Virtual International offers high-grade Calcium Sulphate (CaSO4), a naturally occurring inorganic salt renowned for its widespread utility across various industrial sectors. We process our Calcium Sulphate from select gypsum deposits or as a synthetic byproduct, ensuring exceptional purity, consistent particle sizing, and superior performance characteristics. Available in multiple forms, including dihydrate (gypsum), hemihydrate (Plaster of Paris), and anhydrite, our product meets stringent technical specifications and regulatory standards. Its unique binding, filling, and nutrient properties make it indispensable in construction, food, pharmaceutical, and agricultural applications. Industries globally rely on our Calcium Sulphate to enhance material strength, improve product texture, deliver essential nutrients, and act as an inert filler. We guarantee a reliable supply of premium Calcium Sulphate with efficient and timely delivery, fostering improved product quality and operational efficiency for our partners.

Key Features & Industrial Benefits

• Excellent Binder & Setting Properties: Hemihydrate forms (Plaster of Paris) exhibit rapid setting and hardening characteristics, crucial for construction and molding applications.
• Inert Filler & Extender: Acts as an effective, non-reactive filler in plastics, paper, paints, and rubber, reducing costs and improving physical properties.
• Natural Nutrient Source (Ca & S): Provides readily available calcium and sulfur for plants, vital for soil conditioning and crop nutrition.
• High Purity Grades Available: We offer specific grades for sensitive applications, including food and pharmaceutical industries, meeting strict purity standards.
• Consistent Particle Size: Ensures homogeneous mixing and predictable performance in formulations, from fine powders to coarser granules.
• Non-Toxic & Safe: Considered a safe and environmentally friendly compound, suitable for various applications including those with direct human or animal contact.
• Thermal Stability: Exhibits good thermal stability, making it suitable for applications requiring processing at elevated temperatures.
• Reliable Supply Chain: Virtual International maintains a robust global supply chain, ensuring consistent availability and timely delivery to support uninterrupted production schedules.

Versatile Industrial Applications

Construction Industry:

• Drywall & Plaster: The primary component of gypsum Drywall panels and various plaster products due to its excellent fire resistance and structural properties.
• Cement & Concrete: Used as a retarder in Portland cement to control setting time and prevent flash setting. Gypsum is also incorporated into some specialty mortars and renders.
• Flooring Compounds: Utilized in self-leveling floor screeds and underlayments.

Food & Pharmaceutical Industries:

• Food Additive (E516): Acts as a firming agent, dough conditioner, yeast food, and calcium supplement in baked goods, tofu, beer, and dairy products.
• Pharmaceutical Excipient: Employed as a tablet diluent, binder, or calcium source in pharmaceutical formulations.
• Dental Impressions: Hemihydrate forms are used to create dental molds due to their precise setting properties.

Agriculture & Soil Conditioning:

• Soil Amendment: Gypsum improves soil structure, reduces sodium toxicity, and enhances water infiltration and aeration, particularly in clayey soils.
• Fertilizer: Provides essential calcium and sulfur, vital macronutrients for crop health and yield, without altering soil pH significantly.

Plastics, Paints & Coatings:

• Filler & Extender: Reduces production costs and improves physical properties like stiffness, impact resistance, and opacity in plastics (e.g., PVC), paints, and coatings.

Paper & Pulp Industry:

• Filler & Pigment: Enhances brightness, opacity, and smoothness of paper, while also reducing manufacturing costs.
