聚芳香酰胺MXD6(PARA)材料特性及其应用介绍

Application, medical cosmetology

聚芳香酰胺MXD6(PARA)材料特性及其应用介绍 一、PARA材料简介 一款轻质的高强度复合材料，30%碳纤维增强的密度是1.34g/立方厘米。 一般采用短玻璃纤维增强和长玻璃纤维LFT增强，也可以用碳纤维增CF增强，40%碳纤维增强后的PARA拉伸模量可达38.0Gpa。 特别适合取代笨重的，密度高，表面处理加工困难的金属材料！ 替代铝、镁 锌合金、铜等。 一种特殊的聚酰胺材料，属于高分子材料芳香族聚酰胺家族的一员！ 1988年诞生。 二、采用MXD6 (PARA)聚合物制作的部件具备突出特征： 高刚度。在 20 °C 时，N7GF1001拉伸模量高达 20 GPa。 卓越的耐机械应力性能。在 20 °C 时，挠曲强度可达 400 MPa。 易于加工。薄壁注塑时具有优良的注塑能力和高生产效率，即使采用高纤维含量也一样。 模具收缩率低。高的可重复性有助于实现精确成型，没有凹陷，可实现精密的尺寸要求。 微型化部件的概念。可注塑高刚度的复杂、细小形状。 优异的表面光泽性。增强后的产品具有优异的表面外观，即使采用高玻璃纤维含量也一样。 线性热膨胀系数低。其系数可与金属相比，适合与金属结合。 优异的热机械特性。在 140 °C 时，挠曲模量高达 7GPa。 蠕变性低。在 50 °C 和 50 MPa 作用下 1000 小时之 后，变形小于 1 %。 吸水速率缓慢。与所有聚酰胺一样，聚芳香酰胺对水有一定的敏感性。尽管如此，与采用普通聚酰胺的模塑部件相比，聚芳香酰胺的半芳香性质使 APEXPARA复合物仅产生较低且较缓慢的吸水性，与前者相比对湿度的敏感性低得多。 1. 优异的表面光泽性 表面加工：可以喷漆,也可以电镀。 2. 模具收缩率低 模具收缩率流动方向是0.1%，非流动方向是0.3%； 3. 良好的尺寸稳定性…
