Grade A+ is designed to provide the highest gloss and superior mechanical properties while maintaining the lowest specific gravity among the available sheathing grades. This combination ensures both excellent visual appearance and robust performance in cable applications.

The product is rated for a service temperature of 70°C and a working voltage of 0.6/1 kV, making it suitable for standard flexible cable applications. In terms of international standards, Grade A+ is equivalent to PVC/A according to IEC 60502-1, ensuring compliance with established quality and safety requirements.

This grade is ideal for manufacturers seeking a high-performance, visually appealing, and standard-compliant cable sheathing solution that balances mechanical strength with reduced material density.

This grade is engineered with an optimal specific gravity that fully complies with the requirements of PVC/D IEC 60227 standards. In addition to meeting these strict standards, Grade A provides a superior surface gloss, ensuring both technical performance and an enhanced visual finish for the final product.

Its balanced formulation offers excellent processability, mechanical strength, and durability, making it a reliable choice for high-quality flexible cable sheathing. The glossy surface finish not only improves the aesthetic appearance of the cables but also reflects the precision and stability of the compound during production.

**** A comparable grade with the same quality and specific gravity is available under the code 125CCZ 014, offering manufacturers a dependable alternative for consistent production results.

Among the different grades of flexible cable sheathing compounds that comply with IEC 60227 standards, Grade B stands out as the most economical option. This grade is characterized by its highest specific gravity, which is achieved through optimized formulation and careful selection of raw materials.

While it offers a cost-effective solution, it still maintains compliance with the essential mechanical and electrical requirements defined by the standard, making it suitable for applications where affordability is prioritized without compromising on basic performance.

Grade B is therefore widely used in general-purpose flexible cables, providing manufacturers with an option that balances standard compliance, acceptable durability, and reduced production costs, making it an attractive choice for price-sensitive markets.

PVC compound type ST2 is a specially engineered formulation developed for high-temperature cable insulation and sheathing, supporting a continuous working temperature of up to 90 °C. It incorporates advanced heat stabilizers, high-quality PVC resin, and precise lubricant systems to ensure reliable performance under demanding thermal and mechanical conditions.
The compound provides excellent resistance to heat,  moisture while maintaining flexibility and mechanical strength over time. This makes it an ideal material for automotive, industrial, and high-temperature electrical cables.
Its smooth and glossy finish, combined with color stability and ease of processing during extrusion, ensures a consistent, durable, and professional final product.
