What are the main benefits of using PEEK in cables

 

Of all the materials CITCABLE use PEEK is one of the most impressive all-round high-performance insulations. Its fire, smoke and chemical resistance properties compare favourably with the likes of ETFE and PTFE, as does its properties as a thin-wall material. 

Where PEEK has the edge is that it’s a completely halogen-free and flame-retardant material that comes with unsurpassed radiation resistance. It’s also a high-temperature material that can continue to operate safely in temperatures up to 260°C. 

There are two ways to process PEEK, each with different properties: amorphous PEEK gives the material more flexibility and is suitable for temperatures below 140°C, while crystalline PEEK increases its hardness and temperature range to up to 190°C for at least 20,000 hours.

Finally, it has a long product lifespan of 60+ years at continuous temperatures up to 90°C. 
 

What is PEEK?

Polyether ether ketone (PEEK) is a halogen-free thermoplastic polymer material, or a plastic that can be melted and shaped, and then rehardens once cooled. It’s been around since the early 90s, and is used in many industries for applications where you need a mechanically tough material that’s resilient to radiation, chemicals, abrasion and extreme heat.

Our PEEK cables

  we’ve been working with PEEK for decades, and it’s one of our main areas of expertise. It’s often a core material in our custom cable solutions, but it can also be found in our standard products, including:
   
Nuclear Power cable
