PVC S57 is a high-quality, free-flowing vinyl chloride homopolymer resin with a low molecular weight, produced through suspension polymerization. This grade of PVC, with a K value of 56.1-57.8, exhibits low porosity and very high bulk density, making it ideal for rigid applications and high machine throughput. With a viscosity range of 0.665-0.72 and a bulk density between 0.5-0.62, PVC S57 is well-suited for use as an additive polymer in specific applications. Known for its thermoplastic properties, it contains approximately 57% chlorine by weight and is widely used in various forming methods. It is supplied in powder form and is produced by Abadan and Ghadir Petrochemical Company under HS code 39041090. .
PVC S57 is a versatile resin extensively used across various industries due to its excellent properties. In injection molding, it is ideal for producing rigid PVC parts and pipe fittings, where its high bulk density and low porosity are particularly beneficial. For sheet extrusion, PVC S57 is utilized in the manufacturing of rigid films and both compact and foamed rigid sheets.
In calendaring processes, this grade is employed for creating rigid films and sheets. Additionally, it is used in the extrusion of flexible sections and hoses. PVC S57 is commonly applied in electronic and electrical equipment, special packaging, and most notably, in the production of PVC fittings, where its characteristics ensure durability and precision.
