Material Notes:
Parts created with Somos® BioClear are designed for medical applications that are non-implant and have limited contact with the body such as device prototyping. They are shatter-resistant so they won’t break during shipping, accidental dropping, or during a surgical procedure. The parameters for medical testing are limited. It remains the responsibility of the device manufacturer to determine the usage fit for each particular device. This product is ISO 10993-5, ISO 10993-10, USP Class VI certified.
