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)
Target Applications
| Industry | Products | Technical Requirements Met |
|---|---|---|
| Construction | Pressure pipes (Class 1.25MPa) | Hydrostatic stability (20°C/100h, ISO 1167) |
| Window profiles | Weathering resistance (ΔE<2 after 6,000h QUV) | |
| Packaging | Transparent blister packs | FDA 21 CFR 177.1950 compliance |
| Pharmaceutical foils | Low extractables (<50ppm total migration) | |
| Automotive | Underbody components | Salt spray resistance (1,000h ASTM B117) |
| Electronics | Cable conduits | Flame retardancy (V-0 rating, UL94) |
Processing Guidelines
Extrusion Parameters (Single-Screw, L/D=25):
- Zone 1-3 temps: 160°C / 170°C / 180°C
- Die temp: 185°C ±3°C
- Screw speed: 25-40 rpm
- Vacuum venting: ≥0.08 MPa
Stabilizer Recommendations:
- Calcium-zinc systems: 2.5-3.5 phr for non-toxic applications
- Lead-based systems: 1.8-2.2 phr for cost-sensitive profiles
Regulatory Compliance
- Food Contact: Meets EU 10/2011, FDA 21 CFR 177.1950
- Environmental: REACH registered, RoHS 3 compliant
- Safety: SDS available per GHS Rev.9 standards
Packaging & Storage
- Units: 25.00±0.15 kg PP-woven bags with UV-blocking inner liner
- Palletization: 40 bags/pallet (1,000 kg) with corner protectors
- Shelf Life: 18 months from production in dry conditions (<40% RH)
- Handling: Forklift pockets reinforced for 3x stacking
Technical Support
Our polymer engineers provide:
- Process Optimization: Scientific molding simulations to reduce cycle times
- Troubleshooting: On-site assistance for die lines/flow marks resolution
- Customization: K-value adjustments (±2 units) for specific flow demands
