Insights

POK polyketone selection logic, injection and extrusion windows, failure analysis and metal-replacement criteria — written for engineers, not for search engines.

8 articles Ask with your case

Engineering notes from the Juhong technical team: which grade fits which service condition, how to set the injection and extrusion windows, how to work backwards from a field failure, and when POK is the right substitute for PA66 or POM.

If your part is stuck on hydrolysis resistance, fatigue life, dimensional drift or metal replacement, start with the article closest to your case — or send us the operating conditions and we will answer with a specific grade plus its TDS.
