- Technical Info
Thermal stabilizer additives increase thermal aging significantly. In operating temperatures over 80°C, it performs with a longer duration compared to other extrusion and cast polyamide types. Its continuous operating temperature increases by 15-30°C compared to Kestamid® and reaches the 125-140°C interval. Thanks to its short term operating temperature that reaches 185-200°C interval, it is used safely in many applications that require heat resistance. In addition to its thermal aging property, it has all other technical assets of Kestamid®. Special additives make it possible to maintain the other technical properties while increasing thermal performance. It is possible to produce its UV resistant type on request.
