Functional Fillers
For applications requiring specific performance characteristics, our functional fillers deliver value through controlled rheology, thermal stability, barrier properties, and optical effects.
Overview
Functional fillers go beyond simple cost reduction. They are selected for the measurable performance they bring to a formulation. ROCC Global sources advanced mineral and synthetic fillers for coatings, cosmetics, composites, and engineered plastics. Whether the requirement is for nano-scale calcium carbonates, synthetic mica, or high-strength glass microspheres, we identify the right grade from the right source and manage delivery to your production schedule.
Commonly Sourced Materials
Fluorphlogopite Synthetic Mica
High-purity synthetic fluorine mica with thermal stability above 1000°C, used as a pearlescent pigment substrate and high-temperature insulator.
Sericite
Fine-grained muscovite mica with aspect ratio 20 to 80, used for barrier performance in coatings and soft-focus effects in cosmetics.
Nano Calcium Carbonates
Precipitated nano-scale calcium carbonate below 100 nm, providing thixotropy and mechanical reinforcement in sealants, adhesives, and PVC compounds.
Titanium Dioxide
Pre-eminent white pigment with refractive index 2.70 for rutile, delivering unmatched opacity and brightness in coatings, plastics, and inks.
Hollow Glass Beads
Engineered borosilicate microspheres with true density 0.15 to 0.60 g/cm³, used for weight reduction in composites, coatings, and oil well cement.
Glass Flakes
High-aspect-ratio C-glass and E-glass platelets providing a tortuous path barrier in anti-corrosion coatings for marine and industrial infrastructure.
