Plasticizers are non-volatile organic substances and the most common additives used in the plastics industry. It helps to improve flexibility, extensibility, and processability when incorporated into a plastic or elastomer. Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature, the melting temperature, and the elastic modulus of the finished product without altering the chemical character of the plasticized material. Plasticizers are majorly classified based on their chemical composition.
