Description
FC422 represents an advanced formulation within TPC’s Performance expandable polystyrene (EPS) product portfolio. This specialized grade consists of precisely engineered spherical polystyrene beads with integrated pentane expansion agent, designed specifically for applications requiring superior molding cycle efficiency and enhanced moisture resistance. Distinguished by its optimized small bead size morphology (0.5-0.7mm), FC422 delivers exceptional performance in thin-wall applications while maintaining excellent mechanical resilience. The material achieves industry-standard densities of approximately 25 kg/m³ while incorporating proprietary formulation elements that enhance both processing efficiency and end-product performance characteristics.
