The 2018-B multi-component nanoparticle non-metallic powder is used as a polymerization carrier, and oligomers and thermoplastic elastomers are incorporated to form a new type of macromolecular high-activity alloy material through special polymerization process and functional composite coating modification technology. It can promote the gelation and plasticization effect of PVC, the plasticization is fast during processing, the viscosity increases, the thermal strength increases, the uniform dispersion improves the melt fluidity, the plasticization degree is good, the surface gloss is good, no precipitation, and weather resistance it is good.
