LOW DENSITY FIRE BARRIER MATERIAL AND METHOD OF MAKING

摘要

This invention relates to a fire barrier material comprising at least about 25 weight % binder; at least about 10 weight % intumescent compound; and at least about 5 weight % organic fibers comprising an organic material having pendant hydroxyl groups, wherein the density of the fire barrier material ranges from greater than zero to about 0.35 grams/cm3 as well as a method of making the fire barrier material.
