一 聚苯醚PPE
聚苯醚化学名称为聚2,6-二甲基-1,4-苯醚, PPE(Polypheylene ether) 或简称PPO( Polyphenylene Oxide)。又称为聚亚苯基氧化物或聚苯撑醚,是一类耐高温的热塑性树脂。市场上通用的主要为改性的聚苯醚(Modified Polyphenylene Oxide),简称MPPO,或者MPPE(Modified Polypheylene ether)。由于习惯上,对聚苯醚和其改性共混聚合物都称为PPE(美国叫法)或PPO(日本叫法),本文也采用通俗称法:以下称为PPE或PPO。
二、聚苯醚PPE特性 PPE是一种综合性能优良的热塑性工程塑料,突出的是电绝缘性和耐水性优异,尺寸稳定性好。
1.介电性能居工程塑料:PPE树脂分子结构中无强极性基团,电性能稳定,可在 广泛的温度及频率范围内保持良好的电性能。其介电常数和介电损耗角正切是工程塑料中zui
小的,且几乎不受温度、湿度及频率数的影响。其体积电阻率是工程塑料中zui高的。PPE的优异电性能使其广泛应用于生产电器产品,尤其是耐高压的部件,如彩电的行输出变压器( FBT)等。
2.良好的机械性能及热性能:PPE子链中,含有大量的芳香环结构,分子链感性较强。
树脂的机械强度较高,耐蠕变性优良,温度变化影响甚小。PPE具有较高的耐热性,玻璃化温度高达211℃,熔点268℃。
本公司 可以免费提供各种材料物性及各种材质认证 如:SGS UL MSDS ROHS MDS 等证明 : 通过这些链接您能够访问供应商资料。我们尽量保证 准确数据资料; UL 黄卡含有 UL 验证的易燃性和电气特性物性说明
3.优异的耐水性:PPE为非结晶性树脂,在通常的温度范围,分子运动少,主链中无 大的极性基团,偶极矩不发生分极,耐水性非常好,是工程塑料中吸水率zui低的品种。在热水中长时间浸泡其物理性能仍有很少下降。4.阻燃性良好,具有自熄性:PPE的氧指数29,为自熄材料,而高抗冲击性聚苯乙烯的氧指数17为易燃性材料,二者合一是具中等程度的可燃性,制造阻燃等级PPE时,不需要添加卤素的阻燃剂,加入含磷类阻燃剂即可达到UL94标准,减少对环境的污染。
5.收缩率低,尺寸稳定性好;无毒,密度小。
6.耐介质性和耐光性:PPE对酸、碱和洗涤剂等基本不受腐蚀,在受力的情况下,矿 物油及酮类、酯类溶剂会产生应力开裂;对有机溶剂如脂肪烃、卤代脂肪烃和芳香烃等会使之融涨和溶解。PPE弱点是耐光性差,长时间在阳光或荧光灯下使用产生变色,颜色发黄,原因是紫外线能使芳香醚的链结合分裂所致。而如何改善PPE的耐光性成为一个课题。
三、聚苯醚(PPE)成型工艺
PPE可通过注塑、挤出等工艺加工成各种制品:
1.注塑:柱塞式或螺杆式注塑机都能加工PPE。一般采用螺杆式注塑机,要求长径比大于15:1,压缩比1.7 ~4.0(一般采用2.5~3.5)。
2.挤出:PPE能在挤出机上加工成管、片、棒、块等。采用排气式、长径比大的挤出机。

产品说明 | ||||
Modified polyphenylene ether (PPE), high heat resistant, 20 % glass-fiber reinforced VESTORAN X7342 is the registered trademark of the Evonik Degussa GmbH for molding compounds containing poly-2,6-dimethyl-1,4-phenylene ether as polymeric constituent (poly-phenylene ether, PPE, also referred to as PPO). As a material of amorphous structure, VESTORAN X7342 shows very small mold shrinkage. Therefore molded parts have a very low tendency to warp. Moldings of VESTORAN X7342 are dimensionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN X7342 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions. Due to the glass-fiber reinforcement the compound combines outstanding heat deflection temperature under load with high strength and rigidity. The even smaller shrinkage compared to non-reinforced VESTORAN depends on the orientation of the glass fibers in the molded part. | ||||
