A typical PVC Resin SG5 Technical Data Sheet (TDS) describes the product as a white powder with an SG5 K-value of approximately 66-68, indicating a specific molecular weight range used for applications like pipes, fittings, profiles, and injection molding. Key specifications include a volatile matter content of around 0.3-0.4% max, a bulk density of about 0.53-0.54 g/ml, and impurity particle limits, though exact figures can vary slightly between manufacturers. Typical Specifications
- Appearance: White powder
- K Value: 66-68 (This value indicates the degree of polymerization and is related to the molecular weight)
- Viscosity (ml/g): Approximately 107-118
- Average Polymerization: Around 1030-1100
- Volatile Matter: 0.3% - 0.4% (maximum)
- Bulk Density (g/ml): 0.48 - 0.54 g/ml (minimum or range)
- Impurity Particle Number: Low, often around 16-30 (particles/100cm²)
- Residual VCM (Vinyl Chloride Monomer): Low, around 1 µg/g (maximum)
Common UsesPVC Resin SG5 is a suspension-grade resin that is quickly absorbed by plasticizers and is suitable for manufacturing: Pipes and pipe fittings, Profiles, Calendering products, Injection molding products, and Hard products like panels and some rigid parts.
