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. Water was used as blowing agent. The rate of forming was increased by increasing catalyst and water content. On … Continue reading

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 by spectroscopy. Results showed that with the inclusion of DDSQ, the hydrophobicity of … Continue reading

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 reduce the fatigue. Polyurethane … Continue reading

New Castor Oil Segmented Thermoplastic Polyurethane with Controlled Mechanical Properties

Researchers from Finland have found a method to produce novel castor oil segmented thermoplastic polyurethanes which have controlled mechanical properties. Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. TPU … Continue reading

New Method for Production of Castor Oil Polyurethane

Recent study shows that a two-step mediation of castor oil could overcome the problem of polyaddition threshold of castor oil during polyurethane formation. The study has been conducted by scientists from India who have found that the mediation facilitates formation … Continue reading

Novel Bio-Based Polyols for Flame Retardant Polyurethane Sealants

A sealant is an elastomeric material that allows for 25% to 50% movement. They are used to level, fill gaps, seal holes and provide bonding and protection. Sealants are made by using either silicone or polyurethane. Polyurethane sealants are formed … Continue reading

Pure Polyurethane and Castor Oil Based Polyurethane: Synthesis and Characterization

Scientists from Malaysia performed an experiment to compare the physico-chemical properties of high performance polyurethane prepared using pure poly propylene glycol (PPG) and that prepared from PPG and castor oil. Characterization studies indicated the presence of large -CH stretching in … Continue reading

Synthesis and Characterization of Castor Oil Based Hybrid Polymers and Their Polyurethane-Urea/Silica Coatings

Scientists performed an experiment to synthesize castor oil based hybrid polymers and their polyurethane urea-silica coatings. New acrylated alkoxysilane castor oil (AASCO) with hydrolysable –Si–OCH3 was synthesized from CO, maleic anhydride and 3-(Trimethoxysilyl) propyl methacrylate via free radical copolymerization method. … Continue reading
