Basalt direct roving1

Basalt assembled roving

Basalt direct roving is a continuous single-end strand produced pass through the bushing.
Basalt assembled roving consist of several single-end strand assembled together by special assembled machine.
Basalt direct roving can directly used in some industrial application, like textiles fabric, geogrid, woven thermal insulation tape/rope or pultrusion field. But some industrial application asks higher tex and external unwinding, that’s need basalt assembled roving.
Comparing to E-glass fiber and S-glass fiber, or even carbon fiber, basalt fiber has more natural performance advantages:

Thermophysical Properties

Using temperature / ℃ -260 – 700
Sintering temperature / ℃ 1050
Thermal conductivity / W/m.k 0.03 – 0.038
Strength retention after heat treatment
20℃ 100
200℃ 95
400℃ 82

Chemical Properties – Weightlessness

3-hour boiling in 2N HC1 2.20%
3-hour boiling in 2N NaOH 6.00%
3-hour boiling in H2O 0.20%

Moreover, basalt fiber roving has excellent mechanical and chemical performance as following technical:
■ High frost temperature resistance, high temperature resistance
■ Excellent thermal insulation
■ Corrosion and chemical resistance to alkali and resistance to salty sea water
■ Sound adsorption
■ Electric insulation
■ High tension strength and stiffness
■ Environmental friendly to soil, air and human
