Reliance PPCP Repol AMI035N

Reliance Repol AMI035N is a polypropylene impact copolymer (PPCP) engineered for injection moulding applications demanding exceptional stiffness–impact balance, dimensional stability, and long-term durability. Produced using advanced process technology, AMI035N features a low melt flow index (3 g/10 min), making it the ideal PPCP for automotive components, crates, rigid packaging, furniture, and industrial mouldings where structural integrity and impact resistance are non-negotiable. The grade’s mechanical and thermal profile ensures performance in both moderate and demanding service environments.

Technical specifications

Flow & physical properties

• Melt Flow Index: 3 g/10 min (230°C/2.16 kg) – low-MFI for maximum toughness and rigidity
• Density: ~0.90 g/cm³ – standard for PP IC

Mechanical & thermal properties

• Tensile strength at yield: ~27 MPa – robust for automotive and structural parts
• Elongation at yield: ~8% – supports resilience under load
• Flexural modulus: ~1100 MPa – high stiffness for crates, furniture, and packaging
• Notched Izod impact (23°C): ~160 J/m – excellent impact strength for drop and stacking resistance
• Vicat softening point (10 N): ~150°C – resists deformation under moderate heat
• Heat deflection temperature (HDT, 0.455 MPa): ~90°C – suitable for automotive interiors and logistics

Regulatory compliance

• Conforms to IS 10910 (food/pharma/drinking water contact) and IS 16738:2018 (positive list)
• Additives and formulation meet FDA and global standards for safe packaging and consumer use

Deep technical insights

• Low-MFI advantage: AMI035N’s 3 g/10 min MFI is ideal for moderate-wall, high-strength parts, maximizing impact and stiffness while minimizing warpage and brittleness.
• Mechanical synergy: 1100 MPa flexural modulus and 160 J/m impact provide the stiffness and toughness required in automotive, crate, and furniture applications.
• Thermal reliability: Vicat 150°C and HDT 90°C ensure shape retention and performance in warm or sun-exposed environments.
• Dimensional consistency: Reactor-grade dispersion and process stability support repeatability for OEM and high-volume production.

Applications

Automotive components

AMI035N is engineered for interior trims, semi-structural parts, and components where both rigidity and impact resistance are essential. Its thermal and mechanical profile supports performance in cabin and non-critical under-hood service.

Crates & rigid packaging

High modulus and impact strength make AMI035N perfect for stackable crates, bins, and rigid packaging, supporting high stacking loads and repeated drops in logistics and warehousing.

Furniture

For chairs, tables, and modular furniture, AMI035N delivers the load-bearing stiffness and drop resistance required in institutional and consumer settings.

Industrial mouldings

The grade’s balance of strength and impact suits technical housings, machine guards, and industrial covers, providing ruggedness and dimensional stability for demanding uses.

Processing guidelines

• Barrel temperature: 190–230°C (mid-range 200–220°C for most parts)
• Mould temperature: 30–40°C (cooler for cycle time, warmer for finish and warpage control)
• Packing pressure/time: Essential for ribs and thick sections to prevent sink marks
• Injection tips: Use moderate injection speeds, ensure uniform wall thickness, and optimize gate/rib design for best results
