Role & responsibilities :

1. Colour Development & Formulation
- Develop new colour formulations and matches per customer specifications (swatch, Pantone, or digital reference)
for all base polymer grades.
- Conduct trial batches on twin-screw extruders or internal mixers to achieve target colour for each base resin type.

2. Colour Matching & Consistency
- Use spectrophotometers (CIE L*a*b*, E matching) to ensure batch-to-batch colour consistency across all polymer families.
- Perform visual matching under standard light booth conditions.
- Document colour recipes, pigment loading levels, and processing parameters by base resin type.

3. Production Support
- Set up, monitor, and operate twin-screw extruders / internal mixers for colour compounding trials on multiple base resins.
- Manage raw material handling pre-colouring, drying, blending of masterbatch with base polymer grades.




- Execute production runs maintaining tight process control (temperature, screw RPM, feed rate, residence time).

4. Troubleshooting & Process Optimisation
- Identify and resolve colour mismatches, dispersion issues, and heat-stability problems (e.g., yellowing) across different polymer chemistries.
- Troubleshoot extrusion defects such as streaks, poor dispersion, or inconsistent output for every resin family.

5. Documentation & Reporting
- Generate daily/weekly quality reports for shift handover.
- Maintain Maintain batch records, colour recipe logs, and equipment maintenance logs by resin grade.

6. Lab & Plant Housekeeping
- - Maintain a clean, protected, and compliant working environment; adhere to safety protocols and PPE requirements.
