PVC E72 - Grade E-7244 is a high-performance emulsion polyvinyl chloride (E-PVC) produced by Arvand Petrochemical Company. This specific grade is designed for applications requiring enhanced durability and thermal stability, making it suitable for specialized industrial uses.
 
Key Characteristics:
High K-Value: With a K-Value range of 71-73, PVC E72 exhibits high molecular weight characteristics, indicating a higher degree of polymerization. This translates to superior mechanical strength and stiffness, making it ideal for applications that require robust and durable materials.
Thermal Stability: PVC E72 offers excellent thermostability, with a capability to withstand over 20 minutes in the Mathiss drying oven according to the Vinnolit THMA 180 and EN 11468 standards. This feature ensures that the material maintains its integrity and performance under high temperatures during processing, making it suitable for complex manufacturing processes.
Low Volatile Matter: Consistent across the series, this grade also maintains a volatile matter content of ≤0.3%, as per ISO 7764/2 and ISO 1269 standards. This low level of volatiles ensures minimal impurities and evaporation at high temperatures, which is crucial for maintaining quality and safety during the manufacturing and application phases.
Sieve Analysis: This grade ensures a very fine particle size with ≥95% of the particles being larger than 63 µm and ≤1.5% larger than 250 µm, facilitating uniform melting and processing while providing a smooth finish in end products.
Methanol Extract: At ≤2.5%, as measured by DIN 53738 and ISO 6427, this parameter indicates the resin's resistance to solvents, making it suitable for applications where chemical resistance is essential.
Residual VCM: Maintaining safety and environmental standards, PVC E72 has a residual vinyl chloride monomer content of ≤1 ppm, ensuring compliance with health regulations and minimizing potential health risks.
 
Applications:
Wall Covering: The robust characteristics of PVC E72 make it highly suitable for producing wall coverings that require durability against physical and environmental stressors.
Leather Foam: Used in the production of synthetic leather, providing a product that is both aesthetically pleasing and durable.
Cushion Floor: Its strength and flexibility make it ideal for cushion flooring applications where comfort, longevity, and resistance to wear and tear are required.
 
Conclusion
PVC E72 - Grade E-7244 stands out for its high K-value, excellent thermal stability, and low volatile content, making it a preferred choice for manufacturers who need a reliable and high-quality material for demanding applications such as wall coverings, leather foam, and cushion floors. Its meticulous formulation and testing ensure that it meets the high standards required for advanced industrial applications.
