产品详细信息

聚甲醛GF25%塑料树脂

特点：聚甲醛原材料，一种合成树脂，也称聚甲醛树脂、聚甲醛塑料、钢材等。；它是一种白色或黑色的塑料颗粒，具有高硬度、高硬度和高耐磨性。主要用于齿轮、轴承、汽车零部件、机床、仪表内件、玩具等起骨架作用的产品。它是一种高度结晶的聚合物，表面光滑、有光泽、吸水率小、尺寸稳定性、耐磨性（非常优异的摩擦性能）、高强度、良好的自润滑性（良好的滑动性能）、良好的着色性、表面高硬度、良好的刚性、高抗疲劳性、良好的尺寸稳定性、高尺寸精度，耐油性和耐过氧化物性

POM具有高强度、刚性、良好的弹性和良好的耐磨性。其力学性能优良，比强度可达50.5MPa，比刚度可达2650MPa，与金属材料非常接近。POM的力学性能随温度变化不大，共聚POM的变化略大于均聚POM。POM的冲击强度较高，但常规冲击不如ABS和PC；POM对缺口非常敏感，缺口可使冲击强度降低90%。POM的疲劳强度非常突出。10次集中载荷后，疲劳强度可达35MPa，而PA和PC的疲劳强度仅为28MPa。POM的蠕变性能与PA相似，在20℃、21MPa和3000h时仅为2.3%，受温度影响较小。POM的摩擦系数小，耐磨性好（POM>PA66>PA6>ABS>HPVC>PS>PC），极限PV值大，自润滑性好。当POM产品相互研磨时，当施加高负载时，可能会产生类似尖叫声的噪音

POM具有良好的电气绝缘性，几乎不受温度和湿度的影响；介电常数和介电损耗在较宽的温度、湿度和频率范围内变化不大；优异的耐电弧性能，可在高温下使用。POM的介电强度与厚度有关，厚度为0.127mm时为82.7kV/mm，厚度为1.88mm时为23.6kV/mm

Product Details

POM GF25% Plastic Resin

Features: POM raw material, a kind of synthetic resin, also known as polyoxymethylene resin, POM plastic, steel material, etc.; it is a white or black plastic particle with high hardness, high rigidity and high wear resistance. Mainly used for gears, bearings, auto parts, machine tools, instrument internals, toys and other products that play a role as skeletons. It is a highly crystalline polymer with smooth, shiny surface, small water absorption, dimensional stability, wear resistance (very excellent friction properties), high strength, good self-lubrication (good sliding properties), good colorability, surface High hardness, good rigidity, high fatigue resistance, good dimensional stability, high dimensional accuracy, oil resistance and peroxide resistance.

POM has high strength, rigidity, good elasticity, and good 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 little 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 that of ABS and PC; POM is sensitive to notches, and the notches can reduce the impact strength by as much as 90%. The fatigue strength of POM is very outstanding. After 10 focal load, the fatigue strength can reach 35MPa, while that of PA and PC is only 28MPa. The creep property of POM is similar to that of PA, only 2.3% at 20℃, 21MPa, and 3000h, and it is little affected by temperature. The friction coefficient of POM is small, the wear resistance is good (POM>PA66>PA6>ABS>HPVC>PS>PC), the limit PV value is large, and the self-lubrication is good. When POM products are ground against each other, a squeal-like noise is likely to be generated when a high load is applied.

POM has good electrical insulation and is hardly affected by temperature and humidity; dielectric constant and dielectric loss vary little over a wide range of temperature, humidity and frequency; excellent arc resistance, and can be used at high temperatures Keep. The dielectric strength of POM is related to thickness, 82.7kV/mm when the thickness is 0.127mm, and 23.6kV/mm when the thickness is 1.88mm.
