AI Technical Summary

Technical Problem

In existing aerosol-generating systems, traditional aerosol-forming substrates tend to melt and form a shell during heating, leading to reduced equipment efficiency. At the same time, their insufficient mechanical strength makes it difficult to maintain their integrity during transportation and manufacturing.

Method used

An aerosol-forming substrate containing low-viscosity hydroxypropyl methylcellulose and one or more cellulose reinforcing agents is used. By adjusting the ratio of hydroxypropyl methylcellulose and cellulose reinforcing agents, the mechanical strength is improved and the shell formation is reduced.

Benefits of technology

This improves the mechanical strength of the aerosol-forming substrate, reduces shell formation, and enhances the operability of the manufacturing process and the efficiency of equipment use.

Abstract

An aerosol-forming substrate (1020) for use in an aerosol-generating system (2000). The aerosol-forming substrate (1020) comprises: one or more aerosol formers; hydroxypropylmethyl cellulose; and one or more cellulose based strengthening agents. The aerosol-forming substrate (1020) has an aerosol former content of greater than 30 percent by weight. The one or more cellulose based strengthening agents comprises cellulose powder. The aerosol-forming substrate (1020) has a cellulose powder content of between about 0.5 percent by weight and about 50 percent by weight.
