Almost Unbreakable!: PolyMax PETG is an advanced PETG filament with enhanced toughness, ductility, and durability, making it ideal for applications requiring high impact resistance. Its mechanical properties are comparable to ABS, and it combines excellent strength with great printability. Tangle-Free & Moisture-Free: PolyMax PETG filament is carefully wound to prevent tangling, dried, and vacuum sealed with desiccant in a resealable ziplock bag. Always hold the filament tip to avoid nodes, and use the holes on the spool to help prevent this issue.
