In the medical and diagnostic sector<\/strong>, the demand for radiopaque, non-toxic, and processable<\/strong> materials is constantly growing.
\nX-ray shielding thermoplastic compounds<\/strong>, such as those from the LATIGRAY<\/strong> family, offer a concrete response to the needs for radiological traceability, biocompatibility, and sustainability<\/strong> required by modern medical equipment.<\/p>\n

Radiopacity and Non-Toxicity: Key Requirements in Medical Devices<\/h2>\n

Implantable or diagnostic devices<\/strong> that need to be visible to X-rays \u2014 such as catheters, markers, surgical clips, or endoscopic instruments \u2014 require materials with high density and radiographic contrast<\/strong>.
\nTraditionally, this function was entrusted to heavy metals such as lead<\/strong>, which are increasingly excluded today due to toxicity and disposal difficulties.<\/p>\n

Tungsten-based radiopaque compounds<\/strong> therefore represent an innovative and safe solution<\/strong>, capable of ensuring X-ray visibility<\/strong> without compromising the material’s biocompatibility<\/strong>.<\/p>\n

LATIGRAY 82-03 CW\/96: PA12-based Radiopaque Compound<\/h2>\n

Among the most advanced materials in the sector, LATIGRAY 82-03 CW\/96<\/strong> stands out, an X-ray shielding thermoplastic compound<\/strong> developed by LATI for medical and diagnostic applications.
\nIts PA12-based formulation<\/strong> combines a flexible and chemically inert thermoplastic matrix<\/strong> with a load of over 90% by weight of tungsten<\/strong>, ensuring excellent radiological shielding<\/strong> and certified non-toxicity<\/strong>. <\/p>\n

Certified Non-Toxicity According to ISO 10993-5<\/h3>\n

LATIGRAY 82-03 CW\/96 Natural 0193F3<\/strong> has successfully passed the cytotoxicity tests<\/strong> required by the ISO 10993-5<\/strong> standard, demonstrating absence of cellular reactivity<\/strong> and suitability for transient contact with biological tissues<\/strong>.
\nThis result qualifies it as a non-cytotoxic material<\/strong>, suitable for the production of non-permanently implantable medical components<\/strong>.<\/p>\n\n\n\n\n\n\n\n\n\n
