The polyurethanes (PUs) foam were made from vegetable oil; a soybean based polyol. The foams were categorized into flexible and semi rigid. This research is manufacturally designed polyurethane foams by a process requiring the reaction of mixture of 2, 4- and 2, 6-Toluene di Isocyanate isomers, soy polyol in the presence of other ingredients. The objective of this work was to functionalized soy-polyol using phosporic acid catalyst and chain extender, study their collaborative reaction in producing ultimate property of PU foam. Correlates the foam morphology images in accordance to mechanical properties of foams. Source

Polyurethane foam are obtained by using soy-polyols, TDI: MDI (80:20), and surfactant. Soy-polyol is made using a low molecular weight of alcohol; methanol and ethylene glycol. The responses of ethylene glycol and methanol to silicon surfactant has produces a unique polyurethane. With the ability minimized water absorbency. The goals of this study is to determine the optimal conditions of using of methanol and ethylene glycol in soy-polyol synthesis as based substance for polyurethane formula. From this work we found a relation between foam reduction absorption to its morphology and the voids occured, the shape of the surface of the foam, and the curing time of foaming. Optimal conditions of polyol synthesis is found at the ratio of epoxide/methanol is 1: 6 (mol/mol), and epoxide/Ethylene Glycol 1: 3 (mol/mol). © Research India Publications. Source

The tryglyceride of vegetable oils should have at least one of unsaturated fatty acid moiety to be modified with sulfur acid catalyst in peracetic acid co-reagent, to be introduced to the desired hydroxyl functional groups in soy-polyol structure. A series of screening reactions have indicated the ratio of acetic/peroxide acid 1:7.25 (mol/mol) with temperature 60°C is the best condition for soy-epoxide to be up-scaled to 10 and 20 folds from initials. A 90 minutes is the best lenght of reaction for polyol to be synthesized where the oxirane value and acid value occured are quite preferable for the proceed reactions. The recommended reactor volume is multiple of 400 mL. There are tendency of increasing the acid number if the volume enlarged 10 times, so it needs repeated netralizations. New methods are need for the cost efficient. © 2006-2015 Asian Research Publishing Network (ARPN). Source

The growing interest in reducing environmental impact of polymers or composites due to increased awareness to eco-friendliness. The finite petroleum resources has impacted to decreased pressures for the dependence onpetroleum products which has increased in maximizing the use of renewables material. Bamboo are used for principal constituent of reinforced composite which incorporated to epoxide based resin from vegetables oil; canola, soybean, corn, and sunflower. The products obtained resulted the promising composites material for green environmental and also acceptable mechanical property. © Research India Publications. Source

Polyurethane foams (PUF) has been prepared from vegetable; soybean based polyols. They were characterized into flexible and semi rigid polyurethane foam. This work is directed to production of flexible polyurethane foams by a process involving the reaction of mixture of 2,4- and 2,6-Toluene di Isocyanate isomers, with portion of to blends of soy polyols with petroleum polyol in the presence of other ingredients such as blowing agents, silicone surfactants and accelerating agents. Additon of chain extender improves the property then further decreases the properties on further addition of the same. The objective of this work was to study the effect of chain extender and role of phosphoric acid catalyst to the final properties and correlate the morphology image with mechanical properties of these foams.
