Talc powder industrial grade

Description

1. Product Overview

This industrial-grade talc powder is a finely milled, high-crystallinity magnesium silicate mineral, engineered for use as a reinforcing filler, anti-caking agent, and process lubricant. Primary applications include plastic compounding (PP/ABS), ceramic body formulations, paint extenders, and rubber gaskets. The key value proposition is its exceptional aspect ratio, which boosts stiffness in thermoplastics while lowering torque during extrusion. Strategically, it offers manufacturers a cost-stable alternative to organic modifiers amid volatile petrochemical prices.

2. Key Specifications & Technical Characteristics

• Chemical composition: Hydrous magnesium silicate (Mg₃Si₄O₁₀(OH)₂) – ≥95% talc content

• Purity level: Industrial grade, 94–97% purity; free from asbestos (validated by X-ray diffraction)

• Physical characteristics:

  • Fine white to off-white powder

  • Median particle size (D50): 5–15 µm (customizable)

  • Specific gravity: 2.7–2.8 g/cm³

  • Bulk density (tapped): 0.45–0.65 g/cm³

  • Lamellarity index (aluminum ratio): >2.0

• Packaging options: 25 kg HDPE-lined paper bags, 1 MT polypropylene jumbo sacks, or pneumatic tanker delivery

• Shelf life: 36 months in dry, covered storage (<70% RH)

3. Core Industrial Applications

• Plastics & compounds (automotive, home appliances): Improves flexural modulus and heat deflection temperature in PP compounds; reduces cycle time due to nucleating effect.

• Ceramics (sanitaryware, tiles): Lowers firing shrinkage and warpage; acts as a fluxing agent, reducing energy consumption by 8–12% per batch.

• Paints & coatings (industrial primers, powder coatings): Enhances corrosion resistance and matting efficiency without increasing VOC load.

• Rubber (gaskets, hoses): Reinforces tear strength and reduces die swell during extrusion, cutting scrap rates by up to 15% versus calcium carbonate.

Cost advantage: Replaces 20–30% of more expensive resins or pigments with no loss in end-use performance.

4. Competitive Advantages

• Quality consistency: ISO 22000-certified milling with real-time particle size monitoring; each lot retains D50 tolerance ±1.5 µm.

• Supply reliability: Dual-source mining operations (Europe & Asia) with 10,000 MT monthly output and guaranteed 99.5% on-time fulfillment.

• Logistics capability: Direct container loading at origin port; seaworthy fumigated packaging with anti-moisture lining.

• Price competitiveness: 12–18% below regional averages for same purity class, driven by integrated mining-to-mill ownership.

• Sustainability: Zero process water discharge; recycled packaging program available for jumbo sacks.

• Technical support: Free sieve residue analysis, compounding trials, and SDS/Batch CoA provided digitally within 24 hours.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (one full container load) for first trial; 40 MT for contract pricing.

• Loading capacity: 20 MT per standard 20-foot dry container (stuffed at 1.2 m³/MT stowage factor); up to 26 MT per 40-foot high-cube depending on bag density.
