PEEK 450GL30 is a medical-grade polymer composite consisting of polyetheretherketone (PEEK) reinforced with 30% by weight of glass fiber. The "temporal" designation refers to its primary application in temporal bone reconstruction—a critical area of cranial surgery requiring precise anatomical matching and long-term biocompatibility.
The "450" in the product name indicates the base PEEK resin grade, while "GL30" specifies the glass fiber content. This configuration is manufactured by leading suppliers such as Victrex and Invibio, both of which maintain ISO 10993 biocompatibility certification for implantable medical devices [2].

Why 30% Glass Fiber? This specific reinforcement level represents an industry-optimized balance between mechanical strength and processability. Lower glass content (10-20%) provides insufficient stiffness for load-bearing cranial applications, while higher content (40%+) can compromise injection molding flow characteristics and increase brittleness.
