Fire Protection,
Heat & Sound Insulation

 

- If you are interested in better fire protection and 150°C higher heat resistance than with E glass materials but less expensive than silica, you need fabrics from our basalt fiber

- If you need reliability, you will get it using materials made of our basalt fiber
Our advanced basalt fibers show 15-20% higher tensile strength and modulus, better chemical resistance, extended operating temperature range than regular E glass, getting close to high strength and corrosion resistant fibers but being less expensive.

Basalt fibers have better sound insulation properties than glass fibers. Hence, with interior based on basalt fiber you will feel yourself more comfortable.
The dielectric properties of basalt fibers are equal to ones of glass fibers. So, switch from glass to basalt does not change radar transparency of construction.
After exposition under 400C the basalt fibers lose only 20% of their initial strength, while strength of E glass under the same conditions drops substantially - more than 50%.

 

Kamenny Vek can provide various types of yarns and woven fabrics. We are open for collaboration in manufacturing of special design fabrics and braided sleeves. Our R&D team is ready to work and satisfy various customer requirements.
