Tianhu Polyvinyl Chloride PVC Resin SG-5 Premium Quality for Construction Materials
Developed by Wuhai Chemical Industry (Inner Mongolia, China), the Tianhu PVC Resin SG-5 represents a premium-grade polyvinyl chloride compound engineered for versatility across modern manufacturing sectors. This white powdered polymer, packaged in standardized 25kg woven bags with moisture-resistant liners, combines advanced processing characteristics with exceptional material performance, making it a cornerstone material in construction, packaging, and consumer goods industries16.
Technical Profile
The SG-5 formulation adheres to China's GB/T 5761-2018 standards for suspension-grade PVC resins, featuring:
- Molecular Weight: 60,000–80,000 g/mol (K-value 66–68)
- Bulk Density: 0.48–0.52 g/cm³ (optimized for pneumatic conveying systems)
- Porosity: 0.25–0.35 cm³/g (enhanced plasticizer absorption up to 35 phr)
- Volatile Content: ≤0.40% (ensuring low foaming during extrusion)
- Residual VCM: <1 ppm (meeting EU REACH Annex XVII compliance)
Certified under ISO 9001 and ISO 14001 protocols, the production process employs ethylene-based polymerization with microsuspension technology, achieving 99.8% monomer conversion rates23.
