Foam Blowing

It was demonstrated that TDCE is very effective at reducing the vapor pressure and viscosity of some HFCs/polyol premixes by virtue of its improved solubility, as well as dramatically reducing the degree of frothing and number of pin-holes. Most recent works found that TDCE provided a valuable combination of processing and property improvements in HFC-245fa blown spray wall formulations and was one of the factors in achieving a class I ASTM E-84 rating. Many HFCs blended with Trans-1,2-Dichlorothyelene improve on foam fire performance of Urethane foam.

TDCE is also work with next generation of HFOs very well. Except the function above, blending with TDCE will lower the total cost in these applications.

Experiments has shown many HFCs/HFOs are good candidates to remove flash point of TDCE. This eliminates the concern about the flammability of TDCE.
