PVC SG-5 Type Resin - Ideal for High-Durability PVC Products
Material Characteristics
PVC resin is a white powdered polymer synthesized through vinyl chloride monomer polymerization. Featuring uniform particle morphology (D50: 120-150 μm) and 92%+ whiteness index (ASTM E313), it delivers exceptional batch-to-batch consistency. Key attributes include:
- Processability: Optimized particle porosity (0.25-0.35 cm³/g) ensures rapid plasticizer absorption (≤15 min to full gelation)
- Thermal Stability: Initial decomposition temperature ≥180°C (TGA, 10°C/min in N₂)
- Electrical Properties: Volume resistivity >1×10¹³ Ω·cm (IEC 60093)
Advanced Manufacturing Process
Utilizing China's proprietary suspension polymerization technology, our production system integrates:
- Reactor Design: 80m³ vertical reactors with dual helical impellers for precise temperature control (±0.5°C)
- Particle Engineering: Multi-stage DCS-controlled drying achieves ≤0.3% moisture content
- Quality Assurance: Online FTIR monitoring ensures K-value consistency (65±1 for SG5 grade)
