Introduction of PP

Polypropylene (abbreviated as PP) is a polymer made of propylene by addition polymerization, a semi-crystalline thermoplastic. PP materials are one of the most common plastics in the world, from electrical components to live hinges, due to their high toughness, chemical resistance and fatigue resistance. As shown in Fig. 1, even after 15 consecutive filament extrusions, the stabilized 3D printing PP composite revealed an unaltered morphology and the same tensile and impact strength as the initial material.

PP materials are widely used for prototyping and final products. CD BioSciences is a professional technology company engaged in 3D printing services, providing a variety of plastic 3D printing materials, including PP materials.

As a 3D printing material, 3D printing polypropylene requires extremely precise temperature management, and because of the characteristics of polypropylene itself and reasons related to 3D printing technology, compared with ABS and nylon materials, the 3D applications of PP materials are not so widespread. But PP materials are low-cost, recyclable and reusable, and retain their shape after bending or twisting without breaking, and usually do not cause sharp edges when broken. In addition, PP materials have excellent water resistance, translucent, high melting point, chemical resistance, insulation, tensile strength, elasticity and toughness, and are compatible with food and skin, which makes PP materials a very popular 3D printing material in a wide range of fields. PP can also be processed into composite materials to improve mechanical strength.

CD BioSciences provides high quality PP materials that have passed inspection criteria and are suitable for the 3D printing needs of a variety of industries, especially items that are light, waterproof or durable.
