DuPont POM 900P DUPONT POM strength, high stiffness, good elasticity, anti-friction wear resistance. Excellent mechanical properties, strength up to 50.5MPa, specific stiffness up to 2650MPa, very close to the metal. Mechanical properties of POM small changes with temperature, co-POM POM than homo- change slightly larger. POM high impact strength, but the impact is less than conventional ABS and PC; POM notch sensitive, can drop as much as 90% of the notched impact strength. POM fatigue strength is very prominent, after 10 alternating loads, fatigue strength up to 35MPa, while the PA and PC only 28MPa. POM and creep resistance similar to PA at 20 ℃, 21MPa, was only 2.3% when 3000h, and little affected by temperature. POM's low coefficient of friction, wear resistance (POM> PA66> PA6> ABS> HPVC> PS> PC), the limit PV value is large, self-lubricating. POM products on time grinding, easy to produce a noise similar to scream at high loads.
