Layered double hydroxides as thermal stabilizers for Poly(vinyl chloride): A review

Poly(vinyl chloride) (PVC), an important thermoplastic polymer widely-used in various fields, requires the use of thermal stabilizers to enhance its stability during processing and practical applications because poor stability. Layered double hydroxides (LDHs), two-dimensional anionic layered versatile filler, are widely considered be one kind high-efficient environment-friendly PVC stabilizers. Interestingly, it is expected gradually replace traditional toxic such as lead salts. The recent development LDH resins here reviewed from four relevant aspects: - stabilization mechanism provided by LDHs, − chemical composition metal layers interlayer guests, dispersion state composites. review provides a current picture help choice manufacturing high-performance
