WebJun 30, 2024 · The difference in hardness in the Delrin vs acetal comparison is not elaborate. Yet, it matters. Delrin has a hardness of 86 Shore D while POM copolymers have a hardness of 85 Shore D. Therefore, Delrin will be more resistant to impacts and abrasion. Also, it will have a lower coefficient of friction. WebThe coefficient of friction (µ) is a measure of the amount of friction existing between two surfaces. Noise Sliding interacting surfaces can create noise, which may not be desirable …
