  • Publication number: 20130303640
    Abstract: The present invention relates to a vinyl chloride resin composition containing diethylhexylcyclohexane as a plasticizer. Diethylhexylcyclohexane may replace controversial phthalate based plasticizers to prevent environmental contamination and have significantly low initial viscosity and low-temperature viscosity and a remarkably low low-temperature viscosity with the passage of time as compared to the existing phthalate based plasticizers and dioctyl terephthalate, which is a non-phthalate based plasticizer, such that the vinyl chloride resin composition containing the diethylhexylcyclohexane plasticizer may have excellent workability and generate less volatile organic compounds, thereby making it possible to apply this composition to develop eco-friendly products.
