Key Features & Advantages
Uniform Particle Structure
- Controlled Particle Size (100–150 μm): Ensures even dispersion during mixing and uniform melt flow in extrusion/calendaring processes.
- High Porosity (20–25%): Enhances plasticizer absorption for flexible applications like synthetic leather and wire coatings.
- Low Fish-Eye Content (≤10 pcs/100 cm²): Critical for achieving smooth surfaces in transparent films and high-gloss sheets.
Superior Processing Performance
- Broad Processing Window (160–200°C): Adaptable to diverse equipment, from twin-screw extruders to high-speed calendaring lines.
- Fast Gelation Time: Reduces cycle times in injection molding and improves productivity in continuous sheet production.
- Low Volatile Content (≤0.3%): Minimizes odor and emissions during processing, ensuring workplace safety.
Exceptional Mechanical & Chemical Properties
- High Tensile Strength (≥50 MPa): Ideal for rigid applications like pressure pipes and structural panels.
- Chemical Resistance: Withstands exposure to acids, alkalis, oils, and alcohols, suitable for industrial liners and chemical storage tanks.
- Thermal Stability (Decomposition Temp ≥220°C): Reduces degradation risks during high-temperature processing.
Sustainability & Compliance
- REACH & RoHS Compliant: Safe for food-contact packaging, children’s toys, and medical devices.
- Eco-Friendly Formulation: Compatible with bio-based plasticizers and lead-free stabilizers for greener product lines.
- Recyclable: Supports circular economy initiatives in PVC waste management.

Production Process
Yili SG-5 is manufactured using China’s advanced suspension polymerization technology, combining precision engineering with rigorous quality protocols:
- Monomer Purification: Vinyl chloride monomer (VCM) is purified to remove impurities, ensuring high-purity polymerization.
- Reactor Polymerization: Controlled-temperature reactors with high-shear agitators produce uniform PVC grains.
- Stripping & Drying: Residual VCM is reduced to <1 ppm via steam stripping, followed by fluidized-bed drying for optimal moisture control (≤0.3%).
- Screening & Blending: Particles are sieved to 100–150 μm and homogenized for batch consistency.
Packaging & Storage
- Packaging: 25.0 ± 0.2 kg kraft paper and polypropylene woven composite bags with inner polyethylene liners for moisture protection.
- Storage: Store in a dry, ventilated warehouse at temperatures below 30°C, away from direct sunlight and heat sources.
- Shelf Life: 12 months under recommended conditions.
- Transportation: Use covered, clean vehicles to prevent contamination; avoid rough handling to preserve bag integrity.
