Bad - adhesion issues, thin walls,
Good - pp jokes, semi flexible, not hygroscopic
Are there any technical / mechanical capabilities (outside of its flexibility to produce sturdy springs and such) of PP that only it can provide over other, less environmentally damaging materials?
I’m always trying to stick with materials that are either compostable (PHA) or truly recyclable (PLA, PETG) unless there are properties I absolutely need (like ASA for UV resistance & strength or TPU for flexible & protective parts). I wonder what PP does over TPU or other more common filaments and how it compares in terms of sustainability.
PP has exceptional chemical resistance that other filaments don’t - it’s basically immune to most acids, bases, and solvents which makes it perfect for lab equipment or chemical containers where PLA or PETG would just dissolve.
