Basalt Roving

Description and basalt roving range, also known as basalt or stone thread. We provide prices upon request

Basalt roving is a bundle of continuous unidirectional complex basalt fibers. Roving has high natural strength, resistance to aggressive environments, long service life and excellent electrical insulation properties. In terms of its technical characteristics, basalt roving surpasses S-glass and E-glass in many respects, and is not much inferior to carbon. Basalt roving is extremely heat-resistant: the temperature range for long-term use is from –260°C to +680°C. It can withstand temperatures up to 1000 °C for a short time.

Roving marking:

Technobasalt® Roving RB-16-T8/1250

where

RB — basalt roving;

16 — the diameter of the monofilament (μm);

Т8 — type of lubricant;

1250 — linear density of roving (tex).

Basalt roving is manufactured in the following size ranges:

by the diameter of the monofilament: 9/13/16 microns;
by its density: from 330 to 4 800 tex*.

* Tex is the density of the roving, expressed as the weight in grams of 1 kilometer of thread.

Different types of sizing (reagents) are used depending on the intended application of the roving.

Roving is delivered in bobbins with internal or external unwinding, with or without a spool.



Basalt roving is multifaceted

Basalt roving is widely used. People wind pipes and barrels from it, make wind generator blades, propellers for boats, use in spray application, in the manufacturing of refractories, pultruded products, basalt fabrics, plaster and nets, car bodies and interiors, boats and yachts, high-pressure cylinders, artificial rattan furniture, filters of treatment facilities, etc.



Basalt roving has unique properties

High mechanical strength, corrosion and chemical resistance to alkalis, acids, and other aggressive media.
High frost resistance, heat resistance, moisture resistance.
High sound absorption.
Ability to filter aggressive substances.
Low thermal conductivity.
Resistance to salt seawater.
Resistance to ultraviolet radiation.
Dielectricity and diamagnetic.
Environmental friendliness.



Basalt roving is the best substitute for fiberglass

Having higher strength and less brittleness, basalt roving easily replaces glass fiber, thus ensuring the reliability and durability of finished products.



Basalt roving is a great alternative to carbon fiber (carbon)

Basalt is slightly inferior to carbon in terms of modulus of elasticity, but it is more resistant to point impact loads, less brittle and, unlike carbon, is a dielectric. In addition, basalt, unlike carbon fiber, has a much higher fire resistance.
