L85116MA Black Modified PMMA

Time:2026-02-25     Views:5     Source:PRIME UNION PLASTIC

Engineered for Two-Shot Automotive Lighting Bezels

Product Overview

L85116MA is a pre-colored black modified PMMA material in pellet form, specifically formulated for the injection molding of automotive lighting components. It is designed to meet the surface quality and dimensional stability requirements of tail light black bezels, headlight trim rings, and decorative frames produced via two-shot molding processes.

Key Features & Benefits

  • Consistent Jet-Black Color: Pre-colored pellets eliminate masterbatch-related variability, ensuring uniform gloss and deep blackness across production runs.

  • Two-Shot Molding Optimized: Rheology tailored for reliable bonding with clear polycarbonate or PMMA substrates during sequential molding.

  • Stable Processing: Melt flow rate of 2.2 g/10min (230°C/3.8kg) supports filling of thin-walled, complex geometries with reduced internal stress.

  • Proven Performance: Balanced mechanical properties for automotive interior and exterior lighting applications.

Application: Automotive Black Bezels

Modern tail lights and headlamps utilize black bezels to create contrast, mask internal components, and define the optical signature. L85116MA provides the necessary:
  • Heat Resistance: Suitable for LED-generating temperatures.

  • Dimensional Stability: Maintains fit and finish over service life.

  • Surface Quality: High-gloss, defect-free black appearance.


Application: Automotive Black Bezels
