POM日本宝理M25-44特性
长时间、较宽的温度范围内，能保持拉伸强度、拉伸率及冲击强度等各种机械特性的平衡。
在较宽的温度范围内和长时间受负载的条件下，显示出优良的耐蠕变性能。
具有优良的耐疲劳性，即使是在重复应力或连续振动的条件下，也不会发生疲劳破坏，仍然保持着较安定的性能。
具有高刚性及优良的弹性恢复性能，再加上良好的耐疲劳性和耐蠕变性，作为弹簧材料被广泛应用。
耐磨耗性为热塑性塑料之，同时它还具有良好的润滑性。此外，材料本身也具有自润滑性，适用于不可使用润滑油的部件。
不仅具有良好的短期热性（如熔点、热变形温度等），即使在高温空气及高温热水中长期使用，亦可呈现出良好的性能。
由于吸水引起尺寸变化的可能性很小，故在实际应用几乎不成为问题。
除强酸、强氧化剂的化学药品外，对无机化学药品、油类具有良好的耐化学性。
具有良好的流动性及漂亮的外观，是极易成型的材料。
它既可以嵌入成型，也可以嵌出成型。此外还可以进行切削加工、熔接、印刷等二次加工
In a long time and wide temperature range, it can maintain thebalance of various mechanical properties such as tensile strength,tensile rate and impact strength.
It shows excellent creep resistance in a wide temperature rangeand under long-term load conditions.
It has excellent fatigue resistance. Even under the condition ofrepeated stress or continuous vibration, fatigue damage will notoccur, and it still maintains relatively stable performance.
With high rigidity and excellent elastic recovery performance,plus good fatigue resistance and creep resistance, it is widelyused as spring material.
Wear-resistance is one of the thermoplastics, and it also hasgood lubricity. In addition, the material itself hasself-lubrication, which is applicable to parts that cannot uselubricating oil.
It not only has good short-term thermal properties (such asmelting point, thermal deformation temperature, etc.), but alsoshows good performance even if it is used in high-temperature airand high-temperature hot water for a long time.
Because the possibility of size change caused by waterabsorption is very small, it hardly becomes a problem in practicalapplication.
In addition to strong acid and strong oxidant chemicals, it hasgood chemical resistance to inorganic chemicals and oils.
With good fluidity and beautiful appearance, it is a very easyto form material.
It can be either embedded or embedded. In addition, it can alsocarry out secondary processing such as cutting, welding andprinting
