PEEK 和 PEI (Ultem) 怎么选? 哪个更适合医疗应用?

PEEK 耐温更高 (连续 250°C vs PEI 170°C)、耐化学更好 (除浓硫酸外几乎不溶)、机械强度高 30%、价格高 3-5 倍。PEEK 是骨科器械、植入物辅助、长期灭菌件首选; PEI 适合短期医疗设备外壳、蒸汽灭菌件, 性价比更高。

PEEK 牌号 Victrex 450G 和国产 550G 性能差距多大?

Victrex 450G 是医疗级金标, 批次稳定性、ISO 10993/USP Class VI 认证完整; 国产吉林中研 550G 性能可达 90% (密度/熔点/Tg 接近), 但批次一致性、纯度、医疗认证略差。医疗器械推荐 450G, 半导体/工业 550G 完全够用且便宜 50%+。

PEEK 注塑温度多高? 需要什么特殊设备?

PEEK 熔点 343°C, 注塑需 360-400°C 料筒温度、模具 170-200°C, 必须用 400°C+ 耐高温料筒和陶瓷加热圈。干燥 150°C × 4-6h, 含水率 < 0.02%。加工窗口窄, 新手建议先试模。

PEEK 能用 3D 打印吗? 推荐什么工艺?

PEEK 适合 FDM (熔丝沉积) 和 SLS (选择性激光烧结) 3D 打印, 但需要 350°C+ 热床和 100°C+ 腔体温度, 设备要求高。Victrex 450G 打印件已用于医疗定制植入物原型; 但打印件强度比注塑件低 20-30%, 仅适合原型/小批量。
