Biobased materials

Renewable raw materials represent a strategic opportunity both for the environment and for Arkema’s development. Building on its expertise in castor oil chemistry, the Group develops biobased products and materials derived from plants for wide-ranging markets (footwear, eyewear, cell phones, automotive parts, etc.).   

Biobased polymers and resins

Arkema offers a large number of biobased solutions, in particular derived from castor oil.

Rilsan® PA 11

For the last 70 years, Rilsan® polyamide 11 (or PA11) has been widely respected as a high performance resin for demanding applications. Processed from castor oil, this polymer is 100% biobased. For over ten years, Arkema has been expanding its range of long-chain polyamides to meet market demand, and offers technical bioplastics including:

  • Rilsan® HT range of flexible polyphthalamide (PPA) polymers which combine flexibility with outstanding high temperature performance in a wide range of applications including the replacement of metal/rubber combinations. This extreme product has now been widely adopted by the automotive industry.
  • Rilsan® Clear Rnew a transparent, lightweight and easy-to-process polyamide, perfectly suited to the eyewear market in particular.

Pebax® Rnew

Pebax® Rnew polyether block amide is a thermoplastic elastomer that is partly plant-based, extremely tough and demonstrates enduring elasticity even at very low temperature. It is extensively used in the manufacturing of ski boots and sports shoes (both cleated and non-cleated).

Platamid® copolyamides

As specialty thermoplastics, Platamid® copolyamides are used to manufacture hot melt adhesives for fusing textiles intended for clothing and industrial applications.

Altuglas® Rnew

Altuglas® Rnew transparent PMMA resins include biopolymers 100% produced from plant sugar. The fluidity of these technical alloys means they can be processed at low temperature and therefore benefit from a smaller carbon footprint. Applications of Altuglas® Rnew include electronics, consumer goods, optics and automotive.

Substances and additives

Biobased additives used in industrial and automotive lubricants.


The Sarbio® range marketed by Sartomer, an Arkema subsidiary, offers a wide range of acrylate and methacrylate monomers and oligomers, comprising, depending on the grades, 10 to 80% of renewable raw materials. These bioproducts are used in the formulation of varnishes, inks and coatings as well as adhesives.

Cecabase RT®

Used for the manufacture of warm bitumen mix, Cecabase RT® surfactant additives are synthesised from at least 50% vegetable oil. They help reduce dust emissions, lower the temperature at which the asphalt is laid, and so cut down energy consumption by up to 30% during road construction work.


Products from the Oleris® range are 100% of plant origin (castor oil). They have a very high purity (95 to 99%), contain no MGOs, are biodegradable, and comply with regulations. Finally, they are used for the synthesis of fragrances, aromas and cosmetics, as well as industrial lubricants and plasticisers.

VPS® et esterols sulfurisés

Derived from plant-based chemistry, VPS® sulfur-based additives from Arkema’s Thiochemicals business are used in particular in technical fluids for metalwork and in industrial and automotive lubricants.
