Selection & Differentiation
When to choose PA-749K
Choose PA-749K when PA-747's impact is not enough; accept lower gloss and rigidity as the trade-off.
Selection advice
PA-749K vs PA-747: more impact, less gloss/rigidity. vs PA-709: PA-749K is injection super-impact; PA-709 adds the lowest-temp performance.
