Delrin® 150, the middle ground between metal and plastic

Our Delrin® 150 is what’s known as an acetal class material. This means that it’s suitable to be used with lubricants and solvents, like gasoline, without any decline in performance. Often used in applications where exposure to wear and extreme moisture is guaranteed, it provides superior strength in areas where metal would be an unwise choice.

Custom cut Delrin parts

You can consider Delrin® the bridge between metal and plastic, offering a host of useful properties that many metals just can’t deliver. A unique fit for robotics, automotive, and in some cases aerospace applications, Delrin carries with it a high creep strength, meaning Delrin® can handle repeated loading without deformation. This makes it a great material for bushings and gears that need to be sturdy enough to withstand impacts, but also lightweight enough to fit project constraints.

Used in a variety of applications

In addition to being receptive to fastening applications, our custom cut Delrin® is also especially machinable, making it the go-to thermoplastic for parts that require tight tolerances and more intricate geometry.

Overall, our custom cut Delrin® parts are positioned for specialized applications that require properties of both plastics and metals to get the job done.
