Polymeric crosslinked network density: British American TobaccoRecent Research Landscape

The mechanical and diffusive properties of a gel are engineered by controlling the density and nature of crosslinks within a polymer matrix. This enables precise tuning of viscoelasticity and solute release rates for targeted delivery or structural applications.

What technical problems is British American Tobacco addressing in Polymeric crosslinked network density?

Uncontrolled tobacco additive release

(8)evidences

The keywords focus on the delivery and assembly of additives within filter tows. The technical problem is the inconsistent or premature release of volatile constituents during consumption.
