高耐热性

良好的电气和介电性能

低吸水性

软消声增韧聚甲醛树脂

产品详细信息软消声增韧聚甲醛树脂的主要特点是：。POM在加工前无需干燥，在加工过程中预热（约80°C），这有利于产品尺寸的稳定性

2。透气性：聚甲醛的透气性很小，只有聚乙烯的一小部分

3。收缩率：POM的高结晶度导致非常高的收缩率，可高达2%~3.5%

4。力学性能：POM的力学性能良好，弹性模量高，摩擦系数低且稳定，耐磨性好，自润滑性好。它有很高的硬度和硬度。接近金属。它具有良好的尺寸稳定性、较低的吸水率、抗反复冲击性和较小的强度变化。其抗拉强度和模量接近钢材。良好的疲劳强度。它是热塑性材料中耐疲劳性能优异的品种。它能承受100多万次重复荷载。它具有很高的抗蠕变和应力松弛能力。力学性能随温度变化不大，共聚反应略大于均聚反应

5。耐热性：POM耐热性差，在成型温度下容易降解和释放甲醛。通常，在造粒过程中添加稳定剂。其热变形温度高，均聚温度为136℃，共聚温度为110℃。在220°C以上分解并产生甲醛气体。它可以在140°C的温度下短期使用，长期使用温度为-40到100°C。

6。耐候性：POM的耐候性较差。长期暴露在大气中会老化。在紫外光的长期作用下，材料的力学性能下降，表面粉化开裂。户外应用应添加稳定剂

7。电气性能：聚甲醛具有良好的电气绝缘性，几乎不受温度和湿度的影响；它具有优异的耐电弧性，可在高温下保持

Product Details

Soft silencing and toughening POM Price Resin

The main features of POM:

1. There is no need to dry the POM before processing, and it is preheated (about 80°C) during the processing, which is good for the stability of the product size.

2. Air permeability: The air permeability of POM is small, only a fraction of that of PE.

3. Shrinkage rate: The high degree of crystallinity of POM leads to a very high shrinkage rate, which can be as high as 2%~3.5%.

4. Mechanical properties: The mechanical properties of POM are quite good, with high elastic modulus, low and stable friction coefficient, good wear resistance, and good self-lubrication. It has high hardness and rigidity. Close to metal. It has good dimensional stability, low water absorption, resistance to repeated impacts, and small changes in strength. Its tensile strength and modulus are close to steel. Good fatigue strength. It is a variety with excellent fatigue resistance among thermoplastic materials. It can withstand more than one million repeated loads. It has high resistance to creep and stress relaxation. The mechanical properties change little with temperature, and the copolymerization is slightly larger than the homopolymerization.

5. Heat resistance: POM has poor heat resistance and is easy to degrade and release formaldehyde at the molding temperature. Generally, stabilizers are added during granulation. It has a high heat distortion temperature, 136°C for homopolymerization and 110°C for copolymerization. Decomposes above 220°C and produces formaldehyde gas. It can be used at 140°C for short-term use, and long-term use temperature is -40 to 100°C.

6. Weather resistance: POM has poor weather resistance. It will age after long-term exposure to the atmosphere. Under the action of ultraviolet light for a long time, the mechanical properties will decrease, and the surface will be powdered and cracked. Stabilizers should be added for outdoor applications.

7.Electrical properties: POM has good electrical insulation and is hardly affected by temperature and humidity; it has excellent arc resistance and can be maintained at high temperatures.
