Product details

聚甲醛又名聚氧化次甲基，英文名polyxymethylene（简称POM）。分子结构规整和结晶性使其物理机械性能十分优异，有金属塑料之称。POM为乳色不透明结晶性线性热塑性树脂，具有良好的综合性能和着色性，具有较高的弹性模量，很高的刚性和硬度，比强度和比刚性接近于金属；拉伸强度，弯曲强度，耐蠕变性和耐疲劳性优异，耐反复冲击，去载回复性优；摩擦系数小，耐磨耗，尺寸稳定性好，表面光泽好，有较高的粘弹性，吹水性小，电绝缘性优，且不受温度影响；耐化学药品性优，除了强酸，故有吸振性、消音性；吸水性小，耐绝缘性好且不受湿度影响；耐化学药品性优：除了强酸、酚类和有机卤化物外，对其他化学品稳定，耐油；机械性能受温度影响小，具有较高的热变形温度。

POM is also known as Polyoxymethylene (POM). Regular molecular structure and crystallinity make its physical and mechanical properties very excellent, known as metal plastics. POM is a milk colored opaque crystalline linear thermoplastic resin with good comprehensive properties and colorability, high elastic modulus, high rigidity and hardness, and its specific strength and rigidity are close to that of metal; it has excellent tensile strength, bending strength, creep resistance, fatigue resistance, repeated impact resistance, excellent load recovery, low friction coefficient, good wear resistance and dimensional stability, Good surface luster, high viscoelasticity, small water blowing property, excellent electrical insulation, and not affected by temperature; excellent chemical resistance, except for strong acid, it has vibration absorption and noise elimination; small water absorption, good insulation resistance, and not affected by humidity; excellent chemical resistance: except for strong acid, phenol and organic halide, it is stable to other chemicals, and resistant to oil; its mechanical properties are affected by temperature The effect is small and the deformation temperature is high.

POM又称“赛钢”: 具备良好的机械强度及耐磨性，适合制作比较精密的塑料轴承，其良好的自润滑性能及低的磨擦系数，在保持塑料轴承传统优势的基础上，可应用于精密及较高转速运转。其中POM塑料轴承是所有塑料轴承中应用最为广泛的一种，一般内外球材料采用POM，保持架采用玻璃纤维增强的尼龙66（GRPA66—25）。滚珠为玻璃球，不锈钢球或陶瓷球，此种轴承碱性环境下表现良好但不适合在酸性腐蚀环境下运行。

POM also known as "saigang": with good mechanical strength and wear resistance, it is suitable for making more precise plastic bearings. Its good self-lubricating performance and low friction coefficient can be applied to precise and higher speed operation on the basis of maintaining the traditional advantages of plastic bearings. POM plastic bearing is one of the most widely used plastic bearings. Generally, POM is used for inner and outer balls, and grpa66-25 is used for cage. The ball is glass ball, stainless steel ball or ceramic ball. This kind of bearing performs well in alkaline environment, but it is not suitable for operation in acid corrosion environment.
