NuSil Technology has introduced a low-flow, high-consistency fluorosilicone grease for healthcare applications. MED-6731 is a silicone grease composed of a dimethyl methyltrifluoropropylsiloxane copolymer. It can be used in applications that require a solvent-resistant grease and may be used as a high-vacuum grease around glass, ceramic and ground glass joints. A fluorosilicone fluid may be used for applications in which dimethylpolysiloxane grease has compatibility issues with silicone rubber components; however, if migration is a concern, MED-6731 provides an excellent solution. A key to the lubricant is that, when it comes into contact, it won’t absorb into or swell the component. Cytotoxicity and trace metals testing are performed on each lot of MED-6731. A Master Access File and biological testing will be filed with the U.S. FDA.
