About Calcium Carbonate Powder For PVC Profiles

In PVC products, CaCO3 is added for two reasons: to reduce the cost and to provide functional properties. Viscosity of PVC compound is important from a processing point of view. It increases with the addition of filler because CaCO3 does not melt during processing.

Superior Whiteness and Brightness

With whiteness levels of 98% or higher and brightness between 95% and 98%, this Calcium Carbonate Powder visibly improves the appearance of PVC profiles. Its fine particle distribution ensures enhanced coverage and a smooth finish, supporting premium product aesthetics for industrial applications.

Optimized Filler for PVC Profiles

The powder serves as a high-performance filler in the manufacture of PVC profiles. Its unique combination of low oil absorption, controlled particle size, and substantial calcium content strengthens physical properties and increases production efficiency in various industries.

Quality Adherence and Non-Toxicity

Tested to meet ISI and ASTM standards, this product is safe, non-poisonous, and odorless, making it ideal for professional PVC processing environments. Its industrial-grade purity and consistent composition ensure reliable integration into manufacturing workflows.

FAQs of Calcium Carbonate Powder For PVC Profiles:

Q: How is Calcium Carbonate Powder used as a filler in PVC profiles?

A: Calcium Carbonate Powder is incorporated during the mixing stage of PVC profile manufacturing. It acts as a filler, optimizing mechanical properties, reducing material costs, and enhancing the whiteness and surface finish of the final PVC profile.

Q: What are the primary benefits of using this powder in PVC profile production?

A: Key benefits include improved whiteness, uniform texture, better processing stability, increased hardness, and cost-effective production. The powders fine consistency and high calcium content also boost the strength and durability of PVC profiles.

Q: When should the powder be stored or handled in a specific way?

A: It should be stored in a dry, room temperature environment to maintain its low moisture content and prevent clumping. Handling requires standard PPE to avoid dust inhalation, as the product is fine and granular.

Q: Where is this Calcium Carbonate Powder manufactured and supplied?

A: This powder is produced in India and is available through manufacturers, suppliers, and wholesalers nationwide. Its quality conforms to local and international standards such as ISI and ASTM.

Q: What process ensures the powders specified particle size and purity?

A: The powder undergoes controlled grinding and classification techniques to achieve the required D97 particle size range (10-25 microns) and maintains purity between 96% and 99%, ensuring consistent performance in industrial applications.

Q: Is the powder safe and environmentally friendly for industrial use?

A: Yes, it is non-poisonous, odorless, and classified as an inorganic compound with no hazardous properties, making it safe for industrial environments. The powder is insoluble in water and does not pose risks during normal use.
