Talcum Powder

Talc, or talcum, is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powdered form, often combined with corn starch, is used as baby powder. This mineral is used as a thickening agent and lubricant. It is an ingredient in ceramics, paints, and roofing material. It is a main ingredient in many cosmetics.
It occurs as foliated to fibrous masses, and in an exceptionally rare crystal form. It has a perfect basal cleavage and an uneven flat fracture, and it is foliated with a two-dimensional platy form.

Agriculture Gypsum

Agricultural Gypsum is a high-quality fertilizer grade gypsum derived from naturally occurring mineral sources. It is widely used in various agricultural applications, including as a carrier for composting ingredients, horticultural dressings, and soil improver for saline soils and land reclamation.

Product Benefits

Naturally occurring gypsum with high purity.
Particle size distribution optimized for agricultural applications.
