ULTEM is one of the most widely used engineering plastics. It generally comes in two forms: plasticized and unplasticized ULTEM. Unplasticized ULTEM is used in rigid parts like pipes and fittings. CNC machining in ULTEM is generally done with this rigid version of the material. Plasticized ULTEM is used in applications that require flexibility like cables or small tubes. The production of ULTEM uses fewer nonrenewable raw materials by volume than most other plastics, making it one of the greenest plastics available. CNC machining in ULTEM is similar to that of other engineering plastics, and thanks to its rigidity and hardness, it machines relatively easily.
ULTEM material, or polyvinyl chloride, is an engineering plastic with excellent ultraviolet (UV) resistance, insulating properties, and resistance to moisture ingress. It is a popular choice for piping and construction materials, as well as for the electrical, energy, and medical industries. You can select ULTEM as a material for CNC machining in the FlagShip Instant Quoting Engine℠.
CNC PlasticsMachining ULTEM 1000 allows for a wide array of applications that take advantage of this material’s exceptional properties. Thanks to it's high strength and ability to operate at high temperatures; it is a great material for aerospace applications. It is also hydrophobic and stable when exposed to steam or boiling water, making it suitable for components in reusable medical devices. While generally resistant to a broad range of chemicals, care does need to be taken with certain types, such as strong bases and some halogenated solvents, which can attack the material. ULTEM 1000 is also known for it's exceptional dielectric strength, making it one of the best options for demanding electrical applications.
