Technical DataSheet | Supplied by AdvanSource Biomaterials

ChronoFlex AL™ 75D by AdvanSource Biomaterials is a strong, phthalate-free, aliphatic polycarbonate-based thermoplastic polyurethane (TPU + PC) elastomer. Is a bio-durable and biocompatible grade, available in antimicrobial, radiopaque and solution form. Exhibits low modulus of elasticity, inherent material strength and limited softening in-vivo. Offers excellent chemical-, solvent- and environmental stress-cracking resistance (ESCR). Designed to overcome surface degradation such as stress-induced microfissures. ChronoFlex AL™ 75D can be used across a broad range of areas ranging from oncology and neurology to cardiovascular disease management. Recommended for reliable performance in long and short term implantable devices. Complies with USP CLASS VI, ISO 10993-5, ISO 10993-11 and ISO 10993-10 regulations.
