PPTD20 vs PPTD30 Differences
PPTD20 has 20% talc, PPTD30 has 30% talc. Higher filler = higher rigidity but lower impact. PPTD20 density 1.04-1.06 g/cm³, PPTD30 ~1.08-1.12 g/cm³.
PA6 Warpage Solutions
Main causes: uneven fiber orientation, uneven mold temp, anisotropic shrinkage. Solutions: higher mold temp, optimized gate location, longer hold time.
