Medical PEEK white

TECAPEEK MT CLASSIXTM white is a high performance PEEK plastic developed for dental and medical technology applications. This material can have blood and tissue contact of up to 30 days and offers USP Class VI conformity on raw material. Further tests are run batch-to-batch according to ISO 10993-5 on stock shapes. Similar to other PEEK grades, this medical grade white PEEK demonstrates high resistance to hydrolysis even at high temperatures, very good sterilization capabilities, and outstanding chemical resistance. In some cases, prolonged contact duration of up to 180 days can be approved for certain dental applications.
