耐高温和低温的pa66改性材料

干燥处理：如果材料在加工前密封，则无需干燥。但是，如果打开储存容器，建议在85℃的热空气中干燥。如果湿度大于0.2%，则需要在105°C下真空干燥12小时

PA66熔融温度：260~290C。玻璃添加剂的产品温度为275~280C。熔化温度应避免高于300℃。模具温度：建议为80摄氏度。模具温度会影响结晶度，结晶度会影响产品的物理性能。对于薄壁塑料零件，如果使用低于40℃的模具温度，塑料零件的结晶度将随时间而变化。为了保持塑料零件的几何稳定性，需要进行退火处理

pa66改性材料耐高温和低温压力：通常为750~1250bar，具体取决于材料和产品设计

速度：高速（对于增强材料，速度略低）。浇口和浇口：由于PA66的固化时间很短，浇口的位置非常重要。闸门孔径不应小于0.5*t（其中t是塑料件的厚度）。如果使用热流道，浇口尺寸应小于常规流道，因为热流道有助于防止材料过早凝固。如果使用水下闸门，闸门直径应为0.75mm。PA66的典型应用更广泛地应用于汽车工业、仪表外壳和其他要求抗冲击性和高强度的产品中

Product Details

pa66 modified material resistant to high temperature and low temperature

Drying treatment: If the material is sealed before processing, then there is no need to dry it. However, if the storage container is opened, it is recommended to dry it in 85C hot air. If the humidity is greater than 0.2%, vacuum drying at 105°C for 12 hours is required.

PA66 melting temperature: 260~290C. The glass additive product is 275~280C. The melting temperature should be avoided higher than 300C. Mold temperature: 80C is recommended. The mold temperature will affect the crystallinity, and the crystallinity will affect the physical properties of the product. For thin-walled plastic parts, if a mold temperature lower than 40C is used, the crystallinity of the plastic parts will change over time. In order to maintain the geometric stability of the plastic parts, annealing treatment is required.

Pressure: usually 750~1250bar, depending on material and product design.

Speed: high speed (slightly lower for reinforced materials). Runner and gate: Since the solidification time of PA66 is very short, the location of the gate is very important. The gate aperture should not be less than 0.5*t (where t is the thickness of the plastic part). If you use a hot runner, the gate size should be smaller than the conventional runner, because the hot runner can help prevent premature solidification of the material. If using a submerged gate, the diameter of the gate should be 0.75mm. Typical applications PA66 is more widely used in the automotive industry, instrument housings and other products that require impact resistance and high strength.
