professional Precipitated Calcium Carbonate Manufacturer

Product Description

TDD is our precipitated calcium carbonate coated with resin acid, with uniformed 50 nm primary particles, specifically designed for

enhanced compatibility with organic materials. Surface treated calcium carbonate provides better mixing properties when added to

organic materials during production. TDD is designed to be used in rubber, paint, ink and etc.

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.
