PTFE coating for use in the medical field, where health care is by nature the primary objective for professional clinicians, has the opportunity to enhance product performance together with medical performance. Improvements with medical and pharmaceutical devices that are PTFE coated contribute to the engineering design of the product. There are many medical applications that can benefit from PTFE coatings, these range from analytical and surgical instrumentation, autoclave and sterilisation equipment and packaging for pharmaceutical products.
The functions of PTFE coatings help meet design and manufacturing control requirements alongside the advanced materials, coupled with quality assurance measures benefitting the end user. Some PTFE coatings have been available for many years, resulting in well tried and tested applications culminating in device performance. PTFE, a degradation resistant polymer, for use with such applications as implantable medical devices have relied on these properties, in particular for lubricious purposes. It must be recognised that not all applications benefit from PTFE coatings, it is most advisable to read the policy document issued by, Chemours Policy Regarding Medical Applications of Chemours Materials (January 1, 2011). PTFE coatings have been successful with implantable devices such urinary, orthopaedic and respiratory devices, for the provision of low friction and to ease the insertion into bodily tissue.
PTFE coatings for medical applications rely upon an even coating over the complete surface and a surface that can be complex in geometry. Achieving a coat thickness that is consistent depends upon skill and expertise, together with the appropriate coating material, ensures that product quality in maintained throughout the production.
