聚甲醛颗粒塑料原料

聚甲醛的本质是白色的。POM塑料是继尼龙之后发展起来的另一种优良树脂类型，具有优异的综合性能。聚甲醛具有优异的耐溶剂性、耐油性、弱酸性、弱碱性等功能。POM具有高硬度、高硬度、高抗蠕变和应力松弛能力、优异的耐磨性、自平滑性和抗疲劳性，POM学名为聚甲醛聚甲醛（简称POM）。无侧链、高密度、高结晶度的线性聚合物，具有优异的综合性能。POM的拉伸强度可达70MPa，在104℃下可长期使用，脆化温度为-40℃，吸水率小。然而，聚甲醛的热稳定性和耐候性较差，长时间暴露在大气中会老化。聚甲醛的机械性能相当好。它具有较高的强度和弹性模量，较小的摩擦系数和良好的耐磨性。POM还具有很高的抗蠕变和应力松弛能力。POM具有良好的尺寸稳定性和较低的吸水率，因此吸水率对其力学性能的影响可以忽略。聚甲醛具有良好的介电性能，在较宽的频率和温度范围内，其介电常数和介电损耗角正切变化很小。聚甲醛的耐热性较差，在成型温度下容易还原和结合醛。通常，在造粒过程中添加稳定剂。如果不受压力，聚甲醛可在140°C下短时间使用，长期使用温度为85°C。聚甲醛耐候性差，经大气老化后，其总体性能下降。然而，它的化学稳定性非常优越，尤其是对于有机溶剂，并且它的尺寸变化和机械性能非常小

Product Details

Pom Pellets Plastic Raw Materials

The essence of POM is white. POM plastic is another excellent resin type developed after nylon, and has excellent comprehensive functions. Polyoxymethylene has excellent solvent resistance, oil resistance, weak acid resistance, weak alkali resistance and other functions. POM has high hardness and rigidity, high creep resistance and stress relaxation ability, excellent wear resistance, self-smoothing, and fatigue-resistant POM scientific name is polyoxymethylene polyoxymethylene (POM for short). A linear polymer with no side chain, high density and high crystallinity, with excellent comprehensive functions. The tensile strength of POM can reach 70MPa, it can be used for a long time at 104℃, the embrittlement temperature is -40℃, and the water absorption is small. However, polyoxymethylene has poor thermal stability and poor weather resistance, and will age when exposed to the atmosphere for a long time. The mechanical properties of polyoxymethylene are quite good. It has high strength and elastic modulus, small friction coefficient and good wear resistance. POM is also highly resistant to creep and stress relaxation. POM has good dimensional stability and low water absorption, so the influence of water absorption on its mechanical properties can be ignored. Polyoxymethylene has good dielectric properties, and its dielectric constant and dielectric loss tangent change very little in a wide frequency and temperature range. The heat resistance of polyoxymethylene is poor, and it is easy to reduce and bind aldehyde at the molding temperature. Generally, a stabilizer is added during granulation. If it is not stressed, polyoxymethylene can be used at 140 °C for a short time, and its long-term use temperature is 85 °C. POM has poor weather resistance, and after atmospheric aging, its general performance has declined. However, its chemical stability is very superior, especially for organic solvents, and its size transformation and mechanical properties are very small.
