Kaolin for Tiles

Tile production requires raw materials that provide plasticity during pressing or extrusion, good green strength for conveyor handling, and dimensional consistency through drying and firing.

UT-WHITE works as a clay and silica component (SiO₂ 72.2%) in the tile body mix, improving workability during pressing and supporting fired body strength. Its fine D50 4.571 µm supports even compaction during press forming. UT-WHITE is well suited for glazed wall and floor tiles where the body is covered by glaze — dimensional consistency and green strength matter more than body color.

  • Prevents warping and bending
  • Suitable for glazed wall tiles and floor tiles where body color is not critical
  • Compatible with fast-firing cycles

Performance Characteristics

Press Compaction Aid

Fine D50 4.5 µm supports uniform compaction during dry pressing, reducing density variations and defects in green tile before firing.

Dimensional Consistency

Controlled shrinkage during drying and firing helps tiles stay square and flat (planarity) — critical for wall and floor tile installation tolerances.

Glazed Tile Compatible

With Fe₂O₃ ~1.78%, UT-WHITE suits glazed wall tiles and floor tiles where the glaze covers the body — a practical choice over more expensive low-iron grades.

Recommended Grades

Grades selected for floor and wall tile production, balancing fired whiteness, mechanical strength, and dimensional stability at scale.

UT-WHITE High Brightness Kaolin

UT-WHITE

UT-WHITE is a natural hydrous kaolin with 96.6% ISO brightness, ground to D50 4.571 µm using alumina ball milling to prevent iron contamination. Contributes plasticity control and whiteness as a blend component in ceramic tile body formulations.
