Minerals Used for Plastic & Polymer

Plastics and polymers are essential materials used across industries, from packaging and automotive to construction and consumer goods. To enhance their strength, durability, and processing efficiency, mineral fillers such as Talc, Calcium Carbonate, and Mica are widely used. These minerals improve mechanical properties, reduce production costs, and enhance thermal stability.

At Ashok Minerals, we supply high-quality Talc, Calcium Carbonate, and Mica, ensuring superior performance in plastic and polymer applications. Below is a detailed breakdown of their properties and uses.

1. Talc

Chemical Properties

• Chemical Formula: Mg₃Si₄O₁₀(OH)₂
• Platy, hydrophobic structure with excellent thermal and chemical stability.
• High aspect ratio, improving mechanical properties in polymers.

Uses in Plastic & Polymer

• Improves stiffness, impact resistance, and dimensional stability in plastic products.
• Enhances heat resistance and reduces shrinkage in polymer formulations.
• Acts as a reinforcing agent in polypropylene (PP), polyethylene (PE), and PVC.

How Talc is Used in Plastic & Polymer

Talc is widely used in automotive plastics, packaging, household goods, and engineering plastics. It improves rigidity, scratch resistance, and processing efficiency, making plastics more durable and cost-effective.

Ashok Minerals supplies high-purity talc that enhances polymer performance, ensuring superior quality in manufacturing.

2. Calcium Carbonate (Calcite) – Precipitated, Coated, and Ground

Chemical Properties

• Chemical Formula: CaCO₃
• High brightness, fine particle size, and excellent dispersibility.
• Neutral pH, ensuring compatibility with most polymer formulations.

Uses in Plastic & Polymer

• Acts as a cost-effective filler, reducing raw material costs.
• Improves tensile strength, opacity, and surface finish.
• Enhances thermal conductivity, making polymers more heat-resistant.

How Calcium Carbonate is Used in Plastic & Polymer

Precipitated Calcium Carbonate (PCC) is used for high-performance applications, while Ground Calcium Carbonate (GCC) is preferred for cost-effective bulk fillers. Coated Calcium Carbonate improves dispersion in polypropylene (PP), polyethylene (PE), PVC, and rubber.

At Ashok Minerals, we provide high-quality PCC, GCC, and Coated Calcium Carbonate, ensuring better processing, durability, and mechanical properties in plastic manufacturing.

3. Mica

Chemical Properties

• Chemical Formula: KAl₂(AlSi₃O₁₀)(OH)₂
