POM性能特征
1。POM是一种乳白色不透明结晶线性热塑性树脂，具有良好的综合性能和着色性、高弹性模量、高硬度和硬度，其比强度和比刚度接近金属
2。优异的拉伸强度、弯曲强度、抗蠕变和抗疲劳性、抗反复冲击性，以及从载荷移除中获得的优异恢复性
3。摩擦系数小，耐磨性好，尺寸稳定性好，表面光泽好，粘弹性高，电绝缘性好，不受温度影响；绝缘电阻好，不受湿度影响
4。优异的耐化学性：除强酸、酚类和有机卤化物外，对其他化学品稳定，耐油；其力学性能受温度影响较小，热变形温度较高
5。缺点是阻燃性差，燃烧速度慢，氧指数小。即使添加了阻燃剂，也不能达到令人满意的要求。此外，耐候性不理想，户外应用应添加稳定剂
6。均聚甲醛具有较高的结晶度、机械强度、刚度，热变形温度优于共聚甲醛。共聚甲醛具有较低的熔点、热稳定性、耐化学性、流动特性和加工性能，优于均聚甲醛。新开发的产品包括超高流量（快速成型）、抗冲击和减少模具沉积等级，以及无机填充和增强等级
7。POM原材料吸水率大于0.2%，成型前应预干燥。POM的熔融温度与分解温度相近，可塑性较差。它可以注塑、挤出、吹塑、旋转模塑、焊接、粘接、涂膜、印刷、电镀、机加工，而注塑是最重要的加工方法。成型收缩率大，且模具温度应较高，或进行退火处理，或添加增强材料（如无碱玻璃纤维）

POM performance characteristics
1. POM is a milky white opaque crystalline linear thermoplastic resin with good overall performance and colorability, high elastic modulus, high rigidity and hardness, and its specific strength and specific rigidity are close to that of metal;
2. Excellent tensile strength, bending strength, creep resistance and fatigue resistance, resistance to repeated impacts, and excellent recovery from load removal;
3. Small friction coefficient, wear resistance, good dimensional stability, good surface gloss, high viscoelasticity, excellent electrical insulation, and not affected by temperature; good insulation resistance and not affected by humidity;
4. Excellent chemical resistance: In addition to strong acids, phenols and organic halides, it is stable to other chemicals and resistant to oil; its mechanical properties are less affected by temperature and have a high heat distortion temperature.
5. The disadvantage is that the flame retardancy is poor, it burns slowly in fire, and the oxygen index is small. Even if the flame retardant is added, the satisfactory requirements are not obtained. In addition, the weather resistance is not ideal, and the stabilizer should be added for outdoor applications.
6. Homopolyoxymethylene has high crystallinity, mechanical strength, rigidity, and heat distortion temperature are better than copolyoxymethylene. Copolyoxymethylene has a low melting point, thermal stability, chemical resistance, flow characteristics, and processability are better than homopolyoxymethylene. New The developed products are ultra-high flow (rapid prototyping), impact resistant and reduced mold deposition grades, and inorganic filling and enhanced grades.
7.The water absorption rate of POM raw materials is greater than 0.2%, and it should be pre-dried before molding. The melting temperature of POM is similar to the decomposition temperature, and the moldability is poor. It can be injection molded, extruded, blow molded, rotomolding, welding, bonding, film coating, Printing, electroplating, machining, and injection molding are the most important processing methods. The molding shrinkage rate is large, and the mold temperature should be higher, or annealing treatment, or adding reinforcement materials (such as alkali-free glass fiber).
