Centaur PP Medical Grade - Pellets

Centaur PP Medical is a high-performance medical graded polypropylene (PP) granulate specifically engineered for Large-Format Additive Manufacturing (LFAM). Our Centaur PP Medical pellets comply with the following ISO tests and U.S. Pharmacopeia (USP) guidelines for plastics:

• ISO 10993-4: test of hemocompatibility;
• ISO 10993-5 tests for in vitro cytotoxicity;
• ISO 10993-10 tests for irritation and skin sensitization;
• ISO 10993-11 tests for systemic toxicity;
• USP 661.1 guidelines for making pharmaceutical packaging systems;
• UPS Class VI classification for the biological reactivity of plastics and materials.

Next to complying to the abovementioned medical standard, Centaur PP Medical delivers exceptional layer adhesion, resulting in Z-strength values that rival injection-molded polypropylene. With an elongation at break of nearly 650%, Centaur PP Medical offers a unique combination of flexibility, toughness, and long-term durability. As a slightly soft and flexible polypropylene, Centaur PP Medical delivers superior impact resistance and reliable performance. Its heat resistance above 100 °C makes it a highly versatile material for demanding medical applications. 

Centaur PP Medical is the ideal choice for manufacturers seeking lightweight, impact-resistant and durable components in their medical applications.

Processing 

Pre-Drying: Not required 

Centaur PP Medical is a non-hygroscopic polymer and does not absorb moisture into its internal structure 

Storage and handling

Centaur PP Medical is considered an inert and safe material under standard storage conditions, presenting no significant hazards. To ensure maximum quality, stability, and long-term performance, proper storage practices are recommended.  

For best results:

• Store in a tightly sealed container to protect against moisture absorption.
• Keep in a dry, cool, and well-ventilated environment.
• Avoid direct exposure to sunlight or intense artificial light to preserve material integrity.
