Polycrystalline mat 1600°C




Mat (Blanket)
SKU: N/A Category:

temperature resistance

High temperature resistance up to 1600 °C.


Tensile strength

High tensile strength and springback.


Thermal conductivity

Low thermal conductivity.


Our Polycrystalline Mat 1600°C is a lightweight flexible mat 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. Our Polycrystalline Mat 1600°C can be used in a variety of applications. It is particularly suitable for applications where shot (melt beads) are not desired or where resistance to corrosion is important.


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


Mats (Blankets) made of high temperature wool are needled lightweight mats made of ceramic (ASW/RCF) or biosoluble (AES) high temperature wool (HTW) and provide an effective solution for a wide range of thermal insulation applications. They feature 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.


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