Butanone Podcast Chemistry World
Although polystyrene cement is marketed as a glue, it’s not. Rather than acting as a genuine adhesive – binding to the surface of the material – butanone is effectively a chemical welding agent. The plastic surfaces dissolve on contact, and then as the ‘glue’ evaporates away, they repolymerise into a new, bonded structure.
