To help our customers meet the drive towards non-chlorofluorocarbon delivery systems, global formulations, higher levels of product performance and the rationalisation of supplier bases Harp International Limited offers a "basket" of propellants.

• HARP^® Isobutane, HARP^® propane/butane (AP) blends: flammable, zero ozone depletion potential (ODP) hydrocarbon products. High chemical stability and purity. Blends available in several vapour pressure grades to satisfy specific applications.

• HARP^® DME (dimethyl ether): flammable, zero ODP medium-high pressure propellant. DME applcation technology is based on its compatibility with alcohols and water.

• HARP^® 134a and HARP^® 152a: zero ODP, medium-high pressure hydrofluorocarbon propellants. HARP^® 134a is non-flammable under all conditions. Both propellants are stable when used alone or with conventional aerosol solvents.

• HARP^® pentanes - volatile hydrocarbon liquids and vapour pressure modifiers.

• The optimum propellant may be a custom blend ot two or more HARP^® products. Please contact us for more information.
