Product Description
YONEI Engineered Color Masterbatches
Precision Color. Engineered Performance. Zero Compromise.In modern high-performance manufacturing, color is never just visual - it's functional integrity, brand trust, and regulatory assurance in one pellet. At YONEI Innovations, we move far beyond commodity tinting. Our YONEI™ portfolio delivers fully engineered, application-specific color masterbatches, co-formulated with performance additives and optimized for demanding engineering thermoplastics.

2,Globally compliant: RoHS, REACH, FDA, UL 94, EN 45545-2, FAR 25.853
3,Rapid support: Lab-matched samples in ≤5 working days
Why YONEI™ Stands Apart
| Advantage | Technical Impact | Real-World Benefit |
| Nano-Dispersion TechnologyParticle size < 0.8 µm (verified by SEM) | Eliminates specks, streaks & haze; achieves Level 1-2 dispersion (ISO 18553) | Perfect surface finish on thin-walled automotive trim, LED lenses, and consumer electronics housings |
| High-Temp StabilityTested up to 320ºC, validated per ISO 105-A02 (30 min @ max processing temp) | ΔE < 1.0 after thermal aging - no fading, blooming, or pigment degradation | Reliable color consistency in PC, PA66, and PBT injection molding - even under repeated regrind cycles |
| Functional Integration ("Color+")Co-dispersed UV stabilizers, flame retardants (halogen-free), anti-static agents, or anti-scratch additives | Single-pellet solution replaces multiple additive masterbatches | Reduces handling steps, improves batch repeatability, and eliminates compatibility risks |
| Resin-Specific Carrier DesignNot "one-size-fits-all": each series uses a chemically matched carrier resin | Zero interfacial stress, no impact on base polymer's tensile strength, impact, or ductility | Maintains full mechanical performance - critical for structural automotive or EV battery components |
