Engineering Plastics Masterbatch (SAN/PC/PA)
What is Engineering Plastics Masterbatch (SAN/PC/PA)?
A filler-free, high-purity carbon black masterbatch formulated for engineering resins at 25–40% CB content.
SAN, PC (polycarbonate), PA (nylon), ABS and POM carrier grades are engineered for electronics housings, automotive interior components, connectors and precision injection-molded parts requiring strict mechanical performance.
For polycarbonate and other clear engineering resins, we also produce tinted, smoked-grey and semi-transparent black grades — a see-through dark finish for display windows, light diffusers, instrument panels and electronic enclosures, with even color and high clarity.
Which applications is it best for?
| Application | Why this grade fits |
|---|---|
| Electronics housings (SAN/PC/ABS) | Filler-free, preserves mechanical properties |
| Automotive interior components | Matched carrier for engineering resins |
| Precision connectors & molded parts | High-purity dispersion for tight tolerances |
| Appliance structural parts | Stable color in PA, PC and POM |
