VV020-GLASS FIBER
Fiberglass for anticrack reinforcement
Benefits
- Excellent workability with gypsum and cement
- Control and prevention of breakage and cracking of the materials
- Simple and safe to apply, it increases the thixotropy of gypsum and cements
- High dispersion: 100 million filaments per kg of product
- Fiber length: 12 mm
- Virtually invisible on finished surfaces
Veltman VV020 non-woven glass fibers obtained by grinding the primary filament which are used as anti-crack reinforcement. Particularly suitable for both domestic and industrial processing, the VV020 glass fiber has a high degree of dispersion in gypsum, cements, water and casting masses.
- Fiber length: 12 mm
- Filament Diameter: 20 μm / 0.00078”
- Loss on Ignition (%): 0.60
- Moisture (%): 0.50 max.
- Electrical Conductivity: Very low
- Specific Gravity: 2.68 g/cm3
- Material: Alkali Resistant Glass
- Softening point: 860°C
- Chemical Resistance: Very high
- Modulus of elasticity: 72 GPa / 10 x 106 psi
