High temperature resistance & design flexibility without metal in automotive air intake and cooling & heating systems pipes

Sustaining high service temperatures exceeding 170°C is often difficult without metal in turbo charged engines. However, new alternatives are needed in order to gain some design freedom, especially for a use around engines.

New solutions based on Polyamide 66 specifically designed for blow molding applications can advantageously replace metal since they allow higher part complexity, lower weight and ultimately, system cost reduction.

Do you need advice on how to switch from metal to PA66? If you still haven't found the right material that will allow you to replace metal for high temperature resistance, don't hesitate anymore! Our experts await your needs: they can evaluate new solutions with you, for your specific application.   Reach the right expert to speed up your projects:

TECHNYL® can substitute metal until 135°C in Coolant system pipes

TECHNYL® passes the most stringent requirements, such as: Service temperature from 90 to 135 °C Cooling liquid ageing test (typical 1000h at 120°C) Pulsating pressure test on parts at service temperature Internal surface finish to reduce pressure drop Fatigue resistance at service temperature

Test TECHNYL®'s efficiency in realistic conditions up to 200°C in air intake system

We can help you test the component in realistic conditions to verify the validity of TECHNYL® solution in your specific system. You can simulate the air flow, associated with the pressure pulse on pipes thanks a strong equipment capability. Internal air temperature up to 200°C can be achieved for the most demanding applications.
