Arkema to Invest in New Bio-based Nylon Production

Arkema has planned to invest 300 million euros for expansion of its bio sourced nylon 11 production in Asia. By establishing this plant, the company would increase the global production of bio sourced nylon 11 by 50%.Logotype_arkema

The new plant, which will produce both the amino 11 monomer and its polymer, is expected to come on stream in late 2021. The products to be produced would find applications in electronics, 3D printing and automotive industries.

Durable Commercial Flooring Made From Natural Materials

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.mats inc

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 to grow at a CAGR of 6.75%

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.castor oil polyurethane

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.

New Bio-based Building Block for the Chemical Industry

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.

Novel One Shot Method for Synthesis of Castor Oil Polyurethane Foam

Researchers from India prepared castor oil polyurethane from pre-polymer oftoluene diisocyanate (TDI) and castor oil with dibutyl tin dilaurate (DBTDL) catalyst. Homepagecarroussel-research1Water was used as blowing agent. The rate of forming was increased by increasing catalyst and water content. On other hand the cell size of the PU decreased with increasing amount of the catalyst and water content.

Characterization studies were performed to analyse the properties of synthesized foam.

New Castor Oil Based Polyurethanes Reinforced With Double-Decker Silsesquioxane

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 castor oil polyurethaneby spectroscopy.

Results showed that with the inclusion of DDSQ, the hydrophobicity of the hybrid material was significantly improved.

Chemical Modification of Cellulose Fibres Using Castor Oil

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.castor oil polyurethane

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.

Modification of Asphalt using Castor Oil Based Polyurethane

Scientists from India performed an experiment where asphalt which is commonly used for road pavement was modified using castor oil based polyurethane to improve the properties of asphalt such as resistance to permanent deformation and to refined_bitumenreduce the fatigue.

Polyurethane pre-polymer (PUP) was prepared by using castor oil and toluene diisocyanate (TDI). Asphalt modification was done using castor oil (C.O.) and PUP. Results showed that polymer modified asphalt showed improvement in properties such as hardness and softening point thereby making the pavement application smooth.
