Abstract
A fire barrier material comprising a combination of materials capable of melting progressively as the temperature rises under fire conditions, namely a relatively high melting devitrifying frit, one or more substances to reduce melt and flow temperature of the frit and, optionally, an intumescent substance and/or a pH buffer. The material is particularly suitable for use in thermoplastic materials.
