This resin boasts a high plasticizer absorption rate, making it ideal for the production of flexible PVC compounds, while its high K-value ensures articles with excellent rigidity and strength. The resin’s controlled processing characteristics make it suitable for a wide range of industrial applications, including electrical insulation, wire coatings, and automotive parts, where high thermal stability and mechanical integrity are essential.

IRAN REQUEST provides premium-quality PVC S70 resin, manufactured according to the highest standards, ensuring consistent performance and reliability across various applications.

Technical Specifications of PVC S70 Resin

Key Characteristics and Benefits of PVC S70 Resin

1. Inherent Viscosity (98 – 102 ml/g)
   The inherent viscosity range of 98-102 ml/g ensures that PVC S70 resin has a high molecular weight, which is critical for applications that demand enhanced mechanical strength, tensile properties, and dimensional stability. This viscosity range makes it particularly suitable for processing via extrusion, molding, and other techniques that require durable, high-performance products.

2. High K-Value (69 – 71)
   The K-value of 69-71 indicates that the resin has a high molecular weight, which translates into excellent strength, impact resistance, and stability. This is a key factor in determining the final properties of PVC products, such as rigidity, mechanical strength, and chemical resistance. It is particularly beneficial for producing materials that require good resistance to wear and tear, like pipes, profiles, and automotive components.

3. High Plasticizer Absorption Rate
   One of the standout features of PVC S70 is its high rate of plasticizer absorption. This property enables the resin to absorb more plasticizer during compounding, which enhances the flexibility, softness, and workability of the final product. It is particularly valuable for manufacturing flexible PVC products, such as coatings, wires, and automotive parts, where flexibility is crucial without sacrificing durability.

4. Excellent Dielectric Properties
   PVC S70 resin has excellent dielectric properties, making it ideal for electrical insulation and cable coatings. The resin ensures that the electrical components retain their integrity even under high voltage and temperature conditions. This is an important characteristic for industries such as electronics, power transmission, and automotive, where electrical insulation materials are critical.

5. Outstanding Thermal Stability
   The resin’s thermal stability ensures that it can withstand high processing temperatures without degradation. This makes it suitable for the production of high-performance products that are exposed to harsh environmental conditions, such as automotive components and construction materials, where thermal resistance is critical for long-term durability.

6. Low Volatile Matter (Max 0.5%)
   With a volatile matter content of less than 0.5%, PVC S70 resin ensures minimal outgassing during processing. This leads to a cleaner production environment and better final product quality, particularly important in high-precision applications like electrical insulation and automotive components.

7. Low Porosity (0.28 – 0.32 ml/g)
   The low porosity of PVC S70 resin contributes to a smooth, high-quality finish in the final product. This is especially important in applications where surface quality is crucial, such as films, sheets, and coatings, where air pockets or uneven surfaces can compromise product performance and aesthetics.

8. High Bulk Density (440 – 500 g/l)
   The high bulk density of PVC S70 ensures efficient packing and consistent processing during manufacturing. It also improves the flowability of the resin during extrusion and molding, allowing for more stable and efficient production processes with minimal waste. This characteristic makes PVC S70 highly suitable for high-throughput applications where speed and consistency are essential.

9. Particle Size Distribution (0.50 – 0.85 mm, Retained on 200 mesh)
   The controlled particle size distribution (ranging from 0.50 – 0.85 mm) ensures that PVC S70 resin has optimal flow properties during processing, reducing the risk of blockages or uneven processing. This consistent particle size distribution also helps in maintaining uniformity in the final product.
