PP is particularly resistant to impact and bending, as well as to many chemicals (e.g., acids, alkalis, solvents).
The disadvantage of polypropylene is that it is difficult to achieve adhesion to the print bed and it has a high tendency to warp, so the use of a special printing surface or adhesive layer (e.g., PP tape, BuildTak PP Sheet, insulating tape) is recommended.
Where to use it:
- Chemical-resistant containers, covers
- Live hinges, bendable connectors
- Lightweight, flexible machine parts, prototypes
- Food industry components (PP raw material is often food-safe)
Where not to use it:
- In environments with high heat loads (melting point approx. 100–110 °C)
- Where extreme dimensional accuracy or rigidity is required
Advantages of FilamentOn PP:
- Very good chemical resistance
- Flexible, impact-resistant
- Lightweight – low-density material (approx. 0.9 g/cm³)
- May be suitable for contact with food
- Developed and manufactured in Hungary
