Insulfrax Paper
Insulfrax® Paper is an evolutionary product for forming uniform, lightweight, flexible materials. The Insulfrax fibre used in Insulfrax paper is based on a calcium, magnesium and silicate (CMS) fibre chemistry. This CMS fibre chemistry has been successfully applied to solve a variety of application problems from 800° to 1300° C. In addition to high temperature resistance, Insulfrax Fibre meets European regulatory requirements (Directive 97/69 / EC). The chemical composition provides excellent wetting resistance to molten aluminium alloys. Tests on corrosive aluminium alloys at elevated temperatures have proven that Insulfrax is superior to traditional alumina/silica refractory ceramic fibres. Insulfrax Paper will generate small amounts of smoke and trace element outgassing during initial exposure to temperatures above 450°F (232°C).
