Product details

Product Composition

Material base polymer:

PEEK polymer (as the main substrate/matrix material)

Functional additives (10% each):

Polytetrafluoroethylene (PTFE)

▪ Function: significantly reduce the friction coefficient and improve wear resistance

Graphite (Graphite)

▪ Function: provide self-lubrication and enhance high temperature stability

Carbon Fibres (Carbon Fibres)

▪ Function: improve mechanical strength, stiffness and dimensional stability

Performance Characteristics

1. Superior Wear Resistance

10% graphite: Provides a solid lubricating layer to reduce surface wear

10% carbon fiber: Enhances matrix hardness and resists abrasive erosion

Result: Significantly extends the service life of bearings/sliding parts

2. Ultra-Low Friction Coefficient

10% PTFE: Forms a self-lubricating film on the friction surface, reducing the dynamic friction coefficient by 40-60%

Result: Reduces energy consumption and heat accumulation, suitable for high-speed sliding scenarios

3. Enhanced Strength & Stiffness

10% carbon fiber： Improves tensile strength (+30% or more) and elastic modulus

Result: Load-bearing capacity is better than pure PEEK, resists deformation and fatigue

4. High Dimensional Stability Stability)

Carbon fiber + graphite composite network: inhibit thermal expansion (reduced linear expansion coefficient)

Result: precision parts maintain tolerance accuracy (±0.05mm level) under temperature fluctuations

5. High-Temperature Performance

Base material PEEK temperature resistance 260℃ + additive synergy:

PTFE guarantees high-temperature lubricity (up to 250℃)

Graphite improves thermal conductivity and reduces local overheating

Result: maintain more than 80% of mechanical properties under 200℃ working conditions

Advantages

1. Triple synergistic wear resistance

10% carbon fiber: Strengthen the deformation resistance of the matrix

10% graphite: Continuously provide a self-lubricating layer

10% PTFE: Significantly reduce the dynamic friction coefficient

→ Wear rate is reduced by more than 85% compared to pure PEEK

2. Zero lubrication operation capability

Additives synergistically form a permanent lubricating film

Eliminating grease pollution (applicable to medical/food grade scenarios)

3. High load and high temperature stability

Limit PV value＞3.5 MPa·m/s(increased by 337%)

-50℃~+250℃ Maintain dimensional accuracy (expansion coefficient <3×10⁻⁵/K)

4. Professional scenario customization

Specially optimized for bearings/sliding parts:

Anti-fretting wear

FAQ

Q: Compared with unfilled pure PEEK, what are the advantages of PEEK5600LF30?

A: Adding 10% carbon fiber + 10% graphite + 10% PTFE triple reinforcement, the compressive strength is increased by 40%, and the wear resistance is increased by 50%, which is more suitable for high-load bearing applications.

Q: What is the difference compared with ordinary carbon fiber filled PEEK?

A: Ordinary products only enhance rigidity, while PEEK5600LF30 adds PTFE+graphite, which reduces the friction coefficient by 35%, achieving self-lubrication and zero-stuttering operation.

Q: Compared with ceramic-based bearing materials, what are your advantages?

A: Ceramics are brittle and expensive, PEEK5600LF30 is 60% lighter, more resistant to chemical corrosion (acid, alkali, solvent), and 200% more cost-effective.

Q: How does it compare with stainless steel bearings?

A: Stainless steel needs regular oiling and maintenance. PEEK5600LF30 has a PTFE+graphite self-lubricating formula that extends its life by 3 times, is maintenance-free and saves costs.

Q: Compared with graphite-based materials, what breakthroughs are there in performance?

A: Graphite materials have weak mechanical strength. PEEK5600LF30 has a carbon fiber reinforced matrix, which increases its deformation resistance by 70% and achieves dimensional stability of ±0.02mm.

Q: What are the advantages compared with single-additive PEEK (such as PTFE only)?

A: The performance of a single additive is limited. PEEK5600LF30 has a triple compound formula: carbon fiber pressure bearing + graphite lubrication + PTFE friction reduction, and the overall performance is improved by 55%.

Q: Compared with engineering plastics such as nylon (PA66)?

A: Nylon is only resistant to 120°C, while PEEK5600LF30 is resistant to 260°C. Its strength retention rate at high temperatures exceeds 90%, making it suitable for extreme working conditions.

Q: What are the core differences compared to metal materials?

A: Metals are prone to corrosion and are heavy. PEEK5600LF30 is lightweight (density 1.45g/cm³) and has electrical insulation properties, eliminating the risk of current corrosion.

Q: What is the difference compared to ordinary plastics (such as PP/PE)?

A: Ordinary plastics have low hardness (Rockwell hardness <100), while PEEK5600LF30 has a hardness of 110 HRR, is wear-resistant and scratch-resistant, and has an 8-fold increase in load-bearing capacity.

Q: Compared with other special engineering plastics (such as PPS/PI), what is the cost-effectiveness?

A: PPS/PI is expensive (about 2 times), PEEK5600LF30 achieves 30% cost optimization with the same level of performance and has better fatigue resistance.
