WHAT IS PBT PC+PBT PC/PBT PLASTIC RESIN ALLOY？

Application, Science and Technology

PC/PBT Resin Plastic Material Blend (polycarbonate / polyester blend) is a thermoplastic alloy of amorphous polycarbonate and semi-crystalline polyester (either polybutylene terephthalate or polyethylene terephthalate). PC/PBT provides a combination of chemical resistance, temperature resistance, and mechanical strength. Our polymer compounding technology allows us to prepare alloys of Polycarbonate (PC) and Polyesters (either PBT or PET). PBT Material Properties…

国产改性替代材料PARA MXD6半芳香聚酰胺的特性及应用

Application, Science and Technology

PARA MX-Nylon MXD6是一种半结晶，半芳香聚酰胺，由间二甲苯二胺组成。 与尼龙6、6/6和12相比，mx -尼龙提供了优越的拉伸和弯曲强度，同时具有一半的水分敏感性。PARA MX-Nylon MXD6还提供了对氧气和二氧化碳的优越的气体屏障性能，可用于医疗包装，作为乙烯-乙烯醇(EVOH)，丙烯腈(PAN)，聚氯乙烯(PVDC)共聚物的替代品。 尼龙- mxd6是一个通用名称给予广泛的聚酰胺生产的间二甲二胺(MXDA)由三菱气体化学公司，印第安纳州。 Solvay 公司生产的LXEF系列材料是目前制造业使用最广泛的MXD6材料。 它是由MXDA与己二酸缩聚而成的结晶聚酰胺。 不同于尼龙6和尼龙66，尼龙- mxd6是一种脂肪族聚酰胺，其主链中含有一个芳香环。参见如下所示的化学结构。 Nylon-MXD6 与尼龙6和尼龙66相比，尼龙- mxd6具有以下优点: 更高的强度和弹性模量; 高玻璃化转变温度; 吸水性、透湿性低; 良好的结晶速度和易于成型和制造; 优秀的气体屏障属性。 在较宽的温度范围内具有优异的机械强度模量 吸水率较普通聚酰胺低，在吸水条件下尺寸和机械强度变化减小 热变形温度高，热膨胀系数低，相当于金属合金 优良的耐油性和有机溶剂的耐化学性 模具收缩小，翘曲小，适用于精密模具制品 即使玻璃纤维含量高，表面光洁度也很好 这些特点导致尼龙- mxd6作为包装和成型材料，以及在单丝生产的应用大大不同。 尼龙mxd6对氧气和二氧化碳具有优良的气体阻隔性能。在一定条件下，它的气阻性能超过了乙烯乙烯醇(EVOH)、偏氯乙烯(PVDC)和丙烯腈(PAN)等共聚树脂。 尼龙mxd6的成型规格与其他材料的成型标准符合良好。这意味着可以将尼龙- mxd6与聚对苯二甲酸乙二醇酯(PET)、聚丙烯(PP)或聚乙烯(PE)结合使用，实现共注射成型和共挤压成型，以生产层压容器、瓶子和包装片。 MX-Nylon is a semi-crystalline, semi-aromatic polyamide, comprised on meta-xylene diamine. MX-Nylon offers superior tensile and flexural strength when compared to Nylon 6,…
