2. PA-XTreme /High Temperature PA
New requirements and materials challenges
Automotive Industry trends:
•Engine downsizing
•Lower limits on CO₂ emission
•Longer vveehhiicclleess lliiffee ttiimmee
•Reduced under bonnet space
Polyamide Requirements:
•Higher temperature resistance
•Better properties retention after exposure to high
temperature
•Longer high temperature exposure time

3. PA-XTreme /High Temperature PA
The answer :
Radilon® XTreme : a big step forward in
performance at elevated temperatures
New range of PA products for temperature
continuous use until 220-230 °C in contact
with air
