Materials based on basalt fiber have the following important properties: porosity, temperature resistance, chemical resistance
and water vapor permeability.
Porosity of materials made from basalt fiber can reach up to
75% of their volume. If the pores of the material are filled with
air, then it has low heat conductivity.
Due to all these properties Basalt Stone Fibers & materials
derived from them are increasingly being utilized as rebar in
building reinforcement, strengthening agents in concrete
mixtures, thermal insulation, industrial filters, and many more.
Basalt Stone Fibers
Basalt Stone Fibers are high quality strands of stone with
many practical applications. These fibers are environmentally friendly and are made from naturally occurring basalt rock.
These basalt rocks are melted at about 2,500 degrees Fahrenheit to form ultra-thin micro strands. Two hundred of these micro strands form one thread of basalt stone fiber.
The resulting product is a lightweight, durable, and very
strong material.
Basalt stone fibers boast an industry leading strength-to-weight ratio exceeding 3 times the strength of steel. Unlike metals, Basalt Stone Fibers do not succumb to corrosion and have a much higher chemical resistance against water, oils, salts, acids, solvents, and alkalis.
