ULTRAFINE WOLLASTONITE FOR HIGH-TECH APPLICATIONS

High aspect ratio. Submicron performance. Advanced functionality.

Engineered for ceramics, coatings, polymers, and friction materials where ultrafine reinforcement is critical.

InduMinerals offers a premium ultrafine wollastonite with: – D50 90 – Aspect ratio > 25:1 Designed for: – Advanced ceramics – High-end coatings and paints – Friction materials (e.g., brakes, clutches) – High-performance polymer composites Key benefits: – Exceptional dispersion at low loading levels – Enhanced surface activity and reinforcement – Crack resistance and thermal shock performance – Ideal for fiber-like reinforcement in sensitive formulations

TYPICAL APPLICATIONS & BENEFITS

  • Reinforces fine ceramics, porcelain, and advanced bodies

  • Improves thermal shock resistance and green body strength

  • Allows lower firing temperatures with high whiteness

  • Ideal for high-end tiles, sanitaryware, and insulators

  • Suitable for engineering plastics, filled thermoplastics, and composite compounds

  • Enhances modulus, dimensional control, and surface finish

  • Fiber length and ultrafine size enable high surface reinforcement

  • Used in premium brake systems, clutches, and composite pads

  • Provides even fiber dispersion and abrasion resistance

  • Reduces noise, improves pad stability under heat cycles

  • Functions as a functional extender and matting agent

  • Improves film hardness, anti-crack performance, and chemical resistance

  • Low oil absorption, excellent for low-VOC and high-solid systems

PACKAGING & STORAGE

  • Supplied in 25 kg multi-layer bags or high-purity bulk bags
     

  • Product is moisture-controlled, available in palletized or sealed units

COAs, detailed morphology (SEM), and custom packaging available upon request.
