PA66耐高温塑料颗粒

PA66、聚酰胺66或尼龙66。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。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

尼龙66耐高温塑料颗粒，其粘度对温度变化非常敏感。PA66的收缩率在1%~2%之间，加入垂直于工艺方向的玻璃纤维添加剂。PA66对许多溶剂都有溶解性抗性，但对酸和其他氯化剂的抗性较弱

PA66常见问题解答

闪光、气泡、凹痕、焊痕、烧焦和黑线、银线和标记、表面划痕、表面雾和图案、烧焦变色和杂质、烧焦黑、光泽差、裂纹和白化、颜色不均匀、易碎、分层、翘曲和变形、脱模不良、严重的模具腐蚀

PA66 High Temperature Resistant Plastic Particles

Product Details

PA66 high temperature resistant plastic particles

PA66, polyamide 66 or nylon 66. 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. 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.

PA66 high temperature resistant plastic particles，Its viscosity is very sensitive to temperature changes. The shrinkage rate of PA66 is between 1%~2%, adding glass fiber additives perpendicular to the process direction. PA66 has solubility resistance to many solvents, but weak resistance to acids and other chlorinating agents.
