PEEK high-performance polymer
Polyether ether ketone (PEEK) is a semi‑crystalline, high‑performance specialty engineering plastic whose main chain consists of repeating units of ether and ketone linkages. It can withstand long‑term service temperatures up to 260°C and exhibits excellent chemical resistance, hydrolytic stability, as well as outstanding mechanical strength and dimensional stability. PEEK is widely used in cutting‑edge industries such as aerospace, medical devices, semiconductor manufacturing, and the petrochemical sector.
Introduction to PEEK Properties
耐高温性能
•Tg = 143℃ •Tm = 343℃ 长期使用温度（CUT）普遍可达260℃，且部分改性产品热变形温度（HDT）可达320℃。
耐低温性能
在-196℃的超低温环境下仍能保持良好的力学性能。
耐辐射性能
γ辐照剂量达1100Mrad时仍能保持良好的绝缘能力，保留良好的机械性能。
高强度
经增强改性后，其比强度可超越钢材、铝合金等常用金属材料。
耐疲劳性能
在交变应力作用下抗疲劳性能突出，适用于长周期齿轮等极限疲劳场景。
耐蠕变性能
在50%拉伸强度应力水平下，持续1000小时的蠕变量低于0.5%，尺寸稳定性优异。
耐磨性能
具有优良的滑动特性，适用于要求低摩擦系数和长期耐磨耗的应用场景。
耐化学腐蚀性能
除浓硫酸外，不溶于绝大多数有机溶剂及强酸、强碱，且耐水解性能优异。
电学性能
在宽泛的温度和频率范围内均表现出良好的电绝缘性能，高频下介电损耗较低。
热学性能与加工性
可在340~420℃较宽温度范围内进行注塑、挤出等热塑性加工，热分解温度高达550℃。
生物相容性
具有优异的生物相容性，无任何的副作用，且符合ISO10993标准的所有要求。
低烟阻燃
在不添加任何阻燃剂的情况下，即可达到UL的94V-0级阻燃等级，且燃烧时发烟量低。
低密度
密度约为1.3 g/cm³，改性后仍显著低于同等强度金属材料，有利于轻量化设计。
