Fluorosilicones are a family of elastomers that combine fuel and solvent resistance with low-temperature and high-temperature performance. During the 1950s, chemists at Dow Corning created fluorosilicone rubber (FSR, FVMQ) by modifying Silastic®, a dimethyl silicone, for sealing applications in the automotive and aerospace industries. The first fluorosilicones had modest mechanical properties, however, so many engineers began using FKM fluorocarbons instead.

Within the United States, a rubber compound intended for medical use must first meet FDA (Food & Drug Administration) requirements, which are defined in Title 21 CFR 177.2600 (Code of Federal Regulations). The FDA does NOT “approve” rubber compounds from the many companies that produce rubber seals. Rather, they provide a list of “Ingredients” that a rubber chemist can use when developing a rubber compound. The FDA has tested and evaluated these ingredients and have deemed them to be ‘safe’. Many rubber companies advertise that they have “FDA Approved Compounds”. Technically, this is not correct.
Whatever happened to 3D printing? When Tech Crunch asked that question back in the summer of 2016, many companies had already grown tired of hearing about the promise of additive manufacturing. Now, as another year winds down, there’s even less buzz about 3DP. Sure, GE is using additive manufacturing to make aircraft parts, but is there an application for 3D printing at your company in 2018?
