Haldia PPCP Halene M325

Haldia Petrochemicals’ Halene-P M325 is a heterophasic polypropylene impact copolymer (PPCP) granule engineered for high-flow injection moulding. Manufactured using Spheripol technology, M325 delivers an MFI of 25 g/10 min, density of 0.90 g/cm³, and a well-balanced stiffness-impact profile. This makes it ideal for moulders and OEMs producing furniture, appliance housings, automotive trims, and as a base for compounding. M325 stands out for its processability, short cycle times, and glossy surface finish, giving you both productivity and premium aesthetics.

Technical specifications

Physical properties (MFI/density)

• Melt Flow Index: 25 g/10 min (230°C/2.16 kg) – enables fast fill and cycle reduction in thin-wall, multi-cavity moulds
• Density:90 g/cm³ – standard for PP IC, supporting lightweight, robust parts

Mechanical properties (stiffness/impact)

• Tensile Strength at Yield: 25 MPa – balanced strength for structural and load-bearing applications
• Tensile Elongation at Yield: 7% – offers flexibility and resistance to sudden shocks
• Flexural Modulus: 1150 MPa – provides structural stiffness for furniture and appliance parts
• Notched Izod Impact (23°C): 60 J/m – ensures toughness versus PP homopolymers, reducing breakage during handling

Thermal properties (Vicat/HDT)

• Vicat Softening Point (10 N): 140°C – suitable for moderately heated environments in appliances and interiors
• Heat Deflection Temperature (0.455 MPa): 84°C – handles typical automotive and white goods service temps
• DSC Melting Temp: 165°C – stable during high-speed injection cycles

Functional Features

Halene M325’s unique combination of flow, stiffness, and impact performance makes it a versatile and reliable choice for demanding injection moulding and compounding applications. Spheripol process ensures batch-to-batch consistency and high gloss.

Applications

Furniture and housewares

Halene M325 is widely used for chairs, tables, storage bins, and kitchenware. Its stiffness supports load-bearing, while impact resistance prevents breakage from drops. The glossy finish enhances product appearance for premium housewares.

Appliances and white goods

For fans, mixers, washing machines, and refrigerator parts, M325 offers the strength and thermal stability needed for housings, panels, and internal structures. Its processability reduces cycle times and improves surface quality.

Automotive components

M325 is suitable for non-critical interior trims, battery boxes, and under-hood covers. The grade’s impact-stiffness balance ensures durability against vibration and handling, while gloss adds aesthetic value to visible parts.

Compounding base

M325 serves as an excellent base resin for compounding and masterbatch production. Its high flow aids filler dispersion and smooth twin-screw extrusion, making it a preferred carrier for mineral, glass, or colour concentrates.

Processing guidelines

• Barrel temperature: 180–210°C
• Mould temperature: 30–40°C
• High-flow optimisation: Leverage 25 MFI for fast fill, short cycles, and thin-wall designs (1.5–2 mm possible in multi-cavity tools)
• Screw/mould design: Use standard PP IC compression ratio; ensure adequate packing to reduce sink marks in ribs and bosses
• Defect mitigation:
  • Warpage: Use balanced cooling
  • Flow marks: Increase injection speed
  • Short shots: Optimise gate design and location

Advantages vs competitors

Halene M325 matches or exceeds Reliance Repol B220MN/B250EG in flow and mechanicals, offering Indian moulders an edge in price, availability, and technical support. Spheripol process ensures superior gloss and batch consistency, while high MFI reduces cycle times and energy costs.
