Combustible heat source with improved binding agent

摘要

A combustible heat source (4) for a smoking article (2) comprises carbon and a binding agent. The binding agent includes a combination of three binder components: an organic polymeric binder material, a carboxylate burn salt and a non-combustible inorganic binder material. The at least one non-combustible inorganic binder material comprises a sheet silicate material. Preferably, the combustible heat source further comprises an ignition aid.
