STAPLE BASALT FIBER

PRODUCT DATA SHEET

Basalt ‘chopped’ fiber is continuous filament cut to predetermined lengths to suit a particular application.

They are usually coated with a sizing/binder to make them compatible with other materials and elements with which it has to coexist the primary end product (concrete mix, for instance).

The ability of the basalt fiber to accept sizing is good. This is known as ‘wetout’.

High tensile strength
Alkali resistant
High thermal conductivity
No carcinogenic risk or other health hazards
Completely inert with no environmental risks
Resistant to acids and aggressive chemicals
High E modulus resulting in excellent specific tenacity, three times that of steel fiber
Good fatigue resistance
Electro-magnetic resistant

Typical uses for chopped fiber strands:

Basalt is the best reinforcement for concrete due to its tensile strength and natural resistance to deterioration from alkali
Reinforcement for composites, polyester/epoxy resins and plastics as used
in automotive body panels, boat hulls and pultruded products, etc.
Friction materials such as brake pads and linings
Manufacture of basalt mat/felt
High-temperature insulation applications
Passive fire protection materials
Filler for gypsum and sheetrock board requiring increased ‘burn-thru’ capability,
to meet building regulations
High-performance automotive muffler filler
