产品细节

注射挤出级天然彩色聚甲醛树脂

聚甲醛的拉伸强度可达70MPa，可在104℃下长期使用，脆化温度为-40℃，吸水率小。然而，聚甲醛的热稳定性较差，耐候性较差，长期暴露在大气中会老化。聚甲醛的机械性能相当好。其强度弹性模量高，摩擦系数小，耐磨性好。聚甲醛还具有很高的抗蠕变性和应力松弛性。聚甲醛对水的机械稳定性和吸水性影响不大。聚甲醛具有良好的介电性能，其介电常数和介电损耗角正切在较宽的频率和温度范围内变化不大。聚甲醛的耐热性差，在成型温度下容易降解和释放甲醛，稳定剂处于造粒状态。聚甲醛耐气候性差，大气老化后综合性能下降。但其化学稳定性非常优越，尤其是对于有机溶剂，其尺寸变化和力学性能下降很小。但对强酸和硝酸、硫酸等强氧化剂的耐腐蚀性较差

Product Details

natural color POM resin with Injection extrusion grade

The tensile strength of polyformaldehyde can reach 70 MPa, can be used for a long time at 104℃, the embrittlement temperature is -40℃, and the water absorption is small. However, the thermal stability of polyformaldehyde is poor, weathering resistance is poor, long-term exposure to the atmosphere will aging. The mechanical properties of polyformaldehyde are quite good. It has high strength elastic modulus, small friction coefficient and good wear resistance. Polyformaldehyde also has high creep resistance and stress relaxation. Polyformaldehyde has good dimensional stability and small water absorption, so the effect of water absorption on its mechanical properties can not be considered. Polyformaldehyde has good dielectric properties, and its dielectric constant and dielectric loss angle tangent change little in a wide range of frequency and temperature. The heat resistance of polyformaldehyde is poor, it is easy to degrade and release formaldehyde at molding temperature, and stabilizer is in granulation. The climate resistance of polyformaldehyde is poor, and the general performance decreases after atmospheric aging. But its chemical stability is very superior, especially for organic solvents, its size change and mechanical properties decrease very little. but poor corrosion resistance to strong acids and strong oxidants such as nitric acid and sulfuric acid.
