Recent Advancement in plant-oil derived polyol based polyurethane foam for future perspective: A review Indrajeet Singh*, Sushanta K. Samal, Smita Mohanty, Sanjay K. Nayak School for Advanced Research in Polymers (SARP) - LARPM Central Institute of Plastics Engineering & Technology (CIPET) - IPT, B/25, CNI Complex, Patia, Bhubaneswar-751024, Odisha, India, Fax: +91 - 674- 2743863; Tel: +91 - 674- 2742852 *Corresponding Author E - mail: indrajeetmaithil@gmail.com Abstract Polyurethane foams (PUF) are the widely used material because of its wide range of application, particularly thermal and sound insulation, mattress, furniture, construction, cushioning, packaging, transportation of goods, etc. Recently, commercial PUF products fabricated from plant oil- based polyols have gained increasing popularity among society, because of their low cost and eco-friendly nature in comparison to petroleum-based PUF. To date, insufficient reviews have been reported in the area of modification of plant oils for synthesizing polyol for foam synthesis. Due to abundant availability, low-cost and renewable nature of plant oils, they are being used as precursors for modern polyurethane industry use. There is a need for versatile and economical methods for conversion of plant oils such as castor oil and soybean oil into useful polyols for industry use. This review focuses on an overview of the most recent advance methods for conversion of plant oils into polyol and further utilization it for commercial PUF products. From the last decade, many researches showed that plant polyol derived PUF can compete with conventional polyurethane foams. Keywords: eco-friendly, plant-oil, Polyurethane foams, renewable, castor oil, soybean oil. Practical applications : Practical application of the plant oil based polyurethane foams are thermal insulation, sound insulation, packaging and waste water treatment. 1 Introduction Non-renewable resources such as fossil fuels, coal, etc., are utilized to prepare the majority of organic compounds for modern chemical society. In order to procure chemicals from these resources, a huge amount of carbon dioxide is released during processing into the open environment that has steered the global warming issue. On the other hand, limited availability and non-renewable nature of fossil feedstock lead to an increase in the price of petroleum-derived
