SG-5 Suspension PVC Resin with Ultra-low 1ppm VCM, High 0.54g/ml Density, and 22g/100g Plasticizer Absorption

1. Product Introduction
SG-5 is universal medium molecular weight suspension polyvinyl chloride resin. Its K value ranges from 66 to 68 with viscosity number 113ml/g, balancing mechanical strength and melt fluidity. It features low fish eyes, high apparent density, excellent thermal stability and moderate plasticizer absorption. Widely used for rigid PVC products such as water supply & drainage pipes, plastic profiles, rigid sheets and injection fittings. All test indicators of this batch reach the superior class standard of GB/T 5761-2006.

3. Core Product Advantages

1. Moderate molecular weight, balanced rigidity and processing fluidity, suitable for twin-screw extrusion and calendering production.
2. High apparent density of 0.54g/ml, improving single extrusion output and reducing dust generation during mixing.
3. Only 19 impurity particles and low fish eye content, effectively eliminate surface speckles and pinholes of finished rigid products.
4. Ultra-low residual VCM of 1ppm, complying with environmental and export product requirements.
5. Excellent thermal stability under 160℃ high temperature, less yellowing during long-time processing.
6. Plasticizer absorption up to 22g/100g, good compatibility with calcium-zinc and lead salt stabilizer systems.

4. Recommended Application Fields

• Rigid PVC water supply & drainage pipes and pipe fittings
• Plastic door & window profiles, wall panels and decorative extruded strips
• Calendered rigid sheets, foamed boards, corrugated plastic panels
• PVC cable ducts, electrical plastic injection parts

5. Packaging Specification
Standard package: 25kg moisture-proof composite paper bag
Bulk option: 500kg / 1000kg ton jumbo bag

6. Storage & Operation Safety Guidance

Storage Requirements
Store in dry, cool and ventilated warehouse, avoid moisture, high temperature and direct sunlight. Seal bags tightly after opening to prevent moisture absorption and agglomeration. Adopt first-in first-out inventory management.

Operation Safety
Wear dust mask, protective gloves and safety goggles during feeding and mixing to reduce dust inhalation. Clean skin thoroughly with soap after contact with resin powder.

7. Quality Statement
All inspection items fully meet the superior class requirements of GB/T 5761-2006, all test judgements are PASS. All data are authentic factory lab test results for reference only. Actual processing performance is affected by stabilizer, filler formula and extrusion parameters. Small batch trial mixing before mass production is recommended to verify adaptability.
