Color streaks and color difference after TPE coloring; poor compatibility between the color masterbatch and the base material
Análisis de la causa
The TPE coloring carrier is selected by base material: PS carrier for SBS base, PP carrier for hard SEBS base, LDPE or EVA carrier for soft SEBS base; avoid PE carrier for overmolded parts affecting bonding
Solución
①Choose PS carrier for SBS base; ②Choose PP or LDPE carrier for SEBS base by hardness; ③Avoid PE carrier for overmolded parts; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Conclusión clave
The TPE coloring carrier is the knowledge of base material matching; wrong carrier selection causes color streaks and bonding problems together; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
