Medical Grade & Biocompatibility
HL-9960-xx-YL is developed for applications where biocompatibility and controlled material properties are important. Hailan provides relevant technical and quality documentation to support customer material evaluation and qualification.
For medical device applications, biocompatibility should not be assessed solely from the raw material name. The appropriate biological evaluation depends on the finished device, its materials, manufacturing process, intended use, body contact and duration of contact.
ISO 10993-1 provides the framework for biological evaluation of medical devices within a risk-management process. FDA also recognizes various ISO 10993 standards as consensus standards for medical-device biocompatibility evaluation.
Applications
Depending on the formulation and final-device qualification, HL-9960-xx-YL can be considered for molded silicone components used in areas such as:
Medical masks and respiratory components
Medical valves and sealing components
Negative pressure components
Medical device seals and gaskets
Healthcare equipment components
Transparent molded silicone parts
Other medical and healthcare products requiring liquid silicone rubber
