Arkema, a pioneer in ultra high performance thermoplastic materials for transportation
Temperature constraints
To be able to use thermoplastics in an extreme heat environment, Arkema has developed Rilsan® HT.This biosourced polyphthalamide (PPA) polyamide is flexible and can replace metal or rubber in several under-the-hood flexible pipe applications thanks to its resistance to high temperatures.
An automotive part made of Rilsan® HT resin is up to six times lighter than a metal part.
Durability and sturdiness constraints
To replace metal in cutting-edge sectors such as civil and military aeronautics, Arkema has developed the Kepstan® PEKK product range (polyether ketone ketone).This polymer of the extreme, while also lighter, features the same properties as metal in terms of abrasion and impact resistance as well as non-combustibility:
- 40% lighter than aluminium
- withstands more than 260°C
