Abstract

A polyoxymethylene composition includes a polyoxymethylene copolymer with 1,3-dioxolane as a comonomer, a wear resistance agent, a nucleating agent, and an antistatic agent. A ramp is made of the polyoxymethylene composition. The ramp and the polyoxymethylene have excellent low-wear-debris property. The low wear debris polyoxymethylene composition can be used to produce a ramp for many different designs of hard disks, such as PMR (perpendicular recording)+TDMR (Two-Dimensional Magnetic Recording), SMR (Shingled Magnetic Recording), HAMR(HAMR (Heat Assisted Magnetic Recording)+SMR+TDMR), BPMR(BPMR (Bit Pattern Media Recording)+SMR+TDMR), and helium-filled hard disk.
