PEEK modified material as medical skull repair material

When it comes to special engineering plastics, many people will come up with polyphenylene sulfide polyether PPS, polyarylate PAR, liquid crystal polymer LCP, polyether ether ketone PEEK and so on. Let's talk about modified poly Some performance characteristics and applications of ether ether ketone PEEK materials.

   In the industry, modified polyetheretherketone PEEK is a crystalline high-performance special engineering plastic. It is also a new type of modified material explicitly proposed during the National Twelfth Five-Year Plan. It can be named by the country, that is, it has unique performance advantages. For example, it has superior dimensional stability characteristics because temperature and humidity have very little influence on the appearance of its finished product. More importantly, as a semi-crystalline engineering plastic, PEEK is not afraid of concentrated sulfuric acid, and other solutions are not much destructive to it.

   So what is PEEK modified materials and what are the performance characteristics?


As a special engineering plastic, LFT-G modified PEEK has high mechanical strength, high temperature resistance than PPS, impact resistance, flame retardancy, acid and alkali resistance, hydrolysis resistance, wear resistance, fatigue resistance, radiation resistance and other superior properties. So it is very suitable in some high-end areas. In addition, the modified PEEK material has a small injection molding shrinkage rate. Therefore, it is important to control the dimensional tolerance of the PEEK injection molded part for the relatively high dimensional requirements of the finished part. In comparison, the dimensional accuracy of the PEEK part is more general. The plastic is several grades higher.

Next, let's take a look at the application of modified PEEK. Can it be used as a skull repair material?

 First of all, the choice of materials for skull repair is very important. Can the modified PEEK material be used to repair the skull? Experts who used PEEK material for skull repair earlier showed that many years of experience found that PEEK material for skull repair not only has good mechanics. Performance, plasticity, chemical stability and biocompatibility, can withstand high temperature steam and irradiation disinfection, and radioactivity and magnetic resonance scanning will not produce artifacts, low density, light weight implants More comfortable, does not conduct heat, so it is a very suitable skull repair material!

  Because of the excellent comprehensive performance of LFT-G modified PEEK, the products are widely used in the automotive industry, electrical and electronic manufacturing, aerospace high-tech industry, medical and food processing. It has been used, and the field of application is constantly expanding. Moreover, domestic research on modified PEEK has become more important and will be better and better in the future.
