Arkema group celebrated 70th anniversary of its flagship product Rilsan nylon 11 series of high performance polymers. Rilsan PA 11 is sourced from castor oil and is a bio-based member of the nylon family.
Nylon 11 made its market debut under the brand name Rilsan in 1949 and was taken up by automaker Citroën in 1950s as new plastic for fuel lines. Arkema produces the material at its sites in Serquigny, France, Birdsboro, Pa., and Zhengjiagang, China.
In 2014, Mats Inc. partnered with Windmöller Flooring Products to deliver an entirely new class of product. That collection is wineo® PURline, an innovative collection of botanol flooring produced with 90% rapidly renewable and natural raw materials.
Wineo PURline is botanol, a plant-based material that’s both odorless and emission-free. Its ingredients—canola oil from rappa seed, castor oil from castor seed, and chalk—are molecularly transformed to create an eco-friendly polyurethane that serves as a durable nonporous floor covering.
Global bio-based polyurethane market is expected to grow at a CAGR of 6.75% during 2016-2020. Among many natural oils, castor oil is primarily used for producing natural oil polyols due to the availability of ready hydroxyl group unlike other oils that require the introduction of hydroxyl group by other procedures.
Apart from adipic acid, bio-based succinic acid and 1,4 butanediol can be combined with the required isocyanates to produce polyurethanes with up to 70% bio content.
Bioplastics marketer Bio-Fed has launched its M-VERA ECS series made from castor. The company, a subsidiary of Akro has turned to bio oil from castor seeds.
This decision has been made owing to fluctuations in oil price, to reduce energy consumption and improve their carbon footprint.
Unlike the previous products in M-Vera line, ECS products are partially biobased but not biodegradable.
Mitsui Chemicals & SKC Polyurethanes Co. Ltd. (MCNS) a 50:50 joint venture of Japan’s Mitsui Chemicals and South Korea’s SKC will establish a polyurethane system house, MCNS Polyurethanes India Pvt Ltd, in Andhra Pradesh with an initial investment of $ 7.3 million (about Rs 49 crore).
The facility to be located at Nellore district will manufacture polyurethane system products and have a capacity of 13,000 tonnes per annum.
Biopolyamides market is estimated to grow well in the coming years till 2025. Undecanoic acid and sebacic acid derived from castor oil are among the most dominant raw materials used in the production of bio based polyamide. Owing to the eco logical benefits, bio based polyamides are gaining acceptance and are anticipated to be the fastest growing product segment during the coming years.
Automotives is the largest application segment for polyamide and the trend is expected to continue in the near future. Demand for polyamide in packaging applications is expected to outdo other application segments in terms of growth rate during the coming years.
Scientists from Columbia performed an experiment to develop a kinetic model for high CO2 pressure carbonation of epoxidized castor oil which can be used for production of thermoset polymers and non-isocyanate polyurethanes.
Results showed that because of the polyfunctional character of the product, it could find applications as a monomer and as a synthetic building block for other bio-based chemicals.
Scientists from China synthesized hybrid polyurethanes with double-decker silsesquioxane (DDSQ) using castor oil and isophorone diisocyanate (IPDI) as feedstock. Double-decker octaphenyl silsesquioxanetetraol (DDSQ) was prepared and characterized by spectroscopy.
Results showed that with the inclusion of DDSQ, the hydrophobicity of the hybrid material was significantly improved.
Cellulose fibre reinforced composites are considered suitable alternative to plastic products due to the environmental problems caused by the latter. However, pure cellulose fibres have a high hydrophilicity. Moreover, the polar character of these fibres causes their low compatibility with partially or totally hydrophobic polymer matrices.
Owing to the poor wettability and adsorbability towards polymers, the surface modification of the fibres surface is essential, in order to improve the fiber/polymer compatibility and their interfacial adhesion. Hence researchers from France conducted a study to improve the properties of cellulose fibres by modifying the cellulose fibres with trialkoxysilane from castor oil.
Characteristic studies were carried out for the modified cellulose-castor oil polyurethane composites. Results showed that compared with the crude cellulose fibres, the organosilane treatment reduced the hydrophilicity of the natural fibres and increased the fiber/matrix compatibility.
Scientists from India performed esterification of furfuryl alcohol and castor oil fatty acid at 3:1 molar ratio, by immobilized Candida antarctica Lipase B in a solvent free system. A maximum yield of ester was obtained. Performance of the FA-COFA ester plasticized Ethyl Cellulose (EC) films were evaluated by certain characteristic studies.
Results showed that the furfuryl alcohol-castor oil fatty acid ester with significant plasticizing property at a certain concentration could act as a substitute for traditional plasticizer dibutyl phthalate.
