POM CELCON M90AW
特点
(1)POM加工前可不用干燥,最好在加工过程中进行预热(80℃左右),对产品尺寸的稳定性有好处.
(2) POM的加工温度很窄(0~215℃),在炮筒内停留时间稍长或温度超过220℃时就会分解,产生刺激性强的甲醛气体.
(3) POM料注塑时保压压力要较大(与注射压力相近),以减少压力降.螺杆转速不能过高,残量要少;
(4) POM产品收缩率较大,易产生缩水或变形.POM比热大,模温高(80~100℃),产品脱模时很烫,需防止烫伤手指.
(5) POM宜在“中压、中速、低料温、较高模温”的条件下成型加工,精密制品成型时需用控制模温
(6)具高机械强度和刚性
(7)最高的疲劳强度
(8)环境抵抗性、耐有机溶剂性佳
(9)耐反覆冲击性强,良好的电气性质,复原性良好,具自已润滑性、耐磨性良好,尺寸安定性优.
应用
.可代替大部分有色金属、汽车、机床、仪表内件、轴承、紧固件、齿轮、弹簧片、管道、运输带配件、电水煲、泵壳、沥水器、水龙头等.
