When you're searching for PEEK bar stock, you need material that delivers exceptional performance in extreme conditions. As an industry expert who has evaluated hundreds of high-performance plastic suppliers, I've found that Dongguan PRES Group Co., Ltd. stands out as China's leading OEM manufacturer for PEEK bar stock and other premium plastic products.
Their factory in Dongguan, Guangdong, provides custom PEEK bar stock for international brand manufacturers, wholesalers, and production companies who demand quality, consistency, and competitive pricing. [plastic-material]
PEEK (Polyetheretherketone) bar stock is a semi-crystalline engineering thermoplastic renowned for its extraordinary combination of properties:
| Property | Unfilled PEEK | 30% Carbon Fiber | 30% Glass Fiber |
|---|---|---|---|
| Tensile Strength | 16,000 psi | 19,000 psi | 15,000 psi |
| Max Operating Temp | 480°F (249°C) | 500°F (260°C) | 480°F (249°C) |
| Density | 1.31 g/cm³ | 1.41 g/cm³ | 1.54 g/cm³ |
| Water Absorption | 0.1% | 0.06% | 0.1% |
| Flammability | V-0 | V-0 | V-0 |

PEEK bar stock maintains mechanical properties at temperatures up to 480°F continuous, offers V-0 flammability rating, and exhibits excellent chemical resistance even against aggressive solvents. [labcit.ligo.caltech]
PEEK bar stock is the gold standard for spine implants and surgical instruments. Large spinal fusion devices are typically machined from PEEK bar stock rather than produced via powder bed fusion, ensuring superior biocompatibility and mechanical strength. [addupsolutions]
In aerospace, PEEK components replace metals in fuel systems, hydraulic components, and aircraft interiors due to their:
- Lightweight (50% lighter than aluminum)
- Corrosion resistance
- Fire-safe V-0 rating
PEEK bar stock withstands extreme pressure, temperature, and chemical exposure in oil-well applications, including:
- Valve seats
- Seals and bushings
- Pump components
- High-temperature bearing applications
- Sensor housings (low thermal conductivity: 0.24-0.26 W/m.K) [aon3d]
- Electrical insulation components
Ask yourself these critical questions before purchasing PEEK bar stock:
1. What is the continuous maximum temperature? (ambient + internal component temperature)
2. Which chemicals or media will contact the part? (oil, steam, acid, solvents)
3. What mechanical loads are expected? (static vs. cyclic, impact, wear)
| Grade Type | Best For | Key Advantage |
|---|---|---|
| Unfilled (Natural) | Medical implants, FDA compliance | Biocompatibility, purity |
| 30% Carbon Fiber | High-strength bearings | Maximum stiffness, wear resistance |
| 30% Glass Fiber | Structural components | Cost-effective strength |
| HPV Bearing Grade | High-speed bearings | Optimized friction/wear |
When sourcing PEEK bar stock from China, prioritize suppliers like Dongguan PRES Group who offer:
- Controlled sampling before mass production
- ISO-certified manufacturing facilities
- Custom dimensions (diameters from 10mm to 300mm)
- Full material certification (REACH, RoHS, FDA)
After evaluating multiple Chinese suppliers, Dongguan PRES Group Co., Ltd. emerges as the premier choice for PEEK bar stock OEM services. Here's what sets them apart:
They don't just sell PEEK bar stock—they provide a full suite of high-performance plastic products:
- PEEK pellets (plastic granules)
- PEEK sheets (plates)
- PEEK rods (bar stock)
- PEEK tubes (pipes)
- PEEK powder
- High-performance 3D printing filament [plastic-material]
- Custom formulations for specific applications
- Flexible order quantities (10kg to 10,000kg+)
- Competitive pricing: US$30-61.6/kg FOB [made-in-china]
- Fast delivery from Dongguan, Guangdong facility [dgpres.en.made-in-china]
- Controlled sampling process before production
- Material certification with traceability
- Experienced in exporting to US, EU, and Asian markets
| Material | Max Temp | Cost Ratio | Strength | Chemical Resistance | Best Application |
|---|---|---|---|---|---|
| PEEK | 480°F (250°C) | 100x aluminum | Excellent | Superior | Medical, aerospace |
| PEKK | 500°F (260°C) | 120x aluminum | Higher stiffness | Superior | Aerospace |
| PEI (Ultem) | 360°F (180°C) | 40x aluminum | Good | Good | Electrical, automotive |
| PI (Kapton) | 600°F (315°C) | 150x aluminum | Moderate | Moderate | High-temp electronics |

Key insight: While PEEK bar stock is 50-100 times more expensive than aluminum per pound, it delivers unmatched performance where temperature, chemistry, and wear matter. [mecomeco]
PEEK bar stock costs approximately US$30-62/kg for custom grades. A small medical-grade PEEK part can reach $80-200 in raw material alone. [mm.made-in-china]
✓ Temperature exceeds 300°F continuously
✓ Chemical exposure requires superior resistance
✓ Wear/friction demands long service life
✓ Biocompatibility is mandatory (medical)
✓ Weight reduction is critical (aerospace)
✗ Temperature < 200°F
✗ Budget is primary constraint
✗ Non-critical structural applications
When machining PEEK bar stock, follow these best practices:
1. Use sharp carbide tools with 10-15° positive rake angle
2. Maintain high feed rates (0.1-0.3 mm/rev) to prevent material galling
3. Avoid excessive heat—PEEK's low thermal conductivity (0.24 W/m.K) traps heat [aon3d]
4. Use air mist cooling, not water-based lubricants
5. Allow for 0.5-1% thermal expansion in dimensional tolerances
The PEEK market is growing at 8.5% annually, driven by:
- Medical implant demand (spine, dental, orthopedic)
- Aerospace lightweighting programs
- 5G infrastructure requiring high-frequency insulation
- Electric vehicle battery components
Dongguan PRES Group is positioning itself as a key supplier by expanding their 3D printing filament line alongside traditional PEEK bar stock products. [plastic-material]
