聚醚醚酮(PEEK)是在主链结构中含有一个酮键和两个醚键的重复单元所构成的高聚物,属特种高分子材料。具有耐高温、耐化学药品腐蚀等物理化学性能,是一类半结晶高分子材料,可用作耐高温结构材料和电绝缘材料,可与玻璃纤维或碳纤维复合制备增强材料。一般采用与芳香族二元酚缩合而得的一类聚芳醚类高聚物。这种材料在航空航天领域、医疗器械领域(作为人工骨修复骨缺损)和工业领域有大量的应用。

1)PEEK塑胶原料注塑成型收缩率小,这对控制PEEK注塑零件的尺寸公差范围非常有好处,使PEEK零件的尺寸精度比通用塑料高很多;

2)热膨胀系数小,随着温度的变化(可由环境温度的变化或运转过程中摩擦生热引起),PEEK零件的尺寸变化很小;

3)尺寸稳定性好,塑料的尺寸稳定性是指工程塑料制品在使用或存放过程中尺寸稳定的性能,这种尺寸的变化主要是因为聚合物分子的活化能提高后,使链段有某种程度的卷曲导致的;

4)PEEK耐热水解特性突出,在高温高湿环境下吸水性很低,不会出现类似尼龙等通用塑料因吸水而使尺寸发生明显变化的情况。
