770GL30H Glass Fiber Reinforced(GF) PEEK

Features of 770GL30H Glass Fiber Reinforced(GF) PEEK

• Tensile Strength: ~165-170 MPa (vs. ~90-100 MPa for pure PEEK), ensuring structural integrity under high loads.

• Flexural Modulus: ~11,000 MPa, providing stiffness for precision components.

• Impact Resistance: Balanced performance with Charpy notched impact strength (~9 kJ/m²) and unnotched impact strength (~50-55 kJ/m²), resisting fracture in dynamic environments.

Superior Thermal Stability 770GL30H retains PEEK’s exceptional heat resistance with:

• Glass Transition Temperature (Tg): 143℃ (consistent with pure PEEK), indicating its semi-crystalline structure.

• Heat Deflection Temperature (HDT): Up to 315-328℃ (at 1.8 MPa), enabling use in high-temperature applications (e.g., engine compartments).

• Long-Term Use Temperature: 260℃ (UL 946B), maintaining mechanical properties over extended periods in harsh conditions.

Dimensional Stability The low linear thermal expansion coefficient of 770GL30H (comparable to metal aluminum) reduces warping and deformation during processing or operation. This makes it ideal for precision parts like semiconductor wafer carriers or medical implants, where tight tolerances are critical.

Chemical and Environmental Resistance 770GL30H inherits PEEK’s resistance to most chemicals (except concentrated sulfuric acid) and exhibits low water absorption (~0.04-0.3% after 24 hours). It also retains flame retardancy without additional additives, meeting UL94 V-0 standards (1.5mm thickness) and producing minimal smoke—key for aerospace and electronics safety. 5. Processing Characteristics As an injection-grade material, 770GL30H is designed for ease of molding:

• Melt Flow Rate (MFR): 5 g/10min (at 380℃, 5.0kg), balancing flowability for complex geometries with structural integrity.

• Shrinkage Rate: Low and controlled (MD: 0.8%, TD: 0.3%), minimizing dimensional deviations in molded parts.
