MECHANICAL STABILITY OF INTUMESCENT CHARS

Intumescent fire-retardant systems have been studied in detail from al l points of view. However, all works passed around questions of mechan ical stability of foamed chars produced during burning. In the present work, mechanical properties of intumescent chars has been discussed. Technique and method of such investigations have been supposed. It was supposed that mechanical stability of foamed chars correlates with hi gh molecular fraction in char residue. (C) 1998 John Wiley & Sons, Inc .
