Nylium Starline Aluminum-Reinforced Star-Profile Trimmer Line Ø 1.3 mm x 15 m Grey - Part Number: 45271399

The Nylium Starline star-profile grass trimmer line (part number 45271399, OEM reference 533744) is an aluminum-reinforced cutting monofilament engineered to provide exceptional cutting speed and anti-welding properties on corded electric lawn edgers and cordless battery trimmers. Formulated with a specialized nylon copolymer matrix embedded with aluminum particles, it features an ultra-fine 1.3 mm diameter with a distinct star-shaped (multi-edged) cross-section and a total length of 15 meters in a compact spool. The integrated aluminum powder delivers outstanding heat dissipation, preventing line fusing inside the spool under friction, while the sharp multi-point star edges provide a scissor-like shearing cut through tender lawn grass with minimal aerodynamic resistance and battery drain.

Key Features & Cutting Advantages

• Aluminum-Infused Nylon Copolymer: Metallic aluminum particles distributed throughout the polymer matrix conduct heat away from the spool core, virtually eliminating line welding and spool binding.
• Starline Multi-Edge Profile (Ø 1.3 mm): Five sharp cutting ridges slice clean through grass blades rather than whipping or shredding them, promoting rapid turf healing and eliminating brown, frayed leaf tips.
• Enhanced Abrasion Resistance: The composite polymer-aluminum structure delivers superior mechanical durability against concrete borders, masonry pavers, and chain-link fences.
• Low Aerodynamic Drag & Energy Savings: Fine 1.3 mm star gauge cuts cleanly through the air, easing the load on compact electric motors and significantly extending cordless battery runtime (18V/20V).
• Convenient 15-Meter Spool: Handy, lightweight roll length perfectly dimensioned for fast, hassle-free rewinding of manual spools and automatic bump-and-feed trimmer cassettes.

Technical Specifications

Application Areas & Head Compatibility

Application Parameter	Operational Guidance
Vegetation Types	Manicured lawn grass, garden borders, pathway edging, and neat trimming around delicate flowerbeds and planters
Trimmer Head Compatibility	Compact manual spools, auto-feed cartridges, and single/dual-line bump-feed cassettes for light trimmers
Hard Surface Performance	Outstanding anti-welding and wear performance when trimming alongside stone borders, paved curbs, and masonry

Usage & Storage Best Practices: Store the spool in a cool, shaded environment to protect the copolymer matrix from drying out and turning brittle; if the monofilament has been stored in dry conditions for an extended duration, submerge it in water for a few hours prior to rewinding to restore optimum flexibility. Always wear certified eye protection and closed footwear during trimming operations, and confirm that the machine safety guard remains firmly attached.
