POM has high compressive strength, bending stiffness, goodductility, and good wear resistance. Its physical properties areexcellent, its strength reaches 50.5MPa, and its specific bendingstiffness reaches 2650MPa, which is very close to metal materials.The physical properties of POM change little with the temperature,and the change of mixed POM is slightly larger than that ofhomopolymer POM. 
POM has high impact and compressive strength, but its basicimpact is not as good as ABS and PC; POM is sensitive to notches,which can reduce the impact compressive strength by as much as 90%.The fatigue limit of POM is very prominent. After 10 alternatingload effects, the fatigue limit reaches 35MPa, while the fatiguelimit of PA and PC is only 28MPa.
The stress relaxation of POM is similar to that of PA, which isonly 2.3% at 20 ℃, 21MPa and 3000h, and is not affected bytemperature. POM has small friction factor, good wear resistance(POM>PA66>PA6>ABS>HPVC>PS>PC), high limit PVvalue and good self-adhesion. When the POM handicrafts are grinded,the high load effect is easy to cause the noise of similarscreaming.
