Description
Product Introduction: PVC S6532
Suspension Polyvinyl Chloride (Suspension PVC – S6532)
Manufacturer: Arvand Petrochemical Company
PVC S6532 is a high-porosity, high bulk density suspension-type PVC polymer, specifically designed for the extrusion of rigid parts such as profiles, sheets, and pipes. This grade, classified as S65, offers rapid melting and high-rate extrusion capabilities.
Key Features of PVC S6532:
✅ Suitable porosity for plasticizer absorption (19–25%)
✅ High bulk density (550–610 g/L)
✅ Uniform particle size distribution (over 95% < 63 microns)
✅ Very low levels of volatiles and residual monomer (VCM ≤ 1 ppm)
✅ Very few dark particles and visual defects (≤ 20 fish eyes per 25 cm²)
✅ Fast and uniform extrusion with standard additives
Recommended Applications:
✅ Rigid PVC profiles (e.g., doors and windows)
✅ Rigid PVC sheets
✅ Extrusion of industrial pipes and ducts
This product blends easily with conventional additives and delivers excellent performance in extrusion processes.
