PEEK-OPTIMA® Image Contrast (Low radiopacity) 聚醚醚酮 Invibio Inc. 产品说明: PEEK-OPTIMA® image contrast compounds, from Invibio® Biomaterial Solutions, offer implant manufacturers all the benefits of PEEK-OPTIMA polymer, now with tailored radiopacity. These compounds comprise an image contrast additive at specified levels, providing a broad contrast range for optimal visualization with x-ray, CT and MRI imaging modalities.
PEEK-OPTIMA image contrast grades are safe, biocompatible materials intended for implantable medical and pharmaceutical devices and applications requiring blood, bone or tissue contact of more than 30 days.
These compounds provide a unique combination of features and benefits, including:
- Tailored radiopacity allows implant visibility to be optimized
- PEEK-OPTIMA polymer provides a superior combination of strength, stiffness and toughness, even after sterilization
- Biocompatibility ensures safe, long term implantation
- Processing methods allow broad design and manufacturing flexibility
- US FDA Drug and Device Master files can assist with regulatory requirements
Unlike metals, PEEK-OPTIMA image contrast grades provide the possibility of tailoring the visibility of an implant to suit a particular application. It is therefore possible to achieve an appropriate balance of implant, bone and tissue visualization without artifacts or scatter.
Available in a range of viscosities (standard, medium and low), PEEK-OPTIMA image contrast grades can be processed by conventional methods, including injection molding and extrusion, and can be machined, allowing medical device manufacturers broad design and manufacturing flexibility.
Extensive testing of PEEK-OPTIMA compounds to ISO 10993 standards demonstrated no evidence of cytotoxicity, systemic toxicity or irritation. Results have been lodged with the US FDA and can reduce the time and expense of the approval process. 单位: 公制 | 英制

聚醚醚酮的物性说明；
(PEEK)树脂是一种性能优异的特种工程塑料，与其他特种工程塑料相比具有
诸多显著优势，耐高温、机械性能优异、自润滑性好、耐化学品腐蚀、阻燃、耐剥离性、
特点
耐辐照性、绝缘性稳定、耐水解和易加工等.
应用
在航空航天、汽车制造、电子电气、医疗和食品加工等领域得到广泛应用。
性能
优异应用广PEEK树脂最早在航空航天领域获得应用，替代铝和其他金属材料制
造各种飞机零部件。汽车工业中由于PEEK树脂具有良好的耐摩擦性能和机械性能，作为
制造发动机内罩的原材料，用其制造的轴承、垫片、密封件、离合器齿环等各种零部件在
汽车的传动、刹车和空调系统中被广泛采用。
PEEK树脂是理想的电绝缘体，在高温、高压和高湿度等恶劣的工作条件下，仍能保
持良好的电绝缘性能，因此电子信息领域逐渐成为PEEK树脂第二大应用领域，制造输送
超纯水的管道、阀门和泵，在半导体工业中，常用来制造晶圆承载器、电子绝缘膜片以及
各种连接器件。作为一种半结晶的工程塑料，PEEK不溶于浓硫酸外的几乎所有溶剂，因
而常用来制作压缩机阀片、活塞环、密封件和各种化工用泵体、阀门部件。
PEEK树脂还可在134℃下经受多达3000次的循环高压灭菌，这一特性使其可用于生
产灭菌要求高、需反复使用的手术和牙科设备。PEEK不仅具有质量轻、无毒、耐腐蚀等
优点，还是目前与人体骨骼最接近的材料，可与肌体有机结合，所以用PEEK树脂代替金
属制造人体骨骼是其在医疗领域的又一重要应用。国内生产发展快PEEK树脂是20世纪70
年代末由英国原ICI公司开发的，自问世以来，一直被作为一种重要的战略性国防军工材
料，许多国家均限制出口。
