• Coloring Agent: It provides high opacity and improves the color index of plastics.

3. Inks

• Print Quality: Lithopone powder is utilized in ink formulations to enhance brightness and print quality.
• Stability: It helps in maintaining the consistency and stability of ink during storage.

4. Rubber

• Anti-tack Properties: Lithopone powder is effective in rubber applications to reduce stickiness.
• Reinforcement: Improves the mechanical properties of rubber products.

5. Ceramics

• Glazing Agent: In ceramics, lithopone powder is used as a glazing agent to provide a glossy finish.
• Enhancement of Brightness: It contributes to the aesthetic appeal of ceramic products.

Purchasing Considerations for Lithopone Powder

When considering the purchase of lithopone powder, several key factors should be kept in mind to ensure optimal performance and quality.

1. Quality Specifications

• Purity Levels: Look for a supplier that offers high purity lithopone powder, usually 95% or higher, to ensure better performance in applications.
• Particle Size: Different applications may require different particle sizes; ensure that you specify your needs to the supplier.

2. Supplier Reliability

• Reputation: Choose suppliers with a proven track record in providing high-quality lithopone powder.
• Certifications: Verify if suppliers have industry certifications for quality assurance.

3. Cost Considerations

• Bulk Purchase Discounts: If you require large quantities, inquire about discount rates for bulk purchases.
• Comparative Pricing: Compare prices from multiple suppliers to ensure you’re getting a fair deal without compromising quality.

4. Technical Support

• Customer Service: Opt for suppliers that offer comprehensive customer support, including technical advice for application.
• Sample Availability: Request samples to evaluate the product before committing to a large order.

5. Regulatory Compliance

• Safety Data Sheets (SDS): Ensure that the lithopone powder complies with local regulations and that the SDS is available for safety compliance.
• Environmental Considerations: Look for eco-friendly options that meet environmental regulations.

Common Confusions and Solutions

1. What is the difference between lithopone powder and titanium dioxide?

   • Lithopone is generally less expensive than titanium dioxide and offers good UV resistance but may not have the same opacity. Use lithopone when cost is a concern or in applications where absolute whiteness is less critical.

2. Can lithopone powder be used in food-grade applications?

   • Most lithopone powders are not food-grade. Verify with manufacturers for food-grade certification if required.

3. How to store lithopone powder?

   • Store in a cool, dry place and keep away from direct sunlight to prevent degradation of quality.
