Prografen PETG Graphene Strong Filament JET BLACK 1.75mm 1kg

Description

Prografen PETG Graphene Strong Filament JET BLACK 1.75mm 1kg — High-strength graphene PETG for engineering and industrial 3D printing

Prografen PETG Graphene Strong Filament JET BLACK 1.75mm 1kg is a high-performance PETG-based 3D printing filament developed for engineering and industrial applications. Prografen PETG Graphene Strong Filament contains 5% edge-functionalized graphene flakes (EFG), which significantly improve the mechanical and functional properties of standard PETG. Compared with pure PETG, this material offers higher tensile strength, greater stiffness, improved wear resistance, better dimensional stability, and much higher flow rate, while still remaining easy to print and low in abrasion.

Key Benefits at a Glance

• 5% graphene reinforcement: Enhanced with edge-functionalized graphene flakes for stronger mechanical performance than standard PETG.
• Higher strength and stiffness: Offers 25% higher tensile strength and 20% higher stiffness than pure PETG.
• Very high flow rate: MFR is 170% higher than pure PETG, supporting faster printing while maintaining high print quality.
• Low abrasion: Can be printed with standard brass nozzles without excessive wear.
