Insulfrax® Fibre is a synthetic vitreous fibre based on a calcium, magnesium and silicate composition. A high fibre index (low percentage of unfiberised particles) provides the excellent thermal performance associated with traditional fibrous insulating materials. Insulfrax fibre is available in both chopped (3011) and unchopped (3010) grades. This fibre is the feedstock used to manufacture the Insulfrax product line, and it is ideally suited for conversion to boards, coatings and vacuum cast shapes. Insulfrax Fiber was developed for the temperature range extending from cryogenic levels through to 1100 °C. The wide operating temperature range combined with superior wetting resistance to molten aluminium alloys makes this product ideal for conversion to vacuum-cast shapes for metal transfer in the aluminium industry.
Insulfrax low bio-persistent products are designed to have enhanced in-vitro solubility characteristics, which enable Insulfrax products to meet European regulatory requirements (Directive 97/69/EC) for synthetic vitreous fibres.
