Patent attributes
Substrates for use with an aerosol delivery device to vaporize and deliver an aerosol to a user include a base material, an aerosol former and an aerosol agent. In a method for forming the substrates, a mixture of substrate materials is extruded and then spheronized to produce pellet substrates that are generally spherical, substantially spherical or rounded, or in the form of relatively short rods having rounded ends. In another method for forming the substrates, a base material is coated with a first coating and optionally the base material having the first coating thereon is subsequently coated with a second coating so as to produce pellet substrates having a relatively smooth, dry exterior surface. In this manner, the substrates are formable relative to one another and can be easily and readily loaded into and removed from the aerosol delivery device.
