EXPANDABLE COMPOSITION IN THE FORM OF A GRANULAR MATERIAL

摘要

The present invention relates to expandable compositions in the form of granular materials that are based on epoxy resins with a content of binders and curing agents for curing the epoxy resin. Corresponding compositions can be readily introduced into hollow bodies, for example, into sticks or roof supports and expanded to a foam by heating the composition and cured. This results in hollow bodies filled with foam that are distinguished by significantly improved mechanical properties compared to comparable hollow bodies without a foam filling. At the same time, the granular materials according to the invention can be very readily processed without a complex and expensive two-component injection-molding process being necessary.
