Role Purpose

The Polymer Formulation & Compounding Engineer is the technical engine of our product development and production operation. Working alongside our Process Engineer (twin-screw extrusion specialist), you will be responsible for developing, optimising, and validating masterbatch formulations across all three product lines, setting up and running our in-house formulation laboratory, and ensuring every product that leaves our plant meets customer specifications and regulatory requirements.

Job Description

1. Formulation Development

Develop new masterbatch formulation product lines from first principles
Select and evaluate raw materials — carrier resins (LDPE, LLDPE, PP, EVA), active additives, dispersing agents, and processing aids
Optimise additive loading levels, carrier resin compatibility, and let-down ratios for each product line
Apply Design of Experiments (DOE) methodology to formulation development for efficient, data-driven optimisation
Scale up formulations from lab scale to full production on the twin-screw compounding line
Develop and maintain a structured formulation database and technical documentation library

2. Twin-Screw Extruder — Compounding Operations

Work hands-on with our twin-screw extruder — setting process parameters including temperature profile, screw speed, feed rate, and torque
Define and optimise screw configuration for dispersive and distributive mixing of pigments and functional additives
Develop and document Standard Operating Procedures (SOPs) for all compounding operations
Troubleshoot process issues — melt degradation, poor dispersion, pellet quality defects — using structured root cause analysis
Monitor and control critical quality parameters during production runs

Education

Bachelor's Degree (minimum) in Polymer Engineering, Polymer Science, Chemical Engineering, or Materials Science
Master's Degree or higher in Polymer Engineering or Polymer Science is strongly preferred

Mandatory Technical Experience — You MUST have all of these

Minimum 5 years of hands-on experience in polymer compounding or masterbatch formulation in an industrial setting
Demonstrated hands-on experience operating a Twin-Screw Extruder (TSE) — setting temperature profiles, screw speed, torque monitoring, and feed rates
Direct experience in formulation development — not just quality testing but actually developing and optimising polymer formulations
Strong knowledge of polyolefin systems — LDPE, LLDPE, PP, EVA — as carrier resins
Proficiency in polymer characterisation techniques: MFI (Melt Flow Index), DSC, FTIR, density, and mechanical testing
Experience in lab-scale formulation trials and scale-up to production
Ability to read, develop, and work from P&ID drawings and process flow diagrams

Strongly Preferred Experience — Not mandatory but highly valued

Direct masterbatch manufacturing experience — colour MB, white MB, black MB, or functional/additive MB
Formulation knowledge in at least one of our three product lines: antimicrobial additives, antistatic agents, or UV/HALS stabiliser systems for agricultural film
Experience with Design of Experiments (DOE) for formulation optimisation
Familiarity with filter pressure value (FPV) testing for dispersion quality assessment
Experience setting up a polymer laboratory or developing SOPs in a new or growing facility
Technical service or R&D experience at an additive supplier (BASF, Clariant, Songwon, Evonik, Lanxess, or similar)
Knowledge of ISO 9001 quality management systems and internal auditing

Pay: RM6,000.00 - RM12,000.00 per month
