Grade-by-grade notes and applications across PP, PA, PC, ABS, PC/ABS and PPS.
PA6 GF30 Versus GF50: When Should You Step Up to GF50?
GF50 adds about 60% stiffness but loses flow, worsens fibre show and doubles tool wear — worth it only in specific cases.

How Is UL94 5VA Achieved on PC/ABS? Wall Thickness and the Yellow Card System Explained
V-0, V-2, 5VA and 5VB are not the same axis. Change wall thickness, colour or batch and the yellow card finding has to be re-established.
