聚甲醛原材料天然色

耐热性

聚甲醛原材料耐热性差，在成型温度下容易降解和释放乙醛。通常，在造粒过程中添加稳定剂。热变形温度高，均聚度136°C，共聚度110°C，在高于220°C的温度下分解形成甲醛气体，可在140°C下短期使用，长期使用温度为-40~100℃。

耐候性

普通聚甲醛原料耐候性差，长期暴露在大气中会老化。长期暴露在紫外线下，机械性能降低，表面呈粉末状并开裂。增加户外使用的稳定器

化学

聚甲醛原材料具有很强的耐化学性，耐有机溶剂、油类、弱酸弱碱。除了强酸、苯酚和有机卤化物，它们对其他化学物质也很稳定。聚甲醛在所有工程塑料中都耐有机溶剂，并且具有优异的耐溶剂性和耐油性。其色母粒的生产也比普通树脂要求更高。由于其结晶性，聚甲醛不能用染料染色

电气性能：

聚甲醛原材料具有良好的电气绝缘性，几乎不受温度和湿度的影响；它们具有优异的耐电弧性，可以在高温下保持

Heat resistance

POM raw materials have poor heat resistance and are easy to degrade and release acetaldehyde at the molding temperature. Usually, stabilizers are added during the granulation process. It has a high heat distortion temperature, with a degree of homopolymerization of 136°C and a degree of copolymerization of 110°C. It decomposes to form formaldehyde gas at a temperature higher than 220°C. It can be used at 140°C for short-term use, and the long-term use temperature is -40~100°C.

Weather resistance

Ordinary POM raw materials have poor weather resistance and will age when exposed to the atmosphere for a long time. Under long-term exposure to ultraviolet light, the mechanical properties are reduced, and the surface is powdered and cracked. Add stabilizer for outdoor use.

Chemical

POM raw materials have strong chemical resistance, resistance to organic solvents, oils, weak acids and weak bases. In addition to strong acids, phenol {TodayHot} and organic halides, they are also stable to other chemicals. Polyoxymethylene is resistant to organic solvents in all engineering plastics, and has excellent solvent resistance and oil resistance. The production of its color masterbatch is also much more demanding than ordinary resin. Due to its crystallinity, polyoxymethylene cannot be colored with dyes.

Electrical performance:

POM raw materials have good electrical insulation and are almost unaffected by temperature and humidity; they have excellent arc resistance and can be maintained at high temperatures.
