Insulfrax® 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.
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 427°C (800°F) up to 1100°C (2012°F). In addition to high temperature resistance, Insulfrax Fiber meets European regulatory requirements (Directive 97/69/EC).
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. Insulfrax Paper will generate small amounts of smoke and trace element outgassing during initial exposure to temperatures above 232°C (450°F). Insulfrax Paper offers many unique problem-solving advantages, which include: high-temperature stability up to 1100°C (2012°F), meets European regulatory requirements, superior wetting resistance to molten aluminum, low thermal conductivity, flexibility, and easy to wrap, shape or cut.
