Our company has been supplying the following nylon models for a long time：
PA66 and PA6 are the main varieties of nylon, oupying an absolute dominant ition. ong the five engineering pstics, PA66 and PA6 he the rgest yield, the most varieties and the most widely used varieties. Nylon 6 is polycaproct, while nylon 66 is polyhexanediine, and nylon 66 is 12% harder than nylon 6; next are nylon 11, nylon 12, nylon 610, nylon 612, and nylon 1010, nylon 46, nylon 7, nylon 9, and nylon 13. New varieties include nylon 6I, nylon 9t and special nylon MXD6 (barrier resin). There are many varieties of nylon modified, such as reinforced nylon, nylon 610 and nylon 612 Monomer casting nylon (MC nylon), reaction injion molding (RIM) nylon, aromatic nylon, tranrent nylon, high impact (super tough) nylon, elropted nylon, conductive nylon, fle retardant nylon, blends and alloys of nylon and other polymers meet different special requirements, and are widely used as substitutes for traditional materials such as metal and wood.

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.

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，商品牌号达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。

为了提高 PA66 的机械特，经常加入各种各样的改剂。玻璃就是常见的添加剂，有时为了提高抗冲击还 加入合成橡胶，如 EPDM 和 SBR 等。
In order to improve the mechanical properties of PA66, various modifiers are often added. Gss is the most coon additive, and sometimes synthetic rubber, such as EPDM and SBR, is added to improve the impact resistance.
