Vertrel™ X-Si is a proprietary blend of Vertrel™ XF hydrofluorocarbon (2,3-dihydrodecafluoropentane) and hexamethyldisiloxane.
HFC-134a has very low acute toxicity by the inhalation route with a four-hour ALC in the rat of 567,000 ppm.
Freon™ 134a (HFC-134a; 1,1,1,2-tetrafluoroethane) is a nonflammable vapor at room temperature and atmospheric pressure.
Corrosion Inhibitors for Water-Based HP 152a Aerosol Formulations by J. A. Creazzo Wilmington, DE
For the full range of HP 152a/I compositions, this bulletin presents the saturated vapor pressures and liquid densities from 70°F to 130°F (21.1°C to 54.4°C) and flammability data for the vapor mixtures in air.
HP 152a (also known as HFC-152a or 1,1-difluoroethane) is a relatively inert chemical that is used in several commercial applications.
Physical Properties of HP 152a and n-Butane Mixtures HP 152a
Hydrofluorocarbon 152a (HFC-152a) is an aerosol propellant containing no chlorine atoms, and, as such, falls completely outside concerns about stratospheric ozone destruction by chlorofluorocarbons or other chlorinated hydrocarbons.
