Temperature resistance
High temperature resistance up to 1600 ° C.
tensile strenght
High tensile strength and resilience.
Thermal conductivity
Low thermal conductivity.
PROPERTIES
Our polycrystalline mat 1600 ° C is a light, 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 resilience
- insoluble in water
- suitable for facings and anchor modules
PRODUCT TYPE
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.
Product variations
