A process for the production of a moulding composed of foamed polytetrafluoroethylene by means of an extruder, includes introducing a foaming agent, which brings about foaming, into the polytetrafluoro-ethylene, where the extruder used includes a commercially available extruder, to which a thermoplastically processable, fusible polytetrafluoroethylene is fed, the polytetrafluoroethylene is fed to the extruder together with a foaming agent which has chemical action and which has a decomposition temperature of at least 320&#xb0; C., and after its discharge from the extruder, the moulding is drawn off in the direction of production without any further measures relating to the foaming procedure.

A foaming composition comprising a melt processible fluoropolymer, and a chemical foaming agent, where the chemical foaming agent is ammonium polyphosphate.

High processing temperature foaming polymer composition

An insulation material based on polymeric plastic is specified, to which glass particles that consist of types of glass with different softening points are added for stabilization in case of fire. To provide protection in a very broad temperature range, at least three types of glass with different softening points are used as the glass particles, namely, a first type of glass with a softening point below about 470&#xb0; C., a second type of glass with a softening point above about 470&#xb0; C. and below about 620&#xb0; C., and a third type of glass with a softening point above about 760&#xb0; C.
