CHARACTERISTICS

Saffil mats are light, flexible mats needled with polypropylene threads made from high-purity polycrystalline wool. The polypropylene threads allow a higher strength and flexibility of the mat. The temperature resistance is up to 1600 ° C. Saffil mats can be used in a wide variety of applications. They are particularly suitable for applications where shot (melt beads) are not desired or where resistance to corrosion is important.

benefits

  • High temperature resistance (up to 1600 ° C)
  • Low thermal conductivity
  • no visible shot
  • Thermal shock resistance & durability
       to chemicals
  • High tensile strength and resilience
  • insoluble in water
  • suitable for facings and anchor modules

PRODUCT TYPE

Mats (blankets) made of high temperature wool are needled lightweight mats and provide an effective solution for a wide range of thermal insulation applications. They are characterized by excellent insulating properties, high resistance to chemicals, elasticity and dimensional stability. They are exclusively inorganic and therefore do not generate smoke or fumes when exposed to heat. They are available in a wide range of densities and thickness combinations, making them one of the most versatile product groups on the market.

MATERIAL

Polycrystalline wool (PCW Poly Crystalline Wool) consist of fibers with a very high alumina content (Al2O3 > 70% by weight %). They are produced from aqueous spinning solutions using the “sol-gel process”. During the subsequent heat treatment, the previously produced, water-soluble green fibers crystallize. Polycrystalline wools are generally used at operating temperatures> 1300 ° C or, in the case of critical chemical and physical application conditions, also at lower temperatures. The first production of polycrystalline wool can be traced back to the 1970s.
