Black white POM rods wear-resisting solid Plastic bars Polyoxymethylene rod stick Machining materials
POM has high strength and stiffness, good elasticity and good wear resistance. It has excellent mechanical properties, with specific strength up to 50.5mpa and specific stiffness up to 2650mpa, which is very close to metal. The mechanical properties of POM change little with temperature, and the change of copolymerized POM is slightly larger than that of homopolymerized POM. The impact strength of POM is higher, but the conventional impact is lower than that of ABS and PC; POM is sensitive to notch, and notch can reduce the impact strength by as much as 90%. The fatigue strength of POM is very prominent. After 10 alternating load, the fatigue strength can reach 35MPa, while that of PA and PC is only 28Mpa. The creep of POM is similar to that of PA, which is only 2.3% at 20 ¡É, 21MPa and 3000h, and is little affected by temperature. POM has small friction coefficient, good wear resistance (POM > PA66 > PA6 > ABS > HPVC > PS > PC), large limit PV value and good self lubrication. When POM products are grinded, it is easy to produce squeal like noise under high load.
