Basalt

PROPERTIES OF BASALT

Basalt products possess unique characteristics:
 

  • low moisture intake
    10 times lower than glass fiber
     
  • great durability
    to aggressive media as well as to very high temperautres (maintains integrity up to 980°C)
     
  • good adhesion
    to epoxy binding agents
     
  • non flammable
    Basalt is non flammable
     
  • stable in volatile conditions
    stable dielectric and mechanical properties during continual operation in volatile conditions
     
  • resistant
    to chemicals, alkalines, acids, solvents, radiation, UV light and biological contamination
     
  • superior mechanical strength
     
  • superior chemical stability
