Talc Powder ACS

Product Overview

Talc Powder ACS is a high-purity, finely milled mineral composed primarily of magnesium silicate (Mg3Si4O10(OH)2). Manufactured to meet stringent ACS Reagent Grade specifications, this product ensures low trace metal content and strictly controlled particle size distribution. Unlike technical grade alternatives, ACS Grade Talc is suitable for critical analytical applications and sensitive industrial formulations where impurities could compromise results or product integrity.

This hydrophobic, white to off-white powder exhibits excellent lubricity, chemical inertness, and thermal stability. It is widely used as a superior filler in polymer engineering, a carrier in chemical processing, and a reference standard in laboratory environments. With a typical assay of 99.7% and rigorous testing for heavy metals (such as Lead and Arsenic), Alliance Chemical guarantees a product that supports precise quality control workflows and high-performance manufacturing standards.

• Coatings & Paints: Enhances rheology, corrosion resistance, and matting properties in industrial primers and topcoats.
• Ceramics: Used as a flux to control thermal expansion and improve the electrical properties of ceramic bodies.
• Industrial Lubrication: Serves as a dry lubricant and anti-sticking agent in manufacturing processes involving rubber and molding.

Safety & Handling

While Talc is chemically stable, proper safety measures are required during handling to manage dust generation. Store in a cool, dry, well-ventilated area away from incompatible materials. Operators should utilize appropriate Personal Protective Equipment (PPE), including dust masks or respirators (N95 or higher recommended for fine particulates), safety glasses, and gloves. Avoid inhalation of dust. Refer to the Safety Data Sheet (SDS) for comprehensive hazard information and emergency procedures.
