Insulfrax Blanket products manufactured by the Unifrax Corporation have been designed to provide passive fire protection, reports IFJ.
The Unifrax Corporation’s latest development is the  Insulfrax S Blanket designed to offer industrial users improved thermal and physical characteristics for passive heat protection.
Manufactured using enhanced techniques which combine new proprietary processing technology, the result has been a stronger, flexible non-woven blanket which offers higher temperature capability than the original Insulfrax Blanket that it replaces, with its classification temperature now raised to 1,200°C.
As with the original Insulfrax product, Insulfrax S Blanket retains its excellent thermal conductivity, thermal shock resistance and low heat storage, as well as ease of cutting and fabrication, says the manufacturer.
“Responding to customer comments, the significantly improved physical characteristics of Insulfrax S Blanket make it better suited for those applications which demand good strength, flexibility and low dust,” comments Unifrax’s Alasdair Stevenson.
“Additionally the new Insulfrax S Blanket exhibits a higher melting point and reduced shrinkage at high temperature demonstrating superior thermal performance.”
The latest Insulfrax Fibre, used to manufacture Insulfrax S Blanket, is based upon a low impurity calcium-magnesium-silicate (CMS) chemistry. In addition to higher temperature resistance, Insulfrax Fibre has high solubility in simulated body fluids and hence carries no hazard classification, meeting stringent European regulatory requirements (Directive 97/69/EC).
Insulfrax Thermal Insulation is also available in the following product forms: Insulfrax Bulk and Chopped Fibres, Insulfrax Board, Insulfrax Paper, Insulfrax Felt, Insulfrax Pumpable and Moldable Mastics, Insulfrax Rigiform, GC50 and Flexiform Shapes, and Insulfrax IG Tape. Specialised Blanket products such as Insulfrax WR (water repellent), SF (foil-faced) and SFR (reinforced foil-faced) are also available.
Insulfrax Blanket  products manufactured by the Unifrax Corporation are ideal materials for providing passive fire protection to structures based on lightweight materials and also traditional steel.
“Insulfrax  Blanket is a totally inorganic, flexible, high-temperature insulation blanket which is ideally suited to marine passive fire protection applications,” said a company spokesman. 
The material offers high tensile strength and superior thermal and acoustical properties and has received MED approval for steel and aluminium structures, U.S. Coast Guard approval for steel and aluminium structures and complies with SOLAS Safety Objectives and IMO FTP Code fire test requirements.
