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, suitable for plastic/rubber composites manufactured by the K&K process VESTORAN is the registered trademark of 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 1900 shows very small mold shrinkage. Therefore molded parts have a very low tendency to warp. The impact modified compound is of low density and easy to process. Further properties are excellent impact strength, heat deflection under load and suitability for being coated with lacquers. Moldings of VESTORAN 1900 are dimensionally stable and hydrolysis resistant even in hot water, but are more sensitive to organic solvents than semi-crystalline plastics. VESTORAN 1900 is resistant to aqueous alkalines and acides, certain alcohols, and glycol solutions. Colored material contains only cadmiumfree pigments. VESTORAN 1900 is particularly suitable for the adhesion promoter-free manufacturing of plastic/ rubber composites by the Evonik Degussa GmbH-patented K&K process. | |
