Castor plant
A shrub which grows in tropical regions; its seed is the source of castor oil, which has a wide variety of uses, including the manufacture of Rilsan® polyamide 11.
CO2
Carbon dioxide is a greenhouse gas produced during the combustion of organic compounds and the breathing of living organisms and plants. The photosynthesis process which contributes to plant growth consumes much more CO2 than is produced from their breathing.
Elastomer
A polymer whose flexible structure accommodates significant reversible deformation.
Fossil resources
A fossil resource is a depletable or non-renewable resource whose creation requires far longer than human lifespan. Crude oil, natural gas and coal are fossil resources.
Pebax® Rnew
Pebax® Rnew is a range of polyether block amide thermoplastic elastomers in which the polyamide component is directly derived from castor oil chemistry.
Pierre Potier
A pharmacist and a chemist (1934 – 2006), Pierre Potier was inter alia Director of the Institut de chimie des substances naturelles [Institute for the Chemistry of Natural Substances], a Professor at the Muséum national d’histoire naturelle [National Natural History Museum], and a member of the Académie nationale de pharmacie [National Pharmaceutical Academy] and of the Académie des sciences [Academy of Science].
Polyamide
A polyamide is a polymer obtained by the reaction of an amine and an acid characterized by the amide function. Nylons are polyamides whose structure varies on the basis of the number of carbon atoms of their monomer.
Polymer
A polymer is a macromolecule consisting of a chain of repeating identical links or monomers. Plastics are polymers.
Renewable resources
A resource is renewable when its production is conceivable within a very short period of time (e.g. plants), or when it does not become depleted through consumption (e.g. solar energy).
Rilsan® 11
Rilsan® 11 is a polyamide of exclusively vegetable origin, directly derived from castor oil chemistry, whose monomer comprises 11 carbon atoms.
Thermoplastic elastomer
A thermoplastic elastomer is a block copolymer (combination of two polymers) with one rigid mononer and one flexible monomer.
