Technical Strengths: Why Choose Industrial Grade Talcum Powder?

High Purity & Consistency: Advanced beneficiation yields talcum powder with up to 99% purity, ensuring minimal contaminants for critical polymer or rubber operations.
Particle Engineering: Jet milling produces ultra-fine, narrow-distribution particles (d₅₀ as low as 2μm for steatite powder), maximizing surface area and compatibility.
Superior Brightness & Whiteness: ISO brightness > 90% makes it ideal for high-gloss plastics and UV-resistant coatings.
Thermal Stability: Melting point over 1500°C and low thermal expansion protect plastic and rubber integrity during extrusion, molding, and end-use.
Chemical Passivity: Acid/alkali resistance, preventing corrosion in water-pipe, petrochemical, and chemical processing applications.
ISO, ANSI, FDA Certified: Global compliance for food, potable water, pharmaceutical, and advanced industrial uses (ISO 3262-10:2020, FDA).

Professional FAQs – Talcum Powder, Steatite & Plain Talcum Powder for Industry

Q1: What’s the main chemical composition of talcum powder used in plastics? A1: Primarily magnesium silicate (Mg3Si4O10(OH)2), enriched for uniform phase and minimal iron content, optimizing for high molecular weight polymer blends.

Q2: How is “steatite powder” technically different from plain talcum powder? A2: Steatite powder is an ultra-refined, denser talc with higher purity (98–99%) and finer d₅₀ (<8μm), ideal for premium plastics, ceramics, and high-dielectric applications.

Q3: What are the valid ISO and ANSI standards for industrial talcum powder? A3: ISO 3262-10 governs technical talc; ANSI B74 relates to abrasive compatibility. Food safety grades must also comply with FDA US-21CFR184.1795.

Q4: What are typical particle sizes required for high-gloss plastic coatings? A4: Premium grades require d₅₀ between 2 and 8μm, measured via laser diffraction, for optimal surface finish and anti-sag performance in coatings.

Q5: Does talcum powder cause yellowing or mechanical degradation? A5: Quality, low-iron talcum powder is chemically inert; instead, it stabilizes color and mitigates oxidative aging in both thermoplastics and elastomers.

Q6: What certifications should compliant talc products possess for potable water or food contact? A6: FDA, ISO 3262-10, and USP/EP certificates; low heavy metals per EN 71-3, and migration limits as tested by independent SGS labs.

Q7: Can Shun Shun Mining customize hydrophobic or specialty talcum powder grades? A7: Yes, customized with silicon, dioctyl, or coupling agent treatments on demand—ideal for composite resin and water-repellent applications.
