High Tensile PAN Based Carbon Fiber Yarn(HTPAN-12K)

Description

1. Product Overview

The High Tensile PAN Based Carbon Fiber Yarn (HTPAN-12K) is a continuous-strand, polyacrylonitrile-derived carbon fiber filament bundle containing 12,000 individual filaments per tow, engineered for superior tensile strength and modulus. Its primary industrial use lies in high-performance composite manufacturing for aerospace, automotive, and wind energy sectors, where weight reduction and structural integrity are mission-critical. The key value proposition is an exceptional strength-to-weight ratio combined with fatigue resistance, enabling lightweighting without compromising safety or durability. Strategically, this product is vital for industries transitioning to net-zero emissions through electrification and fuel efficiency, as carbon fiber composites directly reduce operational energy demand.

2. Key Specifications & Technical Characteristics

• Shelf Life: 36 months from date of manufacture when stored in original unopened packaging at 20°C ± 5°C, <60% RH, away from UV exposure

3. Core Industrial Applications

Why it performs better: The 12K tow size balances processability (easier to weave, braid, or filament wind than 24K/50K) with layup speed (faster than 1K/3K). PAN-based chemistry provides higher carbon yield and fewer surface defects than pitch-based alternatives, translating to higher real-world tensile strength in finished laminates.

4. Competitive Advantages

• Quality consistency: Every production lot is tested for tensile strength, modulus, and tex variation; COA (Certificate of Analysis) provided with each shipment. CV (coefficient of variation) for tensile strength <5% – exceeding ISO 11566 standards.

• Supply reliability: Vertically integrated manufacturing from precursor polymerization to oxidation/carbonization; buffer stock maintained at three regional warehouses (Asia, Europe, North America).

• Logistics capability: In-house hazardous materials classification (UN no. 3161) and export documentation; average lead time 14 days EXW for orders above 20 MT.

• Price competitiveness: Direct-from-factory pricing with no distributor mark-up; volume discounts for annual framework agreements.

• Sustainability: Production facilities run on 35% renewable energy; zero liquid discharge in surface treatment; carbon footprint data available upon request.

• Technical support: Free pre-sales compatibility testing with your resin system; failure analysis and layup simulation support for qualified buyers.
