Paraformaldehyde UV resistant POM polymer

Anti-ultraviolet POM is a POM material with anti-ultraviolet effect for outdoor applications. Compared with ordinary POM, this material has a significantly improved outdoor application life and ensures the stability of various properties of the material.

Mechanical properties POM has high strength and rigidity, good elasticity, good wear resistance and wear resistance. Its mechanical properties are excellent, the specific strength can reach 50.5MPa, and the specific stiffness can reach 2650MPa, which is very close to metal. The mechanical properties of POM change slightly 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 not as good as ABS and PC; POM is sensitive to the gap, and the impact strength can be reduced by as much as 90% if there is a gap. The fatigue strength of POM is very prominent. After 10 alternating loads, the fatigue strength can reach 35MPa, while PA and PC are only 28MPa. The creep property of POM is similar to that of PA, it is only 2.3% at 20, 21MPa, and 3000h, and it is little affected by temperature. POM has a small friction factor, good wear resistance, a large limit PV value, and good self-lubrication. When POM products are rubbed against each other, it is easy to produce squealing noise under high load.

The anti-ultraviolet POM material has ultra-high rigidity, and it also has good elastic self-recovery ability. Such excellent characteristics, coupled with good creep resistance and fatigue resistance, these many excellent properties make POM aggregate Formaldehyde plastic materials are widely used in various fields as spring plastic materials. POM plastics provide the characteristics of lightweight automobiles, which reduces fuel consumption, and the carbon footprint of plastics is lower than that of metals, so the use of plastic materials can reduce greenhouse gas emissions; plastics provide easy processing characteristics, making automobile manufacturing costs It can also make the interior or exterior design of the car more fashionable. With the support of the above factors, plastics will continue to play an important role in the development of automobiles.
