- Durability
- Abrasion resistance
- Temperature resistance
- Bonding/adhesion
- Conduct laboratory trials and material testing for new formulations.
- Identify and evaluate suitable raw materials, polymers, fillers, plasticizers, additives, pigments, and processing aids.
- Optimize formulations to achieve the required product specifications while maintaining target manufacturing cost.
- Conduct trials on production equipment and assist in scale-up from laboratory to commercial production.
- Troubleshoot formulation and processing-related problems during production.




- Study and improve the performance of existing TPR granules.
- Develop formulations for different grades, colours, hardness levels, and application requirements.
- Maintain detailed records of formulations, trials, test results, and modifications.
- Coordinate with the production, quality control, procurement, and product development teams.
- Establish and maintain specifications and testing parameters for incoming raw materials and finished TPR granules.
- Conduct comparative testing of competitor/reference materials and identify opportunities for improvement.
- Ensure consistency of granule quality from batch to batch.
- Assist in developing cost-effective and sustainable formulations.
- Stay updated on new TPR technologies, raw materials, additives, processing techniques, and industry developments.

Key Technical Skills
- Strong understanding of TPR/TPE materials and polymer technology.
- Knowledge of polymer compounding and extrusion processes.
- Understanding of formulation development and material compatibility.
- Knowledge of additives, fillers, plasticizers, pigments, and stabilizers used in TPR formulations.
- Ability to conduct and interpret material testing.
- Understanding of hardness, tensile strength, elongation, abrasion, flexibility, density,



and other relevant properties.
- Knowledge of extrusion, mixing, compounding, and granulation processes.
- Robust troubleshooting and analytical skills.
- Basic knowledge of quality-control procedures and documentation.
- Good understanding of production-scale trials and process optimization.

Desired Testing Knowledge Experience with or understanding of tests such as:
- Shore A hardness
- Tensile strength
- Elongation
- Abrasion resistance
- Tear strength
- Specific gravity / density
- Flexibility
- Compression set
- Slip resistance
- Heat and temperature resistance
- Adhesion/bonding performance
- Colour consistency
- Ageing and durability testing

Qualifications

Preferred:

- B.Tech / M.Tech in Polymer Technology, Plastics Technology, Rubber Technology, Chemical Engineering, Materials Science, or a related field.
- Diploma holders with strong practical experience in TPR/TPE compounding may also be considered.

Experience
- 1–5 years of relevant experience in TPR, TPE, rubber, polymer compounding, plastics, or related R&D.;
- Candidates with hands-on experience in TPR granule formulation and extrusion/compounding will be preferred.
- Freshers with strong academic knowledge and relevant laboratory/project experience may also be considered for a junior position.

Salary: As per experience and technical expertise. Note: Candidates with hands-on experience in TPR formulation, compounding, extrusion, and granule development will be given preference.

Pay: ₹80,000.00 - ₹100,000.00 per month
