Advanced Sheathing PVC Compounds for Durable and Safe Cables

Reliable Protection for Every Electrical and Communication Cable

In the modern electrical and communication industry, cable protection is a decisive factor that defines system performance, longevity and safety. The outer sheath or insulation compound serves as the first line of defence against mechanical stress, temperature variations, moisture and chemical exposure. Selecting the right polymer compound ensures that every cable performs efficiently in diverse industrial and environmental conditions.

At DEV Polymer, we bring over two decades of experience and innovation to develop Sheathing PVC Compounds that deliver exceptional mechanical durability, chemical resistance and electrical insulation. Our ST series compounds—ST1, ST2 and ST3 are precisely engineered to meet international performance standards for wire and cable applications used in residential, industrial and communication networks.

Why Sheathing Compounds are Essential for Reliable Wiring?

Cables encounter extreme stress during manufacturing, installation and daily operation. Exposure to heat, oils, UV rays and environmental contaminants can lead to insulation cracks, surface degradation and reduced electrical reliability. A high-performance sheathing compound ensures:

• Electrical Safety by maintaining consistent insulation resistance.

• Mechanical Protection against abrasion, bending and pulling forces.

• Thermal Stability to sustain operation in varying temperatures.

• Chemical Resistance to guard against oils, acids and industrial vapours.

• Long-Term Durability under outdoor and indoor service conditions.

Each DEV Polymer ST compound is formulated to ensure dependable insulation performance while maintaining the flexibility and strength that modern cable designs demand.
