PROCESS FOR THE PREPARATION OF INORGANIC FOAMING AGENT MASTERBATCH
摘要
An inorganic foaming agent is economically and readily produced in the form of a masterbatch by melt-extruding one of the major components of the inorganic foaming agent with a carrier resin to prepare an intermediate masterbatch and blending the intermediate masterbatch with a composition containing the remaining component(s) or all of the components constituting the inorganic foaming agent.
