Copolyamide Pellets For Hot Melt Filament Extrusion Virgin CoPA Granules For Hot Melt Yarn Production Virgin CoPA (Copolyamide) pellets are virgin-grade copolyamide raw material specially developed for hot melt filament extrusion and hot melt yarn spinning. Made from 100% virgin polymer without recycled contaminants, the granules feature stable melt flow, uniform particle size and low thermal degradation during long continuous spinning. After melt extrusion, it can produce
