temperature resistance
High temperature resistance up to 1600 °C.
Tensile strength
High tensile strength and springback.
Thermal conductivity
Low thermal conductivity.
PROPERTIES
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.
Advantages
- 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
PRODUCT TYPE
MATERIAL
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.
