Reliance PPCP Repol D120MA

Reliance Repol D120MA is a polypropylene impact copolymer (PPCP) grade developed for injection moulding applications where high impact strength and antistatic performance are critical. Engineered with a built-in antistatic agent, D120MA reduces static charge buildup, making it ideal for automotive interiors, luggage shells, industrial housings, and compounding bases where dust, lint, or static-related defects must be minimized. Its medium-high flow (MFI 12) enables reliable moulding of complex, medium/thick-wall parts without sacrificing toughness—delivering robust, durable products for demanding environments.

Technical specifications

Applications & use cases

Automotive components

D120MA is engineered for automotive bumpers, interior trims, battery boxes, and underbody shields. Its high notched impact strength (550 J/m) ensures drop resistance and durability, while the antistatic agent minimizes dust attraction and static-related defects—critical for painted or electroplated parts and assembly environments.

Luggage shells

For hard-shell suitcases, trolley frames, and travel goods, D120MA’s toughness delivers long-lasting, crack-resistant products that withstand rough handling. The antistatic property keeps luggage surfaces cleaner and reduces lint pickup during storage and transport.

Compounding base resin

D120MA is an ideal matrix for talc- or glass-filled automotive compounds, TPE blends, and weatherable formulations. Its antistatic feature reduces dust during handling and processing, and its high impact strength survives compounding shear, supporting demanding technical applications.

Processing guidelines

• Melt temperature: 200–260°C
• Mould temperature: 15–50°C
• Injection speed: High speeds leverage antistatic flow; ensure proper packing to avoid sink marks in ribs and bosses
• Antistatic benefit: Reduces mould release issues and static-related defects in cleanroom or dust-sensitive production
• Troubleshooting:
  • Flow marks: Increase injection speed
  • Warpage: Use balanced cooling
  • Short shots: Optimise gate size and melt temperature

Performance advantages

• Antistatic edge: Built-in antistatic agent reduces static charge, dust pickup, and static-related defects—outperforming standard PPCP grades in automotive, luggage, and industrial settings.
• Superior impact: 550 J/m notched Izod impact provides drop and crack resistance in demanding applications.
• Balanced flow: MFI 12 delivers processability for medium/thick-wall parts, unlike ultra-high MFI grades that may lose toughness.
• Regulatory breadth: Complies with major global and Indian food, pharma, and consumer goods standards.
• Versatile compounding: Excellent base for filled and blended technical compounds.
