CONSTRUCTION-GRADE WOLLASTONITE FOR COMPOSITE SYSTEMS
TECHNICAL FILLER FOR STRENGTH, CRACK RESISTANCE & FIRE PERFORMANCE
Used in fiber-reinforced boards, adhesives, mortars, and engineered composites — wollastonite enhances performance across a wide range of building products.
InduMinerals supplies construction-grade wollastonite for: – Fibre-reinforced boards – Tile adhesives and joint fillers – Cement-based mortars and dry-mix systems – Lightweight or engineered construction composites Its acicular (needle-like) shape and thermal stability contribute to: – Dimensional control – Crack resistance and durability – Chemical stability and fire resistance Wollastonite supports low-VOC, sustainable, and performance-optimized building formulations.
RECOMMENDED GRADES FOR CONSTRUCTION USE
BLENDING WITH OTHER MINERALS
We assist with custom blends and granulometric matching to meet your performance and formulation needs.
Wollastonite can be blended with: – Dolomite (filler and pH balance) – Calcium carbonate (bulk extender) – Perlite / Vermiculite (lightweight systems)
PERFORMANCE ADVANTAGES IN CONSTRUCTION SYSTEMS
– Enhances crack resistance in adhesives, renders & mortars – Improves dimensional stability in fibre boards and panels – Supports thermal insulation in lightweight fillers – Increases mechanical strength and cohesion in tile adhesives – Contributes to fire resistance in boards and composites – Reduces shrinkage in cementitious systems
SUPPORT FOR BUILDING MATERIAL PRODUCERS
We provide: – Grade selection based on flowability, strength & setting time – Technical specifications & dry-mix performance guidance – Bulk supply available in bags or silo-compatible formats
