High Gloss Polycarbonate (PC)
Premium Surface Finish PC for Aesthetic & Functional Components
High Gloss PC is specifically formulated for applications where appearance quality is as important as mechanical performance. Through optimized molecular structure and melt flow control, this material achieves a smooth, mirror-like surface directly from injection molding, eliminating the need for painting or polishing.
Compared with standard PC, high gloss grades provide better surface leveling, reduced flow marks, and enhanced visual consistency, making them ideal for visible parts.
Material Design & High-Gloss Surface Mechanism
High Gloss PC utilizes a carefully balanced resin architecture and additive system to improve surface replication during molding.
