Vestamidcare ML等级涵盖了一系列不同粘度的聚酰胺12树脂,可通过挤压或注射成型进行加工。Vestamicare ML产品系列包括不稳定的基础树脂以及稳定或增强的化合物。维斯塔明护理ML树脂具有耐冲击、耐缺口冲击、尺寸稳定性好、滑动性能好、耐磨性高、耐化学品等优良性能。例如,未填充的Vestamid Care ML等级是导管和导管的首选材料,其中Vestamid Care ML材料在血管成形术球囊导管等应用中遇到了更高的挑战。增强型Vestamid Care ML等级的典型应用领域包括外壳部件、监控和成像设备以及耐用医疗设备。由于其低吸水性,填充维斯汀护理毫升级甚至抵制蒸汽高压灭菌超过500个周期。优点:高抗冲击性、高尺寸稳定性、高耐化学性、低滑动摩擦性、高韧性、高耐磨性、易加工性、着色性 VESTAMID®Care ML grades cover a range of polyamide 12 resins of different viscosity for processing via extrusion or injection molding. The VESTAMID®Care ML product range consists of unstabilized base resins as well as stabilized or reinforced compounds. VESTAMID® Care ML resins are characterized by several outstanding properties, such as high impact & notched impact resistance, dimensional stability, good sliding properties, high abrasion resistance and resistance against chemicals. Unfilled VESTAMID® Care ML grades are for example the materials of choice for catheters and tubings, where VESTAMID® Care ML materials meet even highest challenges in applications such as angioplasty balloon catheters. Typical areas of application for reinforced VESTAMID® Care ML grades include housing-parts, monitoring and imaging devices and durable medical equipment. Due to their low water uptake, filled VESTAMID® Care ML grades even resist steam autoclaving for more than 500 cycles. The advantages at a glance : High impact resistance High dimensional stability High chemical resistance Low sliding friction High toughness High abrasion resistance Easy processability & colorability |
