Introduction
\n<\/strong>Insulfrax\u00ae Paper is an evolutionary product which is manufactured by forming Insulfrax Fiber in a nonwoven matrix. These fibers are randomly oriented during manufacturing and then held in place with a latex binder system. A specialized paper-making process is utilized to form uniform lightweight, flexible materials, including Insulfrax Paper.<\/p>\n

Insulfrax Fiber, utilized in Insulfrax Paper, is based upon a calcium, magnesium, silicate (CMS) chemistry. This CMS fiber chemistry has been successfully used to solve a variety of application problems from 800\u00b0F (427\u00b0C) up to 2012\u00b0F (1100\u00b0C). In addition to high temperature resistance, Insulfrax Fiber meets European regulatory requirements (Directive 97\/69\/EC).<\/p>\n

The calcium, magnesium, silicate chemistry of Insulfrax Fiber provides superior wetting resistance to molten aluminum alloys. Testing with corrosive aluminum alloys at elevated temperatures has proven that Insulfrax is superior to traditional alumina\/silica refractory ceramic fibers.<\/p>\n

Insulfrax Paper will generate small amounts of smoke and trace element outgassing during initial exposure to temperatures above 450\u00b0F (232\u00b0C).<\/p>\n

Health and Safety Information
\n<\/strong>Insulfrax Fiber from Unifrax, according to Directive 97\/69\/EC, possesses a fiber chemistry within the regulatory definition of a \u201cman-made vitreous (silicate) fiber with random orientation with alkaline oxide and alkaline earth oxide content greater than 18% by weight.\u201d Insulfrax Fibers have been tested pursuant to EU protocol ECB\/TM\/26, Revision 7, Nota Q, Directive 97\/69\/EC, with results that are below regulatory thresholds. As a result, Insulfrax Fibers do not require additional labeling or further testing.<\/p>\n

Refer to the product Material Safety Data Sheet (MSDS) for recommended work practices and other product safety information.\u00a0<\/strong><\/p>\n
