- Raw Material & Additive QA: Oversee the testing and validation of critical raw materials including PVC resin, chlorine, stabilizers (Tin/Calcium-Zinc), lubricants, impact modifiers, and processing aids.

- Application & Performance Testing: Ensure comprehensive testing of CPVC compounds for critical properties such as inherent viscosity, chlorine content, thermal stability (Congo Red test), Fusion time (using Torque Rheometers), Izod impact strength, and Vicat Softening Temperature (VST).

- Regulatory & Certification Compliance: Drive and maintain product certifications required for CPVC applications, including NSF/ANSI 14 & 61, ASTM D2846, ASTM F441, and BIS (IS 15778)



standards. Coordinate with external auditors from certifying bodies.

- In-Process & Extrusion Validation: Partner closely with production to run extrusion trial lines, ensuring the compound exhibits optimal flow, gelation, and physical properties during pipe and fitting conversion.

- Root Cause Analysis & CAPA: Lead technical investigations into batch rejections, thermal degradation during processing, fish-eyes, contamination, or customer complaints. Deploy advanced Root Cause Analysis (RCA) to execute robust Corrective and Preventive Actions (CAPA).

- Management of Change (MOC): Evaluate and approve any changes in raw material vendors, compounding recipes, or process parameters to ensure there is no adverse impact on the long-term hydrostatic strength (LTHS) of the final product.

- Team Leadership & Lab Management: Manage and upscale the technical competencies of QA/QC chemists and lab technicians. Oversee the calibration and maintenance of specialized polymer testing equipment.

Preferred candidate profile

- Education:
- B.Tech / M.Tech in Chemical Engineering from a reputed institute.

- Experience: 10-15 years of experience in Quality Assurance/Control within a PVC/CPVC resin manufacturing / Chemical or advanced compounding plant. At least 45 years must be in a managerial position.

- Technical Skills:
- Expertise in chlorination techniques and equipment
- In-depth knowledge of CPVC compounding formulations, thermal stabilizers, and processing dynamics.
- Thorough familiarity with international piping standards (ASTM, NSF, ISO) and ISO 9001:2015 QMS.

- Soft Skills: Solid leadership presence, analytical mindset, uncompromising stance on quality benchmarks, and effective communication skills in English, Hindi, and Gujarati (preferred).
