Centaur PP is a high-performance polypropylene (PP) granulate, specially developed for large-format 3D printing (LFAM - Large Format Additive Manufacturing). This advanced material guarantees exceptional adhesion between layers, achieving Z-axis strength values comparable to injection-moulded polypropylene. With an elongation at break of almost 650%, Centaur PP offers a unique combination of flexibility, strength and durability. As a slightly soft and flexible polypropylene, Centaur PP provides excellent impact resistance and reliable performance. Its heat resistance of over 100°C makes it an extremely versatile material, suitable for demanding industrial and consumer applications. Thanks to its excellent printability, mechanical strength, chemical resistance and thermal stability, Centaur PP stands out as a high-quality polypropylene for LFAM 3D printing. It is the ideal choice for manufacturers looking for lightweight, impact-resistant and highly durable components across a wide range of industries.
