Founded in 1802 A company in the United States is a scientific research company. With its own innovative products, raw materials and services, it has demonstrated international level scientific research and engineering project capability for the world's sales market, and helped to solve various international challenges, including providing sufficient and healthy food for people all over the world and reducing dependence on non renewable resources, And its maintenance of life and the natural environment, so that people all over the world and all over the country have a happier, safer and healthier daily life. DuPont's business process covers more than 90 countries and regions all over the world, involving agriculture, animal husbandry and food, housing and engineering construction, communication and transportation, power, energy and microbial application of high technology and many other industries with common product innovation and service projects
Basic physical properties of PA66: PA66 is still the most important variety. The melting point, tensile strength, bending strength and hardness of PA66 are the highest in the nylon fily, so it is widely used in various fields. It can also maintain strong strength and stiffness at higher temperature. The melting point of PA66 is 260 ℃; it is a semi crystalline crystalline material. PA66 is resistant to many soents, but weak to acids and other Chlorinators. The shrinkage of PA66 is between 1% and 2%, which can be reduced to 0.2% - 1% by adding gss fiber additive. PA66 has low viscosity, so it has good fluidity. This property can be used to process very thin components. Its viscosity is sensitive to temperature changes. It still has hygroscopicity after molding, and its degree mainly depends on the comition of the material, wall thickness and environmental conditions. The influence of Hygroscopicity on geometric stability must be considered in product design.
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.
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.
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，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，一定要考虑吸湿对几何稳定的影响。
