APPLICATIONS
Product Applications
PVC Resin SG-3 is characterized by its high degree of polymerization and exceptional plasticizer compatibility. It is primarily employed in the flexible product sector, yielding finished goods with superior mechanical strength, flexibility, and surface finish. It serves as an ideal raw material for manufacturing high-performance wire and cable sheathing, industrial and domestic films, flexible hoses, and injection-molded articles (e.g., footwear, toys).
