Arkema's PA11 biobased polyamide is leading the green revolution in the materials industry. Sourced from castor oil, this 100% renewable material perfectly combines excellent mechanical properties with environmental benefits, making it an ideal choice for high-end applications in automotive, electronics, 3D printing, and sporting goods.

Nature's Source, Beauty of Technology
PA11 uses sustainably cultivated castor oil as its raw material, reducing the carbon footprint by 40% compared to traditional petroleum-based nylons. Arkema has established a global production network in France, China, and the United States, ensuring the stability of the material supply chain. Its unique molecular structure provides PA11 with excellent impact resistance (notched impact strength up to 45 kJ/m2) and low water absorption (saturation water absorption rate of only 1.9%), maintaining dimensional stability even in humid environments.

Green Solution for Automotive Lightweighting
As an industry standard for fuel lines and brake systems, PA11 holds a significant position in the automotive sector due to its excellent oil resistance (compliant with ISO 6722) and vibration fatigue resistance. Its broad operating temperature range of -40°C to 130°C makes it particularly suitable for battery components and fluid management systems in new energy vehicles. Being 50% lighter than metal, it offers an environmentally friendly solution for vehicle weight reduction and efficiency improvement.
