PEEK Engineering Plastic Resin (PEEK-20)

Description

1. Product Overview

PEEK-20 is a high-performance, semi-crystalline engineering thermoplastic resin, reinforced with 20% carbon fiber for enhanced mechanical strength and thermal stability. Primarily used in aerospace, automotive, oil & gas, and medical device manufacturing, it enables precision components that must withstand extreme loads, high temperatures, and aggressive chemical environments. Its key value proposition lies in replacing metals at up to 70% weight reduction while maintaining comparable stiffness and fatigue resistance. Strategically, PEEK-20 is critical for industries transitioning toward lightweighting and operational efficiency under the most demanding regulatory standards.

2. Key Specifications & Technical Characteristics

• Chemical composition: Polyetheretherketone (PEEK) with 20% carbon fiber reinforcement by weight

• Purity / Grade: Virgin-grade; no regrind; meets ISO 23936-1 for oil & gas and USP Class VI for biocompatibility

• Physical characteristics:

  • Form: Cylindrical pellets (2.5–3.5 mm diameter)

  • Color: Black (carbon fiber pigmentation)

  • Density: 1.40 g/cm³ (ASTM D792)

  • Melt flow index: 8–12 g/10 min (380°C / 5 kg)

  • Tensile strength: ≥200 MPa (ASTM D638)

  • Glass transition temperature (Tg): 143°C

  • Melting temperature (Tm): 343°C

  • Continuous service temperature: 260°C

• Packaging options: 25 kg sealed moisture-barrier bags; 500 kg octabins; 1,000 kg FIBCs with desiccant liner

• Shelf life: 24 months when stored below 40°C in original unopened packaging with <15% relative humidity

3. Core Industrial Applications

• Aerospace & Defense: Structural brackets, fuel system components, and connector housings. Outperforms aluminum — eliminates galvanic corrosion, reduces machining waste, and passes 60-second vertical burn test (FAR 25.853).

• Automotive (EV & motorsport): Thrust washers, seal rings, and transmission components. Outperforms PEEK-unfilled — 2x higher compressive strength and lower thermal expansion, enabling tighter tolerances under high-speed, high-torque EV drivetrains.

• Oil & Gas (downhole): Backup rings, valve seats, and compressor plates. Outperforms PAI and PPS — superior resistance to H₂S and sour gas, with less than 0.1% weight gain after 1,000 hours in 150°C brine.

• Medical instruments (non-implantable): Sterilizable surgical tool handles and guidewires. Outperforms stainless steel — reusable through 3,000+ autoclave cycles without dimension change or loss of grip texture.

4. Competitive Advantages

• Quality consistency: Lot-to-lot viscosity variation <3% (ISO 1133). Each shipment includes full COA with rheology, ash content, and mechanical test data.

• Supply reliability: Dual-source manufacturing (EU + Asia) with 12-month rolling forecast buffer stock. Zero supply disruptions reported to any client in the past 36 months.

• Logistics capability: Global hubs in Rotterdam, Houston, and Shanghai offer 48-hour emergency dispatch for production-critical orders.

• Price competitiveness: 8–12% below European and U.S. virgin PEEK-20 averages at comparable spec, enabled by direct polymer-to-compound integration.

• Sustainability: 100% process scrap recaptured into non-critical industrial grades. Carbon footprint 18% lower than industry average (mass balance approach, ISO 14067).

• Technical support: In-house application engineers provide molding simulations, drying protocols, and failure analysis within two business days.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT (20 metric tons) per product grade per shipment

• Loading capacity (MT per container):

  • 20-foot dry container: 18 MT net (max palletized)

  • 40-foot high-cube container: 24 MT net (optimized bulk packing)

  • *Note: For 20 MT exactly, use a 40-foot HC at 20 MT to avoid overloading 20-foot container legal limits.*
