Trivia

Delrin, a thermoplastic polyoxymethylene resin produced by the chemical company DuPont, has been used in a wide range of applications for decades. One of the most interesting facts about Delrin is that it has been used to make a wide range of unusual products, including prosthetic ears, horns for musical instruments, and even a pair of false teeth! In the summer of 2018, a woman in England was surprised to discover that her false teeth were made from Delrin after she was told that she needed to get her false teeth replaced. She had been wearing them for over five years without any issues, and discovered that many of the false teeth available on the market are made from Delrin for its durability and strength. This story highlights how versatile and reliable Delrin can be, and makes it an attractive choice for many applications. (Source)
