高强度PA66 美国奥升德 21SPC 增韧性 经润滑 抗溶解 注塑级

pa66是pa系列中机械强度高、应用广的品种,因其结晶度高,故其刚性、耐热性都较高。

特性编辑

pa66在聚酰胺材料中有较高的熔点。它是一种半晶体-晶体材料。pa66在较高温度也能保持较强的强度和刚度。pa66在成型后仍然具有吸湿性，其程度主要取决于材料的组成、壁厚以及环境条件。在产品设计时，一定要考虑吸湿性对几何稳定性的影响。

为了提高pa66的机械特性，经常加入各种各样的改性剂。玻璃就是常见的添加剂，有时为了提高抗冲击性还加入合成橡胶，如epdm和sbr等

pa66主要用于汽车、机械工业、电子电器、精密仪器等领域。从终用途看，汽车行业消耗的尼龙66占第一位，电子电器占第二位。大约有88%的尼龙66通过注射成型加工成各种制件，约12%的尼龙66则通过挤出、吹塑等成型加工成相应的制品。

pa66 has a high melting pointin polyamide materials. it is a semi crystalline material. pa66 canmaintain strong strength and stiffness at higher temperatures. pa66still has hygroscopicity after molding, and its degree mainlydepends on the material composition, wall thickness, andenvironmental conditions. when designing products, it is importantto consider the impact of moisture absorption on geometricstability.

in order to improve themechanical properties of pa66, various modifiers are often added.glass is the most common additive, and sometimes synthetic rubbersuch as epdm and sbr are added to improve impactresistance

pa66 is mainly used in fieldssuch as automobiles, mechanical industry, electronics, precisioninstruments, etc. from the perspective of end use, nylon 66consumed by the automotive industry ranks first, while electronicappliances rank second. about 88% of nylon 66 is processed intovarious parts through injection molding, while about 12% of nylon66 is processed into corresponding products through extrusion, blowmolding, and other molding processes.
