Customized Polyoxymethylene(POM) Clamp For Subsea Production Systems

Polytealdehyde POM material is the abbreviation of chemical name of polyoxy oxygenne. It is a high -crystalline polymer that has a smooth surface, shiny, stable water absorption, high wear resistance, high strength, good self -lubricating, good coloring, , Oil resistance and oxide。

The performance of this material is as follows: 

1. It has a very low friction coefficient and good geometric stability. It is especially suitable for making gears and bearing 2. It has high temperature resistance. Therefore, it is also used for pipeline devices (pipe valve, pump case), lawn equipment, etc. 3. It is a tough and elastic material. Even at low temperature, there is still good anti -creep characteristics, geometric stability, and impact resistance. 4. The commonly of polymer material has a good extension and anti -fatigue strength, but it is not easy to process. The co -vector materials have good thermal stability, chemical stability and easy processing. Regardless of the commonly of polymer materials or co -vector materials, it is crystalline materials and not easy to absorb water. 5. The degree of high crystallization leads to a considerable contraction rate, which can reach 2%~ 3.5%. There are different contraction rates for various enhanced materials. 6. Have good comprehensive performance. It is the hardest in thermoplastic plastic. It is one of the most intensive metal varieties in plastic materials. They are very good and can be used between -40 ° C-100 ° C for a long time. 7. It is a crystalline plastic with obvious melting point. Once the melting point is reached, the melt viscosity drops rapidly. When the temperature exceeds a certain limit or the melt heating time is too long, it will cause decomposition. Copper is a POM degradation catalyst. The part of contact with the POM melt should be avoided with copper or copper material. 8. According to the structure of the molecular chain, the formaldehyde can be divided into average formaldehyde and cluster formaldehyde. The former density, crystallization, and melting point are high, but the heat stability is poor, the processing temperature range is narrow (10 ° C), and the stability of the acid and alkali is slightly lower; It is not easy to decompose, and the processing temperature range is wide (50 ° C). The shortcomings of polydeons are that they are corroded by strong acids, poor weather resistance, poor adhesive, close to the temperature and softening temperature, and small oxygen limit index.
