PEEK注射级塑料颗粒
PEEK可以按照热塑性方法进行加工，如注射、挤压、压制、吹塑和静电喷涂，但加工条件相对苛刻。PEEK的熔点高达334°C，但超过熔点后，它具有熔体流动性和高熔体热稳定性。当剪切速率为1000/s时，360°C下的熔体粘度为480Pa。s、 380℃时为400Pa。s、 400℃时为350Pa。s、 可以看出，随着温度的升高，熔体粘度显著降低，熔体的热稳定性也很好。如果在400°C下保持1小时，则不会影响其流动性。这是一个熔体加工粘度更高的聚醚醚酮。这提供了可能性，但PEEK的熔融温度比普通塑料高100℃以上，熔体粘度也相对较大。因此，注射过程中对设备的要求更高。注塑机加热系统一般要求达到400℃，注塑压力可达150MPa，模具温度可达160℃。PEEK可以通过挤出成型生产薄膜、管道、单丝、金属丝涂层和其他产品。PEEK非拉伸薄膜结晶度低，强度和耐热性不理想。通常通过拉伸和热处理来改善。拉伸和热处理后的PEEK膜的熔点比PET膜高80°C，其强度与苯型PI膜相似，其耐湿性和耐化学性优于苯型PI膜

Product Details
PEEK injection grade plastic granules
PEEK can be processed in accordance with thermoplastic methods such as injection, extrusion, pressing, blow molding, and electrostatic spraying, but the processing conditions are relatively harsh. The melting point of PEEK is as high as 334°C, but after it exceeds the melting point, it has melt fluidity and high melt thermal stability. When the shear rate is l000/s, the melt viscosity at 360°C is 480Pa. s, 400Pa at 380℃. s, 350Pa at 400℃. s, it can be seen that the melt viscosity decreases significantly with the rise of temperature, and the thermal stability of the melt is also very good. It will not affect its fluidity if it is kept at 400°C for 1h. This is a PEEK with a higher viscosity for melt processing. It provides the possibility, but the melting temperature of PEEK is more than 100℃ higher than that of general plastics, and the melt viscosity is also relatively large. Therefore, the requirements for equipment during injection are higher. Generally, the heating system of the injection machine is required to reach 400℃, and the injection pressure It can reach 150MPa, and the mold temperature can reach 160℃. PEEK can produce films, pipes, monofilaments, wire coatings and other products through extrusion molding. PEEK unstretched film has low crystallinity, and its strength and heat resistance are not ideal. It is generally improved by stretching and heat treatment. The PEEK film after stretching and heat treatment has a melting point of 80°C higher than that of the PET film, and its strength is similar to that of the benzene-type PI film, and its moisture resistance and chemical resistance are better than that of the benzene-type PI film.
