Polyvinyl Chloride PVC Resin of China PVC Granules Producer 25kg Virgin Injection Grade SG3 SG5 SG7 SG8 Model
Description
PVC SG5 is medium-molecular-weight general suspension PVC resin with moderate polymerization degree, the most widely used universal PVC raw material in the market. It acts as a key intermediate connecting upstream chemical raw materials and downstream plastic finished products.
1. Balanced mechanical performance and processing fluidity, fit for extrusion, injection molding, calendering and thermoforming.
2. High cost performance with stable raw material cost.
3. Good compatibility with various additives, capable of producing rigid and flexible PVC products.
4. All production and testing comply with national standard GB/T 5761-2018.
· Appearance: Loose white amorphous powder, excellent fluidity and plasticizing property
· Standard Package: 25kg moisture-proof woven bag printed with “PVC Resin SG-5”
K-value represents molecular weight and determines processing performance.
· Superior Grade: K66~68, average polymerization degree 980-1135, ideal for pipes, profiles and sheets
· First Grade: K63~65, suitable for ordinary general products
1. Apparent Density: ≥0.48g/mL (Superior Grade); ≥0.45g/mL (First Grade) High apparent density avoids powder bridging and ensures stable feeding during production.
2. True Density: About 1.40g/cm³, used for cost calculation and structural design of plastic products.
