PP (Polypropylene) is a semi-crystalline thermoplastic that is lightweight, with a density of approximately 1.05 g/cm³, making it one of the lightest materials available. Unlike other engineering plastics, PP combines excellent chemical resistance, high-temperature resistance, and fatigue resistance. It is known as the "hundred-fold plastic" for its outstanding performance under stress and repeated bending.
In 3D printing applications, PP is ideal for producing durable parts subject to frequent stress or repeated bending, food-grade containers, chemical accessories, and medical rehabilitation devices. It is the perfect material for thin-walled bending parts, snaps, and food container prototypes.
Density of approximately 1.05 g/cm³, one of the lightest engineering plastics, ideal for manufacturing lightweight products.
Non-toxic, odorless, and recyclable, meeting food-grade safety requirements.
Almost zero water absorption with good thermal stability, the lowest water absorption rate among the ten base materials.
Excellent resistance to acids, alkalis, salts, and oils, suitable for chemical and medical applications.
Excellent impact resistance, does not easily break under bending and tension.
Extremely resistant to a variety of chemicals.
Non-toxic, food-grade material, safe for food contact.
Low density (<1 g/cm³), ideal material for manufacturing lightweight products.
Good heat resistance, suitable for high-temperature applications.
Excellent electrical insulating material, suitable for electronic applications.
Printed products have a semi-transparent and smooth surface with excellent appearance.
