PC GF15 (15% Glass Fiber Reinforced PC)
Balanced Structural Polycarbonate for Injection Molding Applications
PC GF15 is engineered for applications where standard PC lacks sufficient rigidity, but PC GF30 may be over-engineered. By reinforcing polycarbonate with 15% glass fiber, this grade delivers a balanced combination of stiffness, dimensional stability, and surface quality, making it suitable for both functional and semi-visible parts.
Compared with unfilled PC, PC GF15 significantly reduces deformation and creep. Compared with higher glass fiber grades, it offers better flowability and surface appearance.
Material Structure & Glass Fiber Reinforcement Design
PC GF15 uses controlled short glass fiber dispersion to create a reinforcing network within the polycarbonate matrix. This structure restricts polymer chain movement, increasing rigidity while preserving toughness.
