Polypropylene (often abbreviated as "PP") is one of the most widely used plastics on the planet. It's a favorite of engineers and manufacturers worldwide, covering a wide range of applications. With its toughness and exceptional fatigue resistance, it is the go-to material for creating functional prototypes and durable end-use parts. Since it has a low density, it can be used to create lightweight parts with a high strength-to-weight ratio.
Polypropylene also has excellent temperature, electrical, and chemical resistance. It can take temperatures up to 105°C, can be used as an electrical insulator, and can stand a wide range of bases and acids - including industrial cleaning agents. PP is also semi-flexible, translucent, and has low friction and smooth surfaces, making it suitable for producing everything from electrical components to living hinges.
Reasons to choose Ultimaker Polypropylene
Durable with high toughness and fatigue resistance (PP retains its shape after torsion, bending, and/or flexing)
Low friction and smooth surfaces
Good heat resistance (up to 105°C)
Chemical resistance to a wide range of bases and acids, including industrial cleaning agents
High electrical resistance makes it a good electrical insulator
Very resistant to moisture
Low density resulting in lightweight parts (high strength-to- weight ratio)
Excellent layer bonding
Adequate bed adhesion and low warping when using Advanced 3D Printing Kit adhesion sheets
Recyclable, for low environmental impact
