abrasive filaments HTF3 

Aramid filaments enriched about abrasive additions. From the point of view of the thermal endurance, stiffness and incorporating of different granularity of synthetic diamonds, silicone carbide (SiC), CBN or AL2O3 it goes about revolutionary application concept. The uniformly grain distribution from  rough #36 up to the finest #15000 makes possible the wide range of polishing, from high-performance to specular gloss.  


Advantages of the abrasive aramid filaments HTF3

  • multiple higher lifetime (according to the application field more than denary) in comparison with e.g. diamond brushing belts
  • substantially lower operating costs
  • self-cleaning effect of the tools (HiT-Brushes)
  • when being used it doesn´t get to getting round of the tools, it means uniform and even wear and tear of the brush surface
  • the outline treatment with the help of an exact formed tool
  • thickness and grain variability of the brush mounting
  • self-sharpening effect due to uniformly spread out diamond particles or silicone carbide
  • thermal endurance from -35°C up to 270°C (short-termly up to 300°C)
  • good filament features even when exposed to long-term high temperatures (by 250°C about 60% values like by room temperature)
  • excellent form stability ( < 1 % contraction from the room temperature to 250°C)
  • outstanding abradability and stiffness even by high temperatures
  • excellent chemical resistance against chemical substances
  • incombustibility UL94 V0
