Dymel® is the DuPont registered trademark for a range of propellants which are suitable for many aerosol production
applications.
Vapor pressures of Dymel® A, Dymel® 152a, and Dymel® 134a are shown in Figure 1. 
When blended with hydrocarbon propellants or low-boiling solvents, higher or
lower pressures can be reached if required.
Because they are soluble in each other, with hydrocarbon propellants, and with a wide variety of common aerosol
solvents and products, Dymel® propellants can be blended to provide effective delivery of water-based or solvent based products. Dymel® A is exceptional in terms of its water solubility.
The basic physical properties of the Dymel® propellants, detailed in the table below, can be
summarized as follows:
Dymel® A is a medium-high pressure propellant with a high degree of solubility in water (weight percent at
autogenous pressure) and high solvency. It is miscible with most conventional solvents. Its LEL (lower explosive
limit) in air is higher than that of hydrocarbon propellants.
Dymel® 152a is similar to Dymel® A in vapor pressure, but has a low water solubility, is a moderately weak solvent,
and is flammable but, similar to Dymel® A, has a LEL
about twice that of hydrocarbons.
Dymel® 134a is the only non-flammable propellant in the Dymel® series.
