Basalt Chopped Fibers

Basalt Chopped Fibers in general can be applied where E-Glass, sometimes S-Glass or Carbon Fibers can be used, as well.

.... more about the chopping process itself

As Basalt is more expensive than E-Glass, but cheaper than Carbon Fibers or S-Glass Fibers, it typically finds implementations, more suitable to its particular properties and fills an important gab when it comes to cost-performance ratios.

You can find a comparison to E-Glass, S-Glass or other materials by clicking here: Basic comparison to other fibers.

Knowing how Basalt compares to other fibers allow to precisely engineer an optimal solution, which could also be in form of a hybrid (combining Basalt with other Fibers made from Glass, Carbon, Kevlar, etc.)


An Example of an Engineered FRP. 

In Fiber Reinforcement Products (FRP) the engineer chooses the fiber, based on the desired outcome. E.g. if lighter weight requirements at identical strength to currently used fibers are required or if higher strengths are necessary while staying within the weight specifications.

There are other examples relevant to durability, corrosion resistances, break strength, chemical resistances, thermal applications, etc.

Our Team will be more than glad to assist or consult with design applications.



  • Leisure Industry (boats, surfboards, skateboards, etc)
  • Construction – reinforcements (asphalt, concrete)
  • Refractory – reinforcements (cermaic, microporous, other)
  • Processed into a Chopped Strand Mat
  • Processed into a Felt, Needled or acryclic bound like papers
  • Processed into a Phenolic Board
  • Thermal Insulation as filler material

Length: From 3mm (1/8 inch) up to 90mm (3.54 inch) are typical.

Filament diameter: From 13 micron up to 16 micron are standards

Chopped fibers can vary in looks when they are cut. Some distribute much more evenly others are staying together more like a strand; the choice depends on the application.
