If you’ve ever worked with vacuum systems, you know they usually need a bake-out before use. Think of bake-out as a deep clean: the whole chamber gets heated up — sometimes to 150°C, 200°C, or even hotter — to drive off any moisture and contaminants lurking on the surfaces. This process is critical to achieving a clean, high-quality vacuum environment.

But here’s the catch: not every cable protection sleeve can handle that kind of heat. Ordinary sleeves might warp, become brittle, or worse, start releasing particles themselves — which defeats the whole purpose!
This is where PEEK braided sleeves really shine. PEEK is a high-performance polymer that laughs in the face of heat — it can handle short bursts up to 260°C without breaking a sweat and stays stable even during long periods of high temperature. Plus, it doesn’t soak up water and then drip it back out during the bake-out, keeping your vacuum system clean and dry.
So what does this mean for you in real terms?
- Your vacuum chamber bakes out faster and achieves better vacuum levels because there’s less contamination floating around.
- The sleeves don’t degrade or crack under heat, so you save money and headaches on replacements and repairs.
- Your cables stay protected through the entire cleaning and chemical prep process, ensuring your system keeps running smoothly.
If you’re working in a lab with vacuum systems, semiconductor fabs, or any high-tech field where cleanliness and uptime matter, choosing PEEK braided sleeves means fewer shutdowns and more consistent results.
