Basalt direct roving
Product Profile
Basalt direct roving
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
Product Application
In view of its excellent performance, basalt fiber roving can use in various fields:
Spray application
Pultrusion bar
Geogrid production
Basalt fabric
Pultrusion profiles
Car parts
High pressure vessel (winding)
