产品细节

PA66塑料原料改性

PA66在聚酰胺材料中具有较高的熔点。它是一种半结晶材料。PA66可以在较高温度下保持强大的强度和刚度。PA66成型后仍具有吸湿性，其吸湿程度主要取决于材料组成、壁厚和环境条件。在产品设计中，必须考虑吸湿对几何稳定性的影响

尼龙66塑料原材料改性

为了提高尼龙66的力学性能，经常添加各种改性剂。玻璃是最常见的添加剂。有时添加合成橡胶，如EPDM和SBR，以提高抗冲击性。PA66粘度低，所以流动性好（但不如PA6）。此属性可用于处理非常薄的组件。它的粘度对温度变化非常敏感。PA66的收缩率在1%~2%之间，加入玻璃纤维添加剂可使收缩率降至0.2%~1%。收缩率在工艺方向和垂直于工艺方向的方向上差异很大。A66 Zytel塑料原材料性能特征？PA66是机械强度最高、使用最广泛的PA系列。由于其结晶度高，其硬度和耐热性高。超声波焊接。低分子量。润滑良好。良好的可操作性。成型性能好，电气性能高，流动性高，耐化学性好，耐磨性好，耐疲劳性耐油，耐油脂性好，生产阶段的快速释放性能，等。

PA66 Plastic Raw Material Modification

Product Details

PA66 plastic raw material modification

PA66 has a higher melting point in polyamide materials. It is a semi-crystalline-crystalline material. PA66 can maintain strong strength and rigidity at higher temperatures. PA66 is still hygroscopic after molding, its degree mainly depends on the composition of the material, wall thickness and environmental conditions. In product design, the influence of moisture absorption on geometric stability must be considered.

PA66 plastic raw material modification

In order to improve the mechanical properties of PA66, various modifiers are often added. Glass is the most common additive. Sometimes synthetic rubber, such as EPDM and SBR, is added to improve impact resistance. PA66 has low viscosity, so it has good fluidity (but not as good as PA6). This property can be used to process very thin components. Its viscosity is very sensitive to temperature changes. The shrinkage rate of PA66 is between 1%~2%, adding glass fiber additives can reduce the shrinkage rate to 0.2%~1%. The shrinkage rate differs greatly in the process direction and the direction perpendicular to the process direction. A66 Zytel plastic raw material performance characteristics? PA66 is the PA series with the highest mechanical strength and the most widely used variety. Because of its high crystallinity, its rigidity and heat resistance are high. Ultrasonic welding. Low molecular weight. Good lubrication. Good workability. The molding performance is good, the electrical performance is high, the fluidity is high, the chemical resistance is good, the abrasion resistance is good, the fatigue resistance is oil resistance, the grease resistance is good, the quick release performance in the production stage, etc.
