As a filler and reinforcing phase for road, waterproofing and sealing asphalt to improve softening point, penetration, rutting resistance and durability.
Validation route
Confirm the matrix, target properties and process window, then select surface treatment, run a dosage gradient and retest performance. Published data does not replace customer-specific validation.
Role in the material system
Whiskers can act as a microscale reinforcement or work with mineral fillers, glass fibre and functional additives. Performance depends on polarity, dispersion, interface, shear, temperature and moisture rather than dosage alone.
Evaluation route
- Provide the baseline formulation, process window and target properties.
- Select crystal form, surface treatment and at least two dosage levels.
- Compare performance, processing stability and unit cost in a laboratory trial.
- Run a pilot on production equipment to confirm feeding, dispersion, appearance and continuity.
Key observations
- Balance of mechanical properties and durability
- Flow, viscosity, dispersion and surface quality
- Thermal stability, dimensional change and cycle time
- Unit cost and realistic replacement potential
From pilot to production
Suggested values define the first test range. After formulation verification, sample specification, quality-control items and stable supply can be confirmed.
Parameters and test conditions
Page data supports early decisions. Final grades, dosage and process parameters must be validated in the customer system.
