QTS PP Polypropylene Filament 1.75mm
The King of Chemical Resistance & Living Hinges
Solves what PLA and ABS can't. Extreme toughness (>200% elongation), ultra-lightweight (0.90 g/cm³ — floats on water), and FDA food-contact safe raw materials. Open-chamber friendly.
7 Reasons to Choose QTS PP Filament
□ Extreme Chemical Resistance
Highly resistant to acids, alkalis, solvents, and cleaning agents. Where PLA dissolves and ABS degrades, PP thrives. Perfect for lab equipment, chemical storage, and industrial containers.
□ Living Hinges That Never Break
With >200% elongation at break, QTS PP withstands thousands of bending cycles. The go-to material for snap-fit enclosures, living hinges, flexible clips, and springs.
⚡ Ultra-Lightweight — It Floats!
At 0.90 g/cm³, it is lighter than water and significantly lighter than PLA, ABS, and PETG. Ideal for drone frames, aquatic accessories, and any weight-sensitive application.
□️ FDA Food-Contact Safe
Manufactured with FDA food-contact compliant raw materials. Safe for direct food contact — print custom containers, cookie cutters, and kitchen accessories with confidence.
□ Low Warping, High Stability
QTS PP is specially formulated to minimize the notorious warping and poor bed adhesion typical of polypropylene. Excellent layer adhesion ensures strong, delamination-resistant prints.
□ Low Moisture Absorption
PP is naturally hydrophobic, making it far less sensitive to humidity than Nylon or PVA. Every spool is vacuum-sealed with desiccant for maximum shelf life.
□️ Open-Chamber Friendly
No heated enclosure required. Print on your Bambu Lab A1, Prusa MK4, Creality Ender 3, or any open-frame FDM printer. Just use a PP-compatible bed adhesive and you're good to go.

Frequently Asked Questions
Safety & Storage
- Ventilation: Print in a well-ventilated area. PP emits minimal fumes but good airflow is always recommended.
- Storage: Keep in original vacuum-sealed bag until use. Store with desiccant in a cool, dry location.
- Drying: If exposed to humidity, dry at 60°C for 2–4 hours in a filament dryer or oven before printing.
- Handling: Avoid prolonged skin contact with molten filament. Keep out of reach of children.
