PVC-SG-5 Resin - Excellent Processability for Plastic Products
Product Overview
PVC-SG5 resin is a suspension-polymerized polyvinyl chloride formulation optimized for high-output extrusion and calendaring processes. With a controlled K-value range of 66-68 (ISO 1628-2), it achieves an exceptional balance between melt flow stability and mechanical strength, making it the preferred choice for manufacturers requiring precision in large-scale production.
Key Technical Advantages
-
Enhanced Processability
- Rapid fusion characteristics: Achieves full gelation within 90-120 seconds at 180°C (Brabender torque rheometer)
- Broad processing window: Stable viscosity retention across 170-190°C (±5% torque variation)
- Low plate-out tendency: <0.25% additive migration in prolonged runs
-
Mechanical Performance
- Tensile strength: ≥50 MPa (ASTM D638)
- Impact resistance: 8 kJ/m² (Charpy notched, ISO 179)
- Vicat softening point: 80°C (ISO 306, 10N load)
-
Material Consistency
- Particle size distribution: 100-150 μm (D50 laser diffraction)
- Porosity: 0.28-0.32 cm³/g (mercury intrusion porosimetry)
- Bulk density: 480-520 kg/m³ (ISO 60)
