PA66简介：尼龙（Nylon），中文名聚酰胺，英文名称Polyide（简称PA），是分子主链上含有重复酰胺基团—[NHCO]—的热塑树脂总称。其命名由合成单体具体的碳原子数而定。是美国的化学工业公司──杜邦公司化学家卡罗瑟斯和他的科研小组发明的。 尼龙PA66；聚己二酰己二胺；英文名：Polyide 66，缩写 nylon 66。 CAS编号：32131-17-2 尼龙PA66是PA系列中机械强度、应用广的品种,因其结晶度高,故其刚、耐热都较高.
PA66的发展：PA66在40年末期美国DoPont公司实现PA66工业化生产,目前世界上尼龙树脂按结构分大约有20多种，商号达800馀种。以尼龙大分子中重复单元的碳原子数目来确定其产品名称，通式可写尼龙或PA。有PA6、PA66、PA11、PA12、PA610、PA612、PA1010、PA46、PA6T、PA9T等。其中以品种PA6、PA66为主，二者约占PA工程塑料总量的92%左右。
The development of PA66: in the te 1940s, Dopont company in the United States realized the industrial production of PA66. At present, there are more than 20 kinds of nylon resins in the world aording to their structures, with more than 800 brand numbers. The product ne is determined by the number of carbon atoms in the repeating unit of nylon macromolecule. The general formu can be written as nylon or Pa. There are PA6, PA66, PA11, PA12, PA610, pa612, PA1010, PA46, PA6T, PA9T, etc. ong them, PA6 and PA66 are the main varieties, aounting for about 92% of the total ount of PA engineering pstics.
Zytel PA66 / 6 uses pstics for sporting goods:
Helmet manucturer DXL protion chooses DuPont ™ Zytel Nylon resin is due to its high resistance, rigidity and toughness. This super tough nylon is reinforced with 33% gss fiber. The four helmet parts made with Zytel are the , the C-shaped "buckle" around the head and two side s. The patented four part design makes the helmet more suitable for the head than the traditional one part helmet.
Runner and gate of PA66 processing: because the solidification time of PA66 is very short, the location of gate is very important. The gate dieter should not be less than 0.5 * t (where t is the thickness of the pstic part). If a hot runner is used, the gate size should be smaller than that of a conventional runner, as the hot runner can help prevent premature solidification of the material. If a submerged gate is used, the minimum dieter of the gate should be 0.75.
