An aerosol container comprising:
- a vial body containing an aerosol formulation of a suspension or solution of a medicament in a hydrogen-containing fluorocarbon liquid propellant, and
- a valve for dispensing a metered amount of the aerosol formulation per actuation thereof,
- wherein the valve comprises a valve body defining a metering chamber configured to contain a metered amount of the aerosol formulation for dispensing by the valve, a transfer passage through which the metered amount of the aerosol formulation is able to pass from the vial body into the metering chamber, and dispensing means which enables the metered amount of the aerosol formulation to be dispensed from the metering chamber;
- and
- wherein the metering chamber is made from a plastics material which is a mixture of a fluorinated polymer and a non-fluorinated polymer.
