Product Usage Example

Usage of DIACAL TDD in conveyor belts
Rubber matrix is generally softer than inorganic fillers, for example calcium carbonate, addition of fillers into the rubber matrix can increase abrasion resistance, protecting the rubber matrix from friction wear. If filler particles do not bind well to the rubber matrix, it becomes loose and will fall out, exposing the rubber making it a weak point. DIACAL TDD nano calcium carbonate is surface treated is resin acid, have good wetting ability to aid with compounding and mixing of rubber with calcium carbonate particles, particles are small and can spread evenly into the matrix, increasing lifespan of conveyor belts.


Usage of DIACAL TDD used in ink
DIACAL TDD is surface treated with resin acid and is compatible with many ink formulations. Addition of DIACAL TDD nano calcium carbonate as fillers to ink can modulate consistency, viscosity and rheology properties. DIACAL TDD is highly dispersible, have low bulk density, and have good hiding power.
