PVC SG3 is a type of suspension-grade PVC resin characterized by a high K-value, typically in the range of 72–71, indicating a higher molecular weight compared to other grades. This makes SG3 an excellent choice for applications where higher flexibility, tensile strength, and elongation are required. Its fine particle size and high viscosity contribute to improved film-forming properties, making SG3 particularly well-suited for products such as thin films, flexible hoses, synthetic leather, and various coatings.
