PPO NORYLGTX830 是世界五大通用工程塑料之一。它具有刚性大、耐热性高、难燃、强度较高电性能优良等优点。聚苯醚还具有耐磨、无毒、耐污染等优点。PPONORYLGTX830 的介电常数和介电损耗在工程塑料中是*小的品种之一,几乎不受温度、湿度的影响,可用于低、中、高频电场领域。PPONORYL GTX830 的负荷变形温度可达 190℃以上,脆化温度为-170℃。PPO材料作为世界五大通用工程塑料之一,无毒,相对密度小,(PPO/PA同类产品也仅为1.10-1.13g/cm3),是五大通用工程塑料中密度*小的,具有良好的机械强度,抗蠕变性,耐应力松弛,抗疲劳强度高。
纯的PPO NORYLGTX830 料具有熔融流动性较差、价格高的缺点,市场出售的产品均为其改良的产品,具有优良的综合性能,它们广泛运用于:
电子电气:能够满足在潮湿、负载、高温的条件下具有优良的电绝缘性,运用制备电视积机调谐片、线圈芯、微波绝缘件、屏蔽套、高频印刷电路板,各种高压电子元器件,电视机、电脑、传真机、复印机外壳等。
汽车工业:适用于仪表板件、窗框、减震器、泵过滤网等。
机械工业:用作齿轮、轴承、泵叶轮、鼓风机叶轮片等。
化工领域:用于制作管道、阀门、滤片及潜水泵等耐腐蚀零部件
1:非结晶料、吸湿小,PPO的吸水率很低,但水分会使制品表面出现银丝、气泡等缺陷,为此,可将原料置于80~1OOC的烘箱申,干燥1-2h后使用。
2:PPO的分子键刚性大,玻璃化转化温度高,不易取向,但强迫取向后很难松弛。制品内残余内应力较高,一般要经过后处理。
3:PPO为无定型材料,在熔融状态下的流变性接近于牛顿流体,但随温度的升高偏离牛顿流体的程度越大。
4:PPO熔体的粘度大,加工时应提高温度,并适当提高注射压力,以提高充模能力。
5:PPO的回料可重复使用,一般重复使用3次,其性能没有明显降低。
6:对PPO熔体宜采用螺杆式注塑机成型,喷嘴采用直通式为佳,孔径为3-6mm
7:在PPO注塑成型时,宜采取高压、高速注射,保压及冷却时间不能太长。
8:模具的主流道宜采用较大的锥度或采用拉料钩,浇道以短粗为好。
9:浇口宜采用直接式、扇形或扁平形,采用针状浇口时直径应适当加大,对于长浇道可采用热流道结构。
10:PPO的成型收缩率较小,一般为0.2%一0.7%,制品尺寸稳定性能优良。
11:流动性差,为类似牛顿流体,粘度对温度比较敏感,制品厚度一般在0.8毫米以上。极易分解,分解时产生腐蚀气体。宜严格控制成型温度,模具应加热,浇注系统对料流阻力应小。
12:聚苯醚的吸水率很低0.06%左右,但微量的水分会导致产品表面出现银丝等不光滑现象,**是作干燥处理,温度不可高出150度,否则颜色会变化。
