Potential of Palm Oil as a Renewable Material for Radiation Curable Coating
Cheong Mei Yee* and Zafarizal Aldrin Azizul Hasan*Research on bio-based polymers and resins in industrial applications has seen some progress as well as the products facing competition with their petroleum-based counterparts. The demand for bio-based polymers and resins is due to their property of environmental friendliness as they are made from renewable resources (Ashraf et al., 2015). Additionally, human health is compromised when using traditional coatings which utilise high molecular weight polymers that release volatile and toxic solvents when crosslinked with heat, or when coalesced dry, resulting in serious hazards to human health. The hazardous air pollutants and volatile organic compounds (VOCs) released into the atmosphere during manufacture and application of coating materials lead to environment contamination. Environmental regulations and government legislations towards zero waste generation during the development as well as application of coating materials have been the dominant driving force in advances in bio-based polymers. Due to their abundance, palm triglycerides provide a renewable alternative to petroleum-based coating. Palm oil is the leading vegetable oil in terms of production volume as the oil palm produces between eight and 10 times more oil per hectare per year compared with annual oilseeds such as rapeseed or soyabean (Basiron, 2007). In fact, palm oil accounted for 32.0% of the global oils and fats output in 2012 (Sime Darby, 2014) and 30.1% in 2016 (Mielke, 2016).
