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
