日本宝理 POM M25S 原装进口 一手货源
聚甲醛是一种表面光滑、有光泽的硬而致密的材料,淡黄或白色,薄壁部分呈半透明。燃烧特性为容易燃烧,离火后继续燃烧,火焰上端呈黄色,下端呈蓝色,发生熔融滴落,有强烈的刺激性甲醛味、鱼腥臭。聚甲醛为白色粉末,一般不透明,着色性好, 比重1.41-1.43克/立方厘米,成型收缩率1.2-3.0%,成型温度170-200℃ ,干燥条件80-90℃ 2小时。POM的长期耐热性能不高,但短期可达到160℃,其中均聚POM短期耐热比共聚POM高10℃以上,但长期耐热共聚POM反而比均聚POM高10℃左右。可在-40℃~100℃温度范围内长期使用。POM极易分解,分解温度为240度。分解时有刺激性和腐蚀性气体发生,故模具钢材宜选用耐腐蚀性的材料制作。
(1)POM是结晶型塑料,密度为1.42g/cm3,它的钢性很好,俗称“赛钢”.
(2)它具有耐疲劳、耐蠕变、耐磨、耐热、耐冲击等优良的性能,且摩擦系数小,自润滑性好.
(3)POM不易吸湿,吸水率为0.22~0.25%,在潮湿的环境中尺寸稳定性好,其收缩率为2.1%(较大),注塑时尺寸较难控制,热变形温度为172℃,聚甲醛有均聚甲醛两种,性能不同(均聚甲醛耐温性好一点).
