OPaL PPCP Opalene EI01N
Opalene EI01N is a nucleated, high-melt-strength polypropylene impact copolymer (PPCP) produced by ONGC Petro additions Ltd (OPaL) using advanced INEOS gas-phase technology. Engineered for extrusion and blow-moulding, EI01N delivers a unique balance of rigidity, impact strength, and melt strength—making it ideal for corrugated/twin-wall sheets, pipes, thermoformed trays, and blow-moulded containers. The grade is optimized for converters seeking high performance, dimensional stability, and process consistency.
Deep Technical Insights
Opalene EI01N’s heterophasic block copolymer structure, created via INEOS gas-phase polymerization, features a semi-crystalline PP matrix and a finely dispersed rubber phase. This architecture delivers high melt strength for stable extrusion and blow-moulding, while maintaining robust impact resistance and flexural modulus. Nucleation accelerates crystallization, reduces cycle times, and improves dimensional stability—crucial for multi-cavity extrusion lines and complex profiles. The grade’s low moisture absorption, stain resistance, and solvent resistance ensure reliable performance in industrial, agricultural, and packaging environments.
Applications & Industry Use Cases
Corrugated / Twin-Wall Sheets: EI01N is ideal for PP hollow boards used in industrial packaging, logistics, signage, and construction. Its high melt strength supports stable sheet extrusion, while impact resistance protects against drops and stacking loads.
Corrugated Pipes & Fittings: The grade’s stiffness and toughness enable durable pipes and fittings for drainage, cable ducts, and water management, withstanding burial, installation, and mechanical stress.
Thermoformed Products & Blow-Moulded Containers: EI01N excels in rigid trays, industrial bottles, and containers formed by thermoforming or blow-moulding, offering lightweight designs with strong impact and stacking performance.
Performance Advantages of Opalene EI01N PPCP
Opalene EI01N delivers superior melt strength for extrusion and blow-moulding, ensuring stable parison and sheet behaviour. Its impact resistance (150 J/m Izod) and flexural modulus (1,100 MPa) support load-bearing, stackable products. The grade’s nucleation reduces cycle times and warpage, while its chemical and stain resistance, low moisture uptake, and recyclability make it a sustainable, high-performance choice for converters and OEMs.
