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)

‌Sustainability & Compliance‌

• ‌Recyclability‌: Compatible with mechanical recycling streams (5× regrind cycles with <15% property degradation)
• ‌Carbon Footprint‌: 2.8 kg CO₂/kg resin (cradle-to-gate, verified by PAS 2050 methodology)
• ‌Halogen-Free Options‌: Available with calcium-zinc stabilizers for RoHS 3/ELV directive compliance67

‌Market Differentiation‌

1. ‌Batch Consistency‌

   • Controlled particle size distribution (D50: 120–140 μm) via laser diffraction monitoring
   • ±2% viscosity deviation across production lots

2. ‌Technical Support‌

   • Customized formulation services for:
     • Anti-static grades (surface resistivity 10⁹–10¹² Ω/sq)
     • Transparent compounds (haze <5% at 2mm thickness)

3. ‌Supply Chain Reliability‌

   • 30,000 MT annual production capacity with JIT delivery networks
   • 72-hour emergency response for quality-related issues12

‌Operational Guidelines‌

• ‌Storage‌: 12-month shelf life in <30°C/<60% RH environments (original packaging)
• ‌Handling‌: Recommend using 80–100 mesh sieves during premixing to eliminate agglomerates
• ‌Safety‌: MSDS-certified NFPA 704 rating: Health 1, Flammability 1, Reactivity 0
