp;can be long-term replacement halon fire extinguishing agent.

2. TF112&nbsp;is a highly efficient fire extinguishant

3. The extinguishing concentration of TF112&nbsp;is much lower than its NOAEL

4. TF112&nbsp;has noncorrosive harm , good insulation, no damage tosophisticated electronics

5. TF112&nbsp;is a liquid at room temperature, so the storage and &nbsp;transportation are convenient.

&nbsp;

3.Environmental Performance of &nbsp;

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 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. TF112 can solve the two
problems very well, that is the GWP &nbsp;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.&nbsp;Effects on equipment and Mater&nbsp;

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 ℃, we did not find fade or damage phenomenon.

&nbsp;

5. Application field&nbsp;

&nbsp;

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. TF112 can be widely used in the
following areas:
