PEEK 30% Glass Filled Sheets are high-performance engineering plastic sheets made from polyether ether ketone (PEEK) reinforced with approximately 30% glass fiber. Compared with unfilled PEEK, 30% glass-filled PEEK offers increased stiffness, improved dimensional stability, higher resistance to creep, and enhanced mechanical performance under load.
Because of its combination of mechanical strength, chemical resistance, wear resistance, high-temperature capability, and electrical insulation properties, PEEK 30% glass-filled sheet is widely considered for demanding applications in aerospace, semiconductor equipment, chemical processing, industrial machinery, automotive systems, and precision engineering.
What Is PEEK 30% Glass Filled Sheet?
PEEK, or polyether ether ketone, is a high-performance thermoplastic known for its excellent mechanical, thermal, chemical, and electrical properties.
When approximately 30% glass fiber is incorporated into the PEEK resin, the resulting material has improved rigidity and dimensional stability compared with virgin PEEK.
The glass fiber reinforcement is particularly useful when a component must maintain its shape and mechanical performance under continuous loading, elevated temperatures, or demanding operating conditions.
In simple terms:
PEEK 30% Glass Filled Sheet = PEEK resin + approximately 30% glass fiber reinforcement for improved stiffness, strength, dimensional stability, and creep resistance.
The exact properties depend on the material manufacturer, grade, processing method, and formulation. For critical applications, customers should always verify the manufacturer’s technical data sheet and material certification.
Key Features of PEEK 30% Glass Filled Sheets
PEEK 30% glass-filled sheets offer several properties that make them suitable for demanding industrial applications:
1. High Mechanical Strength
Glass fiber reinforcement significantly improves the stiffness and mechanical performance of PEEK compared with unfilled grades.
This makes 30% glass-filled PEEK suitable for structural and load-bearing components.
2. Excellent Dimensional Stability
Glass fiber reinforcement helps reduce deformation caused by mechanical loads and temperature changes.
This is particularly important for precision components requiring tight dimensional control.
3. Improved Creep Resistance
PEEK 30% GF can provide improved resistance to long-term deformation under mechanical load compared with unfilled PEEK.
This makes it suitable for components that remain under continuous stress.
4. High-Temperature Performance
PEEK is a high-temperature engineering thermoplastic capable of maintaining useful mechanical properties at elevated temperatures.
The appropriate operating temperature depends on the specific grade, load, environment, and component design.
5. Excellent Chemical Resistance
PEEK offers resistance to many chemicals, including many oils, fuels, solvents, and aggressive industrial chemicals.
However, chemical compatibility should always be evaluated under the actual concentration, temperature, exposure time, and mechanical conditions.
6. Wear and Abrasion Resistance
PEEK provides good wear resistance for applications involving friction and mechanical movement.
It can be used for bushings, wear rings, bearings, guides, and other engineered components.
7. Electrical Insulation Properties
PEEK is an electrical insulating engineering thermoplastic and can be considered for suitable electrical and electronic components.
However, 30% glass-filled PEEK should not automatically be specified as an electrical insulation material without checking the required dielectric and electrical properties of the exact grade.
PEEK 30% Glass Filled vs. Virgin PEEK
One of the most common material-selection questions is whether to use virgin PEEK or glass-filled PEEK.
| Property | Virgin PEEK | PEEK 30% Glass Filled |
|---|---|---|
| Reinforcement | None | Approx. 30% glass fiber |
| Stiffness | Excellent | Higher |
| Dimensional Stability | Excellent | Improved |
| Creep Resistance | Excellent | Improved |
| Mechanical Strength | High | Higher in many conditions |
| Wear Resistance | Excellent | Excellent |
| Chemical Resistance | Excellent | Excellent |
| Electrical Insulation | Good | Good, grade dependent |
| Precision Components | Excellent | Excellent for rigid components |
| Typical Use | General high-performance applications | High-load and dimensionally demanding applications |
Which PEEK grade should you choose?
Choose virgin PEEK when you need a balance of mechanical properties, chemical resistance, toughness, and electrical performance without fiber reinforcement.
Choose 30% glass-filled PEEK when higher stiffness, dimensional stability, and resistance to creep under load are more important.
The final selection should be based on the actual operating temperature, load, friction, chemical environment, dimensional requirements, and electrical specifications.

Can PEEK 30% Glass Filled Be Used as an Insulating Material?
Yes, PEEK 30% glass-filled material can be used for suitable electrical insulation applications.
PEEK has good electrical insulating characteristics and high-temperature capability, making it useful for certain electrical and electronic components.
However, the term “insulation material” should be used carefully.
If a customer requires PEEK 30% GF specifically for electrical insulation, the material should be evaluated against the application’s requirements, including:
- Dielectric strength
- Volume resistivity
- Surface resistivity
- Dielectric constant
- Dissipation factor
- Operating temperature
- Frequency
- Environmental exposure
Therefore, PEEK 30% Glass Filled Sheet is better described as a high-performance engineering plastic with electrical insulation properties rather than simply an “insulation sheet.”

- Dimensional tolerances
After machining, components should be inspected according to the required dimensional specifications.
Why Choose PEEK 30% Glass Filled Sheets?
