  • Highly elastic polyvinyl chloride composition and products prepared using the same
    Publication number: 20070037929
    Abstract: A highly elastic polyvinyl chloride composition comprises polyvinyl chloride-rubber particles including rubber particles and secondary polyvinyl chloride particles formed by combination of primary polyvinyl chloride particles. In the polyvinyl chloride-rubber particles, pores between primary polyvinyl chloride particles that form secondary polyvinyl chloride particles are filled with rubber particles. A film manufactured using the polyvinyl chloride composition has high elasticity, and rubber particles contained in the film have high uniformity. In addition, by using cross-linked rubber particles, the polyvinyl chloride composition may show high elongation, large tensile strength, and excellent processability due to no increase in viscosity even when the content of plasticizer used is not increased during a film formation process.
