HMEL PPCP Polysure CM25NR
HMEL Polysure CM25NR is a nucleated heterophasic polypropylene impact copolymer (PPCP) reactor grade, engineered via Spheripol-II technology by HPCL-Mittal Energy Ltd. With a melt flow index of 25 g/10 min, CM25NR is optimized for injection moulding and compounding applications that demand dimensional stability, process efficiency, and excellent stiffness-impact balance. Nucleation accelerates crystallisation, reduces cooling time and energy consumption, and minimizes warpage—making CM25NR the material of choice for rigid packaging, automotive parts, and masterbatch compounding. Supplied as natural granules in 25 kg PP bags, CM25NR is compliant with IS 10910 for food, pharma, and drinking water contact, and is PWM Rules 2016 compliant (non-SUP).
Functional Features
Polysure CM25NR stands out for its reactor-grade consistency, nucleated crystallisation, and balanced mechanical properties. Its moderate-high flow supports efficient mould filling, while high stiffness and good impact resistance enable the production of rigid, durable parts. The grade’s food-contact compliance and process reliability make it a trusted solution for converters, compounders, and OEMs.
Detailed Technical Specifications (Typical Values)
- Melt Flow Index: 25 g/10 min (ASTM D1238)
- Tensile Strength at Yield: 30 MPa (ASTM D638)
- Tensile Elongation at Yield: 6% (ASTM D638)
- Flexural Modulus (1% secant): 1500 MPa (ASTM D790A)
- Notched Izod Impact (23°C): 80 J/m (ASTM D256A)
- Vicat Softening Point (10N): 152°C (ASTM D1525)

Processing Recommendations:
Melt temperature: 190–240°C; mould: 20–50°C. Low warpage with proper cooling and balanced pressures.
Applications & Industry Use Cases
Rigid Packaging
CM25NR is ideal for crates, pails, and rigid containers where high stiffness, dimensional stability, and warpage resistance are critical. Its nucleated structure supports precise, stackable, and durable packaging solutions.
Automotive Components
Automotive OEMs and compounders use CM25NR for interior and exterior parts requiring a balance of impact strength and stiffness. The grade’s reactor-grade uniformity and moderate flow enable efficient production of complex, robust components.
Compounding & Masterbatch
CM25NR serves as a reliable base resin for mineral-filled and colour masterbatch compounding. Its processability and nucleated morphology ensure efficient dispersion and consistent mechanical properties in custom PPCP blends.
Performance Advantages
Compared to non-nucleated or higher-MFI PPCP, CM25NR delivers lower warpage, faster cycles, and superior dimensional accuracy for mid-wall and rigid parts. Its Spheripol-II reactor technology ensures batch consistency, while nucleation provides energy and productivity gains. CM25NR is especially competitive for rigid packaging, automotive, and compounding uses, and is an alternative to higher-MFI grades like Reliance Repol B400MN, IOCL Propel 3400MN, and Haldia M340.
Compliance, Packaging & Storage
Food Contact Compliance:
Certified to IS 10910 for food, pharma, and drinking water contact; converter must validate final article compliance.
Packaging:
Natural granules in 25 kg PP bags.
Storage Guidelines:
Store dry, below 50°C, and away from direct sunlight.
